VFR owners' thread, for VFRPS members and prospective members

[gatch]

last 18" l bought for my nc24 was $250 12 years ago

I can either use the 18" rear, or get hold of some vfr750 wheels, which will be much cheaper and plentiful then rvf items. There's one on trademe at the mo for $500 !

Only trick is the vfr750 wheels are 4 bolt, so I'll have turn up a new hub to mount it, but that's no trouble. Also it's a 5" wide, so the tires would be 160section, but that just means I'll have to ride it harder :D

Yeah man. I'll be out for a hoon tomorrow. A mate has just bought an ER650 protwin thing and another mate is bringing his rs125s for both days. My bucket will be there too, hopefully I can take it out in the slow group and give it a tune.

[koba]

18's aren't much of a problem at all. Its the 16inch front on mine that is a shit to get flash rubber for!

[gatch]

I got one good dry warm session in today. Did 1.27.

I feel there is more time to gain, particularly through t1 and higgins. I Can't wait to get some forks sorted, then get my shiny new shock in. Then see how it goes. I'll be stoked when I get under 1.20.

Thought I'd give all you Honda Homos (note to Hitcher - no apostrophe) a bit of a heads-up. Bayride in Towel-Wronger have a rather tidy RC30 on display in their showroom, came in today apparently. Feel free to go & jizz all over it.

is it for sale?

is it for sale?

Nope - That was the first thing that came to my mind. The tosser salesman I spoke to gave the impression that he'd rather not have it in the shop, seeing as it's a Honda. Fuckwit.

I think there is a track day at manfield, the last weekend of this month. I'll be at that one too.

It's gold, ride to the track with tools and spares in pannier bags. Cane it for a bit, then ride past all the dudes with their bikes on trailers on the way home.

I know there is a MotoTT day coming up on a friday, I was going to flag but time off work is a no-go right now.

My VFR is quietly rotting while I wait for the rear shock to fix itself.

whats going on in here green rules

[actungbaby]

That particular wrecker I feel is a bit of a retard...asked for a cbr600 1991-1998 left handlebar switch and he sent me one from an 04-08, when I contacted him he was like "oh I've got the other one here, honda often switches plugs and wiring between years". Retard. Honda tries to use as many parts again as possible! (as do most manufacturers...gpx250 anyone?)

they do actually well know for changing parts between the years but yes am been less than impressed with bike wreakers here

so go to england insteed spent 600 nz so far i cant be bothered with people here seems like your doing them fav to buy of them

I wanted to buy vtr 250 engine of one all got was oh thats wrong engine and u have to swap the motor which i think is

A w%$k anyway casue why do need hassle sending a engine thats junk anyway and pay 1,200 for privllege no thanks dude

And others i asked for vt 260 engine oh yeah either dont have one say that no we try gte you one some time its like

It's irrelevant anyhow. I can get a set of slicks at my house for around $550 (17" front, 18" rear), which is pretty much the going rate for slicks anyway.

I'm pretty carefully considering buying that rim for the VFR rolling chassis I have. (with rego on hold). Then all I need is a RD500 motor, and a whole buncha money. A whoooooole bunch.

[actungbaby]

I wonder if that's the one that was for sale at Casbolts when I lived in Chch (1994-1996)? I had a VF500 at the time, and dearly wanted to buy it. Ended up keeping the VF for a few more years, before buying a VFR like Warr's one.
me too i was so close to buying that bike as well just was moving to plamerston north after working last 8 years in chch
my true home town .. only reason was declined on the finance because if just left my job and was inbetween jobs aghhhh

20 Plus years latter well fast froward to 2012 and i finally managed to get one

was it the amiercian vfr 700 model i think i did like white one too i remmber drooling of both models in there

has anyone ever seen proper flat slide racing carbs for a nc30 fcr 33MM ? can you still get them

Keihin FCR33's are still available - but you'd have to buy a bank of four and cut them up then make linkages....not hard for a man like you.

The Roberts bikes in the early couple of seasons of F3 here had what were rumoured to be HRC kit carbs......

http://www.jb-power.co.jp/new/info.php?seq=8

[Grumph]

The FCR's in all those have unmodified bodies as far as i can see. Linkages are a pain. The RC30's have more room obviously. From the sound of things there may be a few sets for the NC30's floating round but if you can't find one then I'm sure it's possible to cut an inline set to suit.

The biggest thing with the NC's is to finish the crank properly - Honda don't ! Properly radiused oil holes on the crank will keep the bottom end together as will going to the thinnest shells - yellow if I remember right. They're way too tight as standard.

The first two NC30's to be raced in ChCh both did big ends, luckily with no crank damage. I sorted both well before Casbolts even had a parts fische.

[lukemillar]

Mine are 32mm. The bodies are unmodified but the linkages are pretty complex! I have a lot of detail pics if your are interested because as your probably have found out, these things are like rocking horse shit - even finding any pics on the net are near impossible:

Nah, I didn't but I really wish I had! I have some better needles now for the FCR's and have fixed up the accelerator pump, so I should be able to get a better dyno readout. Can't find the exact needles I need and if I want to order them from Japan, I have to order minimum of 20, which works out about $800 :shit: so I'm just gonna stick with what I have.

I just want my POWER!!! back. The fxr just don't have the same feeling (tho I have been enjoying the fuel savings)

are all four plugs and both coils not functional?

Pretty uncommon, although there are a few spares floating around from people swapping out their CDIs for programmable ones.

I'd say check the connectors for corrosion and test the harness for continuity. Broken wires and corroded connections are pretty common, especially if the bike hasn't always been garaged.

na none of the plugs or any of the 4 coils spark for me, yet I'm getting the voltages & resistances I should expect along the lines. So the next suggestion was the CDI

Yea that was one of my beginning thoughts but I have tested resistance across them & it's within spec, so unless they're known to go while still giving spec resistance I'd assume it's still good?

considering the age of the bike you really should try physically unplugging, inspecting and replugging all the plugs if you havn't already done so. A can of CO contact cleaner may help. What your multimeter says and what the bike sees under electrical load may not be the same.

otherwise, yes, swapping with a good one would be a good test - if you can find one!

Have 86 VFR700F sitting in shed in process of fixing up and putting back on road, Started and ran last time I tested. can hook up CDI unit and test, just need to get unit to Levin
Offers there..

might have to take you up on that, PM me your address I'll see if I can get it couriered up before the weekend along with a return ticket if thats alright?

[nzvlogger]

Any of you boys got a pair of forks, triple clamps, and front discs laying around? lol I want to get rid of the TZR forks (one is leaking anyway)

[jono035]

I'd use it as an excuse to move to a programmable CDI :D

I've got a spare CDI floating around. Could send that down for you to test with if need be.

[actungbaby]

you taking the piss? its hard to tell.

Luke is putting Keihin FCR carburettors on his NC30. I adore the FCR's though they are notoriously expensive and difficult to set up. Plus he has to make mounts and linkages etc.


http://www.sudco.com/keihin.html

Nope i never even seen my carbs let alone no what numbers there called hehe

remember not all us here are experts like you fellows so i know the nc30 is a 400cc vfour honda the one with out single sided swing arm ?

[jono035]

Just finally got around to installing the Ignitech programmable CDI that I bought ages ago.

Took the bike for a blast, no more noticeable flat spot then surge at 7k, instead it's smooth through the range. I can't tell whether the bike would be noticeably faster or not, but it's way nicer to ride around town.

Also, apparently my tacho was reading 10% high, too...

Edit: Just having a bit more of a play with it, it seems to ignore the side-stand cut off switch. There was a box in the software that said 'inputs for neutral side and stand' but checking it just made the bike never start, no matter what clutch/shifter/side stand position it was in... Anyone else using one of these and trying to keep the cut-out?

Grab a can of that, pull all the connectors and give the contacts a liberal dosing. You can use a cotton bud and some isopropyl alcohol, but that stuff is easier and better on the female faston type connectors.

Look for any corrosion or other white/blue powdery stuff both on the contacts and in the backshells that they're clipped into. Give each wire a firm tug to try pull it out of the backshell, sometimes they'll be broken or the crimps will have failed.

Go along the loom section by section looking for any spots where it might have rubbed against the frame or something and worn through. Check that you've got good continuity between the battery -ve terminal and ground, both on the engine and on the frame.

Beyond that, I have no ideas other than find someone with an oscilloscope and start checking sensor outputs.

[crazy man]

Haven't put it in yet. I have a hunch that it would push the front end about something fierce.

Will get some forks first, then put the shock in.hows the racing gone this weekend on the classic's

[gatch]

hows the racing gone this weekend on the classic's

Not bad aye. Snagged a couple of thirds, not bad considering Nick Cole and another very fast bloke named Chris Swallow were at the front of the pack..

Had some good battles with a dude that used to w00p my ass. Managed to get off the track and onto the grass at 100mph on the top of the hill, stayed on the bike though. Primo weekend man.

Only problem now is waiting for the next round of racing eh..

Yeah man they are very very quick dudes on very well sorted bikes..

I haven't had my bucket out for about 8 months. I'm making a new fuel tank for it at the moment, as I lost the key to the stock one.. Once the tank is in and a cover made for it, I'll get out when I can..

I see you made a frame for a dudes bucket. Looks pretty mint.

Isn't that the truth! With such a good weekend as we just had, I can't wait to get out on the track next weekend at Hampton Downs too!

Two weekends of racing, then followed immediately by spectating at Paeroa. This is shaping up to be a fine February!

I am gathering bits for my VFR rolling chassis. It will need a new engine. I had a brilliant idea of using a new Bonneville motor in it for shits and giggles. Except the new Bonnies have the output sprocket on the right, eht VFR motor has it on the left. Short of turning the swingarm upside down (MAJOR hassle $$$ and time and engineering) I am thinking of other motor options.

My favourite one was an RD500 motor but the exhaust plumbing in particular is daunting, and again BIG $$. I could always pick up another motor for not much money, but the idea of MOAR power is intriguing. I have searched but I wonder if anyone has shoehorned a VFR750 motor into one of these frames?

ideas/suggestions anyone?

Theres an RC-51 SP2 motor on tardme for $3600 which has potential. issues would likely be front wheel clearance and snapping the frame in half like a twiglet the first time it was opened up. That 89 hp NC30 sounds like fun though, right? (with the 750 motor).

Its all bullshit at present really but I do have to do something with this roller (plus it has rego on hold......)

Any new motor in one of those frames is going to take fairly serious coin. Fabrication, machining and welding etc. Unless you want to be real rude and make steel adapter plates to hold up the motor.

My idea for the motor.. 750 or 900ss vtwin duc. Aircooled 2 valve with big fuck off THUNDEROUS megaphones. It would sound bad as fuck and would certainly turn some heads.

So far still no spark, but I've depleted my batt so thats now on charge for the night. I'm gonna check the kill switch again thoroughly make sure thats not the prob, but other than that It'll have to wait till Fri before I can continue further (got paintball tomorrow).

Norton Commando engine maybe? :)

Dunno, just thinking aloud really. Going to reassemble the rolling chassis soon.

[Icemaestro]

Sure I remembered an article in an old bike mag about someone putting a 750 engine in the nc30...and it being pretty straightforward...they put the 900 engine in the cbr600 all the time...just often have to put some mounting plates off the original front mounts

to be honest that would be my first preference assuming I go that route. The link above (VFR750 into NC30) was excellent.

what about a VTR750 firestorm motor, wouldn't have the problem of the RC-51 as I don't think they make that much power, plus there are a few wrecks on trademe?

I doubt you would fit the finning in between the frame spars. A 920 NRE motor would be sick as fuck though. Would probably melt the frame from it's sheer awesomeness though. And melt your face.

should also be cheap-ish: Ideally an EFI one. the only real drama I think would be the rear headers: they're a PITA on an NC30, but with LESS clearance? urk.

but yeah, an easy, reliable 80+ hp NC30? WOO!

Plus the only new money in it is the motor etc: The rolling chassis is free (actually anything but free, but since I already own it, it is essentially free, even though I dare not count the amount of money sunk into NC30 bits over the years...

Hey guys n gals, i just bought my first VFR 400R....so no mechanical issues yet. Seems pretty straight and handles well (from the test ride anyway) Im suspended at the 'mo, lost my demerits through speeding on my GSXR...shame. So i decided a down size might be a good idea for a while at least. the only weird thing is the 'SPEED' warning light on the instrument panel. What's that all about? Never encounted that before, so excuse my ignorance ha ha. Also, some tips on service or maintainence intervals or just general comments on this model bike would be greatly appriciated. 1991 VFR 400R. cheers aye:)

1991 = NC30, so gear driven cams, infrequent (but expensive valve adjustments) maintenance. The motors in stock form are renowned for reliability: key is oil and filter changes. They can be a bit hard on spark plugs I find and spark plugs are VERY expensive. Check the air filter too, just the normal maintenance stuff you'd do on any bike. The known issues with them revolve around the regulator/rectifier (check its charging properly), and the restricted top speed at 180kph: easy to fix.

If it has stock suspension it will need a rebuild at least probably, or cartidge emulators in the forks and maybe a respring, and a shock rebuild or replacement. the rear tyre size is 18 inch which might cause some issues getting sticky rubber for but it is available. The hot ticket is an RVF400 17 inch rear wheel, but if you do that you will need the new shock to get back the rear ride height you've lost.

Great bikes, truly. Enjoy.

[motordrummer]

Hey thanks for that...and that 'Speed' warning light on the instrument panel? it flashed on and off at relatively low revs at a 100kph...anything to worry 'bout?

wouldnt thinks o: they were all Jap imports and I think it is or was a mandatory requirement in Nippon that a light came on if you exceeded the speed limit. Take the bulb out?

[sil3nt]

I also have a 91 NC30. Doesn't have a speed light though. My 250 GPX has one that comes on at 80kph because that is what the speed limit was for learners in japan.

With the gearing on the NC30 its hard not to be speeding really.

Hey scuba_steve that couldbe a bit frustrating. Run through the below procedure and let meknow. You may have done some or all of it already, but just in case..
We know CDI unit works..Well it did on my machine.
Disconnect plugs at CDI unit. Locate the 3 pair wires for the three pulse generators-perform resistance test across each of the pairs. This will test all wiring and connections in the lines to pulse generators.
Reconnect plugs and turn on ignition. Locate power feed Black/White wire check for 12 volts (approx). Locate 4 wires for the 4 ignition coils and test for 12volts (approx) at the plug
This will test all power feeds including kill switch and power to the coils.
Turn off ignition and locate earth wire and resistance test to frame or Battery negative approx 0 ohm resistance
If these tests check OK then you have something strange, If you want a hand I'm bout due for aspin around the "block" . I can pack up the oscilloscope drop in for coffee and a bit of a look see.
Just been through this saga myself, my issue turned out to be an open circuit pulse generator, to prove it was the real source of the problem and that the CDI unit worked I broke open and performed a crude rebuild of the pulse generator. I now need to locate a replacement unit (pulsegenerator). Hint hint to anybody reading this and may know where I can pick one up aye. :msn-wink:

If you can find an RVF400 rim then it is a straight swap. I have been running a 160 rear with no hassles of clearance. Only thing I did was increase my ride height for the decrease in wheel diameter, but that can also be done with the RVF linkage as well. Only problem I get is slight exhaust/swingaram interference.

My main motivation for doing it was range of tyres available rather than handling.

Yeah well sorted, took the block down to Motomart and they popped it off for me. although I got Rick Oliver to chuck one in the last order I got from him. Nope wasn't me riding the RVF as mines in bits in my garage. Worlds longest rebuild.

I'm up in Upper Hutt btw.

[Scuba_Steve]

Cheers Gingin I went through all the tests, everything seemed to be reporting ok.
So stuck I went back to investigate a noise I thought I was hearing upfront (which I was putting off as people were writing it off as "lack of compression", "normal" for these bikes, or "nothing to worry about" etc, etc & being upfront behind the radiator I was hoping to avoid pulling everything off just to get to it. So I guess I was "hearing what I wanted" rather than going with gut)
So after pulling off all the fairings emptying the radiator & pulling that off, taking off the front cover. Sitting at the bottom in some oil I think I might have found my problem? (photo'd)
4 small blue springs & 2 chew'd pieces of metal.
So hopefully someone might be able to tell me where these came from & what I'm going to need to replace and also confirm my problem is found (I'd hate to find I have multiple issues).

[DrunkenMistake]

They look like Rocker springs... haha
Or clutch springs but I would put money on Rocker Springs

[HenryDorsetCase]

what is the "Front cover" you pulled off? which side of the engine? or are you talking about the top rockerbox cover for the front pair of cylinders.

Pretty sure though that having those bits floating around might be slightly out of the HRC guidelines for these motors.......

yea the top cover over the 2 front cylinders (sorry I'm learning this as I go & useless with names)
Haynes manual appears to call it the valve cover I think?

[jono035]

Man, I sure as hell hope you're trolling us.

Just checked the photos from when I had the heads off mine, it doesn't look like the valve springs that I have. They are all noticeably taller and have more coils on them.

Either way, I'd take a shitload more photos of the cams/rockers from a bunch of angles and post them.

Edit: Well, if they are valve springs, then with 8 valves per head, technically you can have 4 broken valves and still have the engine... cough... operational? :mellow:

[jono035]

I'm still wondering if I'm getting trolled, but do you have a photo showing the size of those springs?

Those are the rocker springs there... There is a smaller spring inside the larger ones shown there, but they are still full height.

Also, I've never done anything to the clutch, but it doesn't appear they use coil springs...

It is an NC30 that you've got, right?

the 4 springs are 15mm & look complete, I don't think it's an NC30? but I don't know it's the 1986 VFR700FG so whatever that ran?

They look to big too be clutch springs, my money would be valve springs, they seem to have the same amount of loops in the two photos not to say they are different sizes still though I guess

[HenryDorsetCase]

no way are they clutch springs. If we've taken off the front valve cover and thats where they are, then they're from round that area logically. Plus mr clutch is on the side of the engine a LONG way away from where these bits are. If they were clutch parts they'd have grenaded teh motor by now, surely.

Its a VFR700 so it appears to have screw and locknut valve lash adjustment? but it has a gear train to drive the cams it seems. Just throwing ideas out (I have not seen inside one of these motors so this is just guesswork, OK). maybe a backlash adjuster in the gear train? inner valve spring? (though I agree they look to small) is there an obvious place where the bits have metal have come from?

http://www.vfrdiscussion.com/forum/uploads/1263379567/gallery_3647_3505_153085.jpg is a random internet shot for VFR700 valve train. Does it look like yours? any bits there that arent on yours?

[tigertim20]

They look to big too be clutch springs, my money would be valve springs, they seem to have the same amount of loops in the two photos not to say they are different sizes still though I guess

if you think thats too big to be a clutch spring, you need to refresh your clutch knowledge my young friend. at a total height of 20mm Id say theyd be more like too small to be clutch springs!

My favourite one was an RD500 motor but the exhaust plumbing in particular is daunting, and again BIG $$. I could always pick up another motor for not much money, but the idea of MOAR power is intriguing. I have searched but I wonder if anyone has shoehorned a VFR750 motor into one of these frames?

ideas/suggestions anyone?
There one on trademe at the moment only problem i got when see engines for sale is
You got to wonder why anyone take a working motor out in the first place if was going perfectly well.
As i brought 2 dudes of trademe and was told they both ran yeah right , with rust inside the motor
And con rod bearings so think like paper , and to be honest most whould no better if we got given any said motor
it might turn over fine does not mean much though
from know on, I will only buy motor, i see running because even the carbs are blocked up through years no use
Been qouted big bucks just have them cleaned up big bucks damm.

I might get tips from each other i got vt 250 rolling chassis with no motor
I rekon big single whould be cool also , and in your good handling frame.

if its a twin spar one . rd 500 engine you have real handfull of motorbike
The best part these bikes is there easy to ride why make them worse

A pararell Twin be nice i agree you have to get the balance right weight wise
A not sure in bike you want weight on the front wheel 60/40 split ?hmm on car in middle best
Dont think this is good idea on a bike though

I think if you weighed the front wheel and then the back on set of bathroom scales
With motor in the frame then move it to adjust balance , ride it and see how it feels then move the brackets
that bolt the engine to the frame , you still want rear to have grip too mind you

You have to get the engine to the rear sproket front sprocket inline .
and then you whould have the suspension spring rates front & back
If motor is alot diffrent weight esp heavy Vfr 750 the pro link linkage ratio rates might need to be changed also
You whould need wider rims also, that mean changes also alot to think about

oh ps am getting my vt 500 motorbike soon i wonder if these motors whould be a good fit oh its got shaft drive
Maybe bros engine whould be nice there good motor too relaible sound nice.

[DrunkenMistake]

if you think thats too big to be a clutch spring, you need to refresh your clutch knowledge my young friend. at a total height of 20mm Id say theyd be more like too small to be clutch springs!

Look at the post time, we both posted at the same time, so I have only just noticed pictures were posted. <_<

how would clutch springs get in teh front cam cover though? and presumably without lunching the rest of the motor on the way thru?

[jono035]

Didn't realise it was a VFR700, for some reason I thought you had an NC30... In that case, ignore my valve springs.

I dunno, the idea of the engine keeping running with some valve springs loose in it seems pretty mind-boggling as well, although a shitload more likely. Perhaps the previous owner used the head as storage for spares? <_<

[Scuba_Steve]

Well just got home from paintball, went and had another proper look (with more light this time). found where they came from
On the other side (right-hand when facing the bike) of the 2 big middle cogs are something? the top cogs one is broken this is where the 2 chewed pieces of metal & the 4 small springs have come from.
So pictured is the whole front showing the 2 cogs, the complete bottom cog, & the broken top cog

[jono035]

Oh, OF COURSE! The cam gears are 2 gears on the same shaft countersprung together, I assume for backlash/chatter prevention. Knew they didn't look like valve springs :D

So the keeper for the springs has failed, and the springs and bits have ended up sitting in the head. I would probably assume that there are bits and pieces that have made their way into the sump, too. At least the pieces will be steel, so at a bare minimum, do an oil/filter change and get one of those magnetic sump plugs.

Take a careful look around the entire head and see if you can see anything else broken or with any major dings out of it (specifically the cam gears and cam lobe surfaces). Take the timing cover off and turn the engine over (making sure to turn it forwards, should be marked) and inspect all the moving bits in there to see if anything is marked up or chipped.

As for fixing the problem itself, if you can get a replacement intake cam with its matching holder and journals from a wrecker then that should just drop straight in. If you can only get the cam then I don't know what the deal is. Check all the bits for service tolerances and then just give it a shot?

Pretty easy procedure, but you will definitely need a torque wrench and probably some molybdenum grease if you want to do it by the book.

That's my thoroughly unprofessional opinion on what I'd do just as a rough starting point.

Edit: That's probably the best possible outcome for finding random springs loose around your rockers.

[more_fasterer]

^^^ Agreed. Just make sure you rotate the engine to TDC, and ensure the new cam is installed in exactly the same position as the old one.



Just finally got around to installing the Ignitech programmable CDI that I bought ages ago.

Took the bike for a blast, no more noticeable flat spot then surge at 7k, instead it's smooth through the range. I can't tell whether the bike would be noticeably faster or not, but it's way nicer to ride around town.

Also, apparently my tacho was reading 10% high, too...

Edit: Just having a bit more of a play with it, it seems to ignore the side-stand cut off switch. There was a box in the software that said 'inputs for neutral side and stand' but checking it just made the bike never start, no matter what clutch/shifter/side stand position it was in... Anyone else using one of these and trying to keep the cut-out?



I've just brought one for my RVF, once it's back together I'll let you know about the side stand cut out.

Where did you get the programmable CDI from? Direct from Ignitech?

[motorbyclist]

WOW - at first I thought clutch springs, but too small and WAY too far north...... then sure enough there's where any tappety noises would be coming from!

See something new every day I guess! Jono's advice seems pretty solid


Hey guys n gals, i just bought my first VFR 400R....so no mechanical issues yet. Seems pretty straight and handles well (from the test ride anyway) Im suspended at the 'mo, lost my demerits through speeding on my GSXR...shame. So i decided a down size might be a good idea for a while at least. the only weird thing is the 'SPEED' warning light on the instrument panel. What's that all about? Never encounted that before, so excuse my ignorance ha ha. Also, some tips on service or maintainence intervals or just general comments on this model bike would be greatly appriciated. 1991 VFR 400R. cheers aye:)

Speed light? Photo of said light and whole bike? I'm pretty sure the japanese market NC30 bikes don't have speed lights... you might have an NC21..... NC30 is awesome and has muffler on left hand side, NC21 is far less awesome (but still mechanically solid) and has muffler on right hand side


The motors in stock form are renowned for reliability: key is oil and filter changes. They can be a bit hard on spark plugs I find and spark plugs are VERY expensive.

I find oil every 5,000km and filter every second oil change to be a good recipe for any high-revving and/or sport bike if you want them to last. Oil filter for me every second oil change, air filter and plugs as needed around 20-25K and I usually get the carbs balanced by someone who knows what they're doing around then too.

For road use you don't need to change to a 17" rim unless race slicks become WOF standard. Fitting a wider rear tyre does not enhance handling on the road, either.

Dont be ripped off by NZ bike dealers who want $45 a plug and don't have a clue - $120 for oil filter, air filter and 4 plugs : http://www.davidsilverspares.co.uk/VFR400RK-NC30-1989-JAPANESE/part_22860/

Easiest way to tell the VFR400s apart:

If you have dual swingarms and the exhaust on the RHS, you have a NC21.
If you have a single swingarm with the exhaust on the RHS, you have a NC24.
If you have a single swingarm and the exhaust on the LHS, you have a NC30.

If you have a VFR of any sort, you have chosen wisely.

Be worth strapping some neodymium magnets to the oil filter then???

I doubt you would fit the finning in between the frame spars. A 920 NRE motor would be sick as fuck though. Would probably melt the frame from it's sheer awesomeness though. And melt your face.how meany times did the old guy lap you?

Was trying to simplify Motorbyclist's picture-spam rather than help him out in particular.

[gatch]

1991 = NC30, so gear driven cams, infrequent (but expensive valve adjustments) maintenance. The motors in stock form are renowned for reliability: key is oil and filter changes. They can be a bit hard on spark plugs I find and spark plugs are VERY expensive. Check the air filter too, just the normal maintenance stuff you'd do on any bike. The known issues with them revolve around the regulator/rectifier (check its charging properly), and the restricted top speed at 180kph: easy to fix.

If it has stock suspension it will need a rebuild at least probably, or cartidge emulators in the forks and maybe a respring, and a shock rebuild or replacement. the rear tyre size is 18 inch which might cause some issues getting sticky rubber for but it is available. The hot ticket is an RVF400 17 inch rear wheel, but if you do that you will need the new shock to get back the rear ride height you've lost.

Great bikes, truly. Enjoy.

17" wheel is sort of moot now. You can get some good tires for the road, also can purchase bridgestone slicks (dry and wet for the 18" rear. No need for stupidly expensive wheels :D


If you can find an RVF400 rim then it is a straight swap. I have been running a 160 rear with no hassles of clearance. Only thing I did was increase my ride height for the decrease in wheel diameter, but that can also be done with the RVF linkage as well. Only problem I get is slight exhaust/swingaram interference.

My main motivation for doing it was range of tyres available rather than handling.

Did the rvf linkage make any noticeable to the suspension action ?

Maybe, but it depends on how long the 18's will stick around for! I bought 2 sets of RVF rims from the UK for only slightly more money than people were asking for a second set of NC30 rims (I think I paid about $500 landed per set). Prices seem to have gone up big time here (and there) now though as though people have realized that they are in demand.

I'm still on the 30 linkage. I adjusted my ride height with shock length. I have though modified the NC30 rear linkage though to remove the solid bushing for the lower shock mount - The 35 has a needle bearing here, and you can order/ fit the parts easily/cheaply enough. How much of a difference it makes, I couldn't say, but anything that reduces friction on moving parts can only be a good thing!

You will have to measure the shaft and hole where the bearings are situated. Then take your measurements to skf or saeco and see if they can help.

so I just ordered a (genuine honda) rear disc and rear bearings from the UK, along with air filter, oil filter, plugs, handgrips and bar-ends.

$600 worth with shipping!


So seeing as I'll be playing mechanic for a weekend coming soon (60,000km!), does anyone have a dead motor around? If I'm super-duper keen I might drop the motor out and have a look at the state of 1st and 2nd gear, but if I don't like what I see I'm not sure where I might find parts..... rvf has a different ratio to vfr for first gear, but it might be the selector drum or one of the forks giving me grief (1st-2nd shifts are getting crunchier, pops out of 2nd into first in 1% of shifts, neutral light crapping out - something is giving a metal sliding/scraping feel through the stick and I think it's the selector drum)

tbh I don't see myself dropping the motor unless I have bits on hand - that said I just spent $600 for brake disc (needed, but it was passing wofs regardless) and bearings (not needed, doing "seeing as I'm down there") and peace of mind would be nice - can do valve shims and re-seat valves while I'm at it.... just if bits need replacing I don't want to wait weeks for them to arrive - and not that many bits are available! http://www.cmsnl.com/honda-rvf400rr-nc35-japanese-domestic_model17197/partslist/E14.html

NC30 ratios would be different to the 21 no doubt ? Maybe I'll look for a wrecked motor..



Very, this box is a 30 tho.

Shot. If you find them and they are in good nick, give me a shout. I'd like to have a go at replicating some, the only thing we aren't set up for is cutting the splines. So aside from that, it may work out to be a fairly cheap exercise.

EDIT - Actually if I could put a dividing head on our shaping machine.. The plot thickens.

Does the NC30 not have a cassette type gearbox?

BHAHAHAHA:killingme

negative. if you wanna get at it and get the shafts out, you have to strip the entire motor.

actually I lie, you can leave the front head on if you want.

[ecko_nzed]

Come on my GPX 250 has a cassette gearbox!

These bikes really do sound like absolute cunts to work on. Mechanics must try and hide when someone brings one in.

Once you get the motor out of the frame they're not too bad. some tricky bits if you don't have the right tools, but they come apart pretty easy. I'll give you my opinion on the going back together soon.....

If I ever get my crank and heads back :wait:

I am really good at taking things apart. Not so good at putting things back together.

[motorbyclist]

One in every ten shifts from first to second results in hitting neutral. Every other gear is smooth but first to second can feel rough. Does the NC30 not have a cassette type gearbox?

mine (nc35) isn't one in ten... maybe one in one hundred.... that said it might be higher... happens a few times a week (100-200km/week commute)

the feel through the foot shift suggests some metal on metal sliding contact, ie selector drum or forks... anything really which could in turn lead to improper loading (& subsequent unloading) of gears


If you are going to go split it you may as well get the parts in there machined and undercut. It's not all that expensive and should give a better result, sure I't means the bike might be off the road for a bit longer but it's gotta be worth it.

but i just want to fix it!

I don't need to split it to take a look.... just take the lid off, that's all! (crying on the inside)

30, 35, not fussed!

[motorbyclist]

Haha deleted my post :

they are designed for little japanese hands.

They're also designed for racing - ie it's actually a pretty good setup if you drop the motor and plan on doing everything


Mechanics by and large don't even seem to know what they are..... I recommend taking NC30s to mechanics with specific NC30 experience - it's the difference between 20 minutes skilled labour or 3 hours exploratory surgery. AJ at motohaus can have them stripped down and balancing carbs in 20minutes flat!

See quite a few NC30s in at Honda Hamilton so I would imagine the know what they are up to. I also know one of the boyds motorcycles mechanics has owned one and I was talking to a parts dude there today who currently has one. So I would like to think Hamilton mechanics are familiar with the bikes. Although I would like to check out AJ at some point thanks to the good word put out in the thread.

Yo. You should have a look for that gear box bro. I have a draft plan of how to go about this. I think I could do a pretty good job of it all. Even if the gears are helical cut. Which I think they would, as they are not as noisy as straight cuts.

The only thing I would need to pay for is material cost (I'd use EN39b) and case hardening.

Pretty sure they are straight cut. Except maybe the primary drive.

Blast.

Saw a NC30 steering dampener on TM for $60 this morning, so watchlisted it and hoped for some luck in a couple of days when it closed.

Then the blasted seller added a buy-now for $60 when I was out driving trucks, and some lucky blighter snapped it up.

No bling for the NC30 any time soon then. :(

I saw the damper and thought about it, but I really don't think you need one on the NC30! I have ridden my bike fairly hard and the only time I have ever got the bars to slap was running off the track and going dirt tracking over the bumps!

Nice! looking pretty tidy.

[actungbaby]

Cheers for the offer but Yeah they are different, different to even the Vfr400 which i was hoping would be the same. If i get desperate i could always get the two cracks welded and hope?

well if you take to engineering oufit with good quailty gear the welding make it as good as new unless the casting is cracked all over

well what mean by that the casting just showing signs of just pain old age not just stress fracture

But considering castings much better material these days not old shit metal as my old boss vic whould say die cast 60s crap

Also i forget what you model is i got nc 21 also on the way if you want swap parts that be fine also as long got something to use myself

or do serach on ebay i got replacment for my vfr 750 just have to pay for it that and footpeg and mudguard all brought.

[ecko_nzed]

decided to tidy up my motor before I put it back together. Went with gloss black (that's the only black VHT they had)

Need to take some pics. Well, I need to wait 7 days before I can patch up the bits I missed- Had to do it in the garage with the door shut because of the frickin wind and couldn't see that well :(

Yep, that's the motor. So far I have:

balanced crank
new matched NC35 pistons + rings ( + matched rods)
checked tolerances of pretty much everything internal + cleaned up everything
skimmed heads
some basic porting (seat -> bowl blending, inlets matched to rubbers and casting snot removal)
slotted RVF camshafts
HRC style oil cooler

I just need to finish off the porting and then just start rebuilding the thing.

Still stock - Don't want to kick myself out of the new posties F3 class! I did get NC35 pistons though which are a different design and slightly lighter than the NC30 ones. Some people say they are slightly higher comp the the 30's as well, but I don't think there is much in it

yeah - forks have to remain period which means you must have K model damping rod forks, not the cartridge one from 90+. Shock is open, so that is no issue

It sure as hell doesn't get better on the track. Anything short of progressively winding on the gas through a turn will have you doing all kinds of odd things, bottoming out mid turn and under brakes, massive understeer rear wheel spinning if you hit a bump etc.

the worst thing abuot mine with the stock shock was it dragged its arse on the ground really badly. I thought it was OK, till I put the new shock in it and all of a sudden I wasnt dragging bits on the ground, going quicker, and still had little bits of chicken strips (instead of squirmy squirelly balling right to the edge....) I actually dropped the footpeg height so it was more comfy on my knees after that cos the pegs werent decking out. Street shift pattern too

Mean. I can't wait to put the shock I bought in. I need to get some goodies for the forks first though.
