So. now I have bought one again, it appears as if the bloody things are everywhere!

Does anybody want to club together and do a deal on this stuff? Prefer Auckland based.

I dont mind the one in bits with the engine apart....

The idea would be someone buys it and we go halves and someone picks it up then ships the balance of the stuff down to me. (at my cost clearly). Probably a pallet but I would talk to Biketranz. Clearly we would need a "Who gets what and who pays what" policy but buying in bulk like this is the way forward.

Looks like a reasonable start price to me.

Start price can only be considered reasonable if u know how far from the actual wanted price it is! It is oft used as a hook for the gullible.
CB750's of this ilk - unrestored are worth about $5- $8 each. A set of pipes new OEM is worth about $2500.
I bought mine (75 rego K2) for $3500 in 2010, spent $5000 on restoration and sold it for $8500 in 2012. No profit..but got a couple of years of fun, learnt how to rebuild and got all my inputs back. It was worth $10k according to the buyer.
I think this seller will be looking for double or more the start price here.

Are Honda 750/4's the next 'big thing"?

Does the riding experience will live up to the expectation?

I'm starting to get FOMO.

It would have to sell for about 5K if new owner intended doing a full resto.

These days I think I'd rather someone else does all the work.

I rode around Aussie on a 750/4 K2 in '79. Weeping headgasket in Darwin and broke the rear subframe after hitting too many concrete cattle stops at speed (rode into Townsville with my left hand holding the rear of the bike off the rear tyre!) otherwise fine. Rode from Darwin to Perth in the days when the road near Broome was unsealed - lots of bulldust hiding potholes. The Ducati 860GTS often ran out of gas and the Moto Guzzi Le Mans caught fire after a minor spill cracked a spark plug and ignited the petrol the slopped out of the gas tank. For Aussie roads the Honda was fine, but today bikes are more powerful, lighter, smoother and handle much better (e.g. my Aprilia). Still I have lots of very fond memories from that trip and some less so (like falling asleep riding over the Nullarbor).

It's a bit late for that. It'd be a coupla years since I saw an article in a Brit mag saying that the 750s were too expensive at that stage. They recommended looking for a CB500 which would be cheaper and was, in their opinion, a better bike.

Unless you had a 750/4 when you were 16 & wanted another, in which case anything else is not a replacement.
HDC & I both paid 5k for our K2's in fair useable condition recently. I don't think that was too much at all.

I had to wash my eyes out after looking at that first one.
The fortunate part of my 750/4 was that I actually wanted a black one with flat bars & a loud four into one, just like i had in the olden days. They also come a bit cheaper than one with factory paint & pipes, so it was win win.

I too had a 750 in my yoof. My 2nd bike, after an RD350. Many fond memories chasing mates on Kawasaki 500s. Had a purple/pink lace paint job on the tank. Cooler than cool in 1976-7. Had all the good stuff - ace bars, 4:1, open carbs with stacks, Isky cam, golden rods, and honda 350/2 pistons(888cc).
I have absolutely no desire to go there again.

My 250LC I had in Perth. . . . . I would definitely go there again

I finally had a good look over the CB750 I bought. Overall not many surprises - I realised I won't be able to get the rear axle out without either removing the 4-1 or dropping the shocks which is a bit of a pain.

Does anyone know what that little sticky outy part on the swingarm pivot nut is?

It has compression (I kicked it over....) but I havent tried to start it. I know it has carb issues (according to the PO) so I am going to get some carb kits and the usual air and oil filters. It has brand new spark plugs. I dont have the gear to do a compression or leakdown test but once that is done and the thing runs I can go through the obvious..... the major issue with the bike (again, assuming it runs) appears to be the front brake... but thats OK there is a kit for that.

the only really crappy bit I have seen so far is the seat base is fucked. Usual story: rusted through and one hinge has disappeared. Easy fix there is a seat on tardme for $75 which has a good base.

Ima use my trackday spot prize of a set of Metzeler tyres to put new shoes on it.

I dont like the mismatched clocks (like David Bowie's eyes one green one blue - they should be green) but I might go for a motogadget if I can figure out how to remove the speedo drive and tacho drive....

The goal is on the road registered and WOF for next summer. We'll see, but it should be achievable because I have no intention of restoring it or anything like that. Just get it running and ride it round like a $2 hooker.

Shouldn't be too hard to whip the bottom bolts out of the rear shocks then jack the wheel enough to get the axle out, or just rachet the swingarm up to the frame to compress the shocks enough for the axle to clear the exhaust.

Does anyone know what that little sticky outy part on the swingarm pivot nut is?
Have seen a few swingarm pivots with grease nipples on the end so would suspect a lubrication point.

It looks presentable enough to be ridden as is, not everything on the planet needs to be restored, personally I like stuff in 'as found' condition. My favourite recently was a veteran truck created at some point in the distant past from a cut down tourer, has had nothing done after being extracted from a barn other than making it roadworthy.

online shopping rules. carb kits and oil and air filters from ebay and david silver.

I am dithering about an electronic ignition: I hate fiddling with contact breaker points but the ones in the bike look pretty good. The $250 p;us shipping might be better spent elsewhere

I have a battery which I can use I think.

So in terms of getting it running we've sorta kinda made a start.

If I can I would like a 1/4 turn throttle but it would need to work with the existing housing so I can retain the switches (assuming they work....).

HenryDorsetCase

18th July 2018, 22:01

Well, good news. Compressions arent too bad (130) and leakdown OK. Carbs have no main jets (which dont come with the carb kits..) so got some on order. with some intake rubbers the ones on it are hard AF and not in a good way.

Hopefully be running pretty soon.

I am dithering about the brakes. I think I want an EBC new disc and to upgrade the pads, recondition the m/cyl and fit a one piece brake line but its quite spendy.

Also dithering about the wheels. they are straight enough and look meh but since I am replacing the tyres I might pull the wheels to bits and powder coat the hubs and rims (matt black) and replace the spokes.

I am so busy that I hardly get time to work on it so progress is fucking slow.

/[/url]

I'd say the Honda was first in 68/69, first Commando to have one was the 72 Combat engined ones. After that it was the norm.

However....as people were used to drums it sounds like manufacturers were concerned about the discs being too good.

I don't know about Hondas but the Commando has a 5/8" ( 15.7mm) diameter M/C and you sleeve them down to a later 13mm.

This gives the preferred ratio of 27:1 http://www.vintagebrake.com/mastercylinder.htm.

Only thing you have to watch is final assembly to make sure the compensation port is not covered by piston or seal.

Brake will lock up over time if this happens.....don't ask how I know this.

Set of SS lines and a caliper rebuild and I think you will be surprised.

Forks you can go down the Racetech Emulator new springs or my preferred valve the Sports Valve , made here in NZ by Glyn of Ducati fame

I Googles some shit on only CB750 front brake upgrades and one common one was indeed the GL swap. It appears the main issue with the stock 750 one on a spoke wheel is caliper clearance to the spokes. I found some pretty impressive conversions.

Still, it's probably only worthwhile if it's really easy. Let's just say I don't suffer much fork-dive under heavy braking....

People seem to take a few things off the early gold wings, not sure why. They used to reckon the coils were special, I took mine off and threw them in the bin because the carbon leads were molded on and I couldn't change them (I was chasing an ignition problem), I swapped them for 500/4 coils from the wrecker :laugh:

one of the things racers used to do was swap the fork tubes out of GL1000's in to CB750's - same OD (35mm from memory) but thicker wall = less flex under braking.

Apart from that the systems are quite dissimilar: the GL has two discs and the calipers trail the forks and are two active pad sliding pin variety. The CB has a lever mounted to the front of the fork leg and one live piston and one bolted to the lever and the hydraulic line is three separate pieces from memory. Plus the disc is heavy as FUCK and thick as. I quite like the idea of this: https://carpyscaferacers.com/shop/shop-our-store/motorcycle-parts-accessories/honda-cb500-cb550-cb750-parts-upgrades/front-brake-rotor-pro-lite-sohc/

My understanding was a disk is pretty hard and doing that shit in the shed requires some dedication and a lot of beer.

I'd suspect a new, drilled, replacement disk would be cheaper than applying a labor rate and beer value to doing it yourself.

Plus if you stuff it up, you need a new disk .....

Hey so after going quiet for a while the old girl is running. It runs well and the motor is quiet (not too much of the chain slap and the camchain is quiet). Starts on the electric leg too.

I am happy enough with it from the headstock back. From ten feet away it looks pretty good but up close it look like what it is - an old bike with some form of history. I do have the tank badges ( bought from the guy I bought the seat from) so will apply them. I am waiting on a care package from David Silver Spares with some little bits and bobs and some time over Christmas. As an aside because all this shit is now collectable, its FUCKING expensive and hard to get second hand... though Malcolm at Econohonda has been good.

Because I have been so short of time Phil Parrish has done most of the heavy lifting - especially with the carb clean/rebuild and so forth. That was money very well spent.

Even with paying Phil it still only owes me around $7k? something like that - my policy is don't ask, don't tell.

From the headstock forward there is still stuff to do - the tacho does not work (cable is spinning but no one is home) but its a blue face one and needs to be a green face one anyway. The headlight bucket is cracked and the fork ears are too. I havent yet changed the fork oil but will do over Xmas. The brakes are as good as they will get with stock components and are still distinctly average. Master cylinder rebuilt, caliper rebuilt, new pads, and a new stainless steel braided (2 piece not 3) line. This is of course the key difference between old and new bikes.

Also the front wheel feels like it is out of balance so I will check that out too.

Luckily I have another bike to ride when this one is in bits again

List of parts I still need if you know of anyone with any bits in the shed:

Front mudguard complete
Fork ears left and right
Headlight bucket
Tacho
Left side sidecover small badge (red) - currently the bike has two right side badges and the left one faces backwards. It annoys me every time I see it.

I'd also like some dog leg levers - the straight ones arent span adjustable and I have small gynaecologists hands....

Ah annoying shit. I get that. Ducati for some reason rivet the vehicle ID badge to the lovely trellis frame smack on the right side of the bike in a really obvious place. Pissed me off and still does. In fact I was looking at the new V4 at Casbolts last weekend and bugger me there is one riveted to what little frame that bike has in a similar spot.

Fuck don't get me started. ...... OK - when Phil did the work on the carbs he refitted and used some thick wall black fuel line. That fuel tap has two separate outlets for two separate fuel lines (main and reserve) to two separate inlets to the fuel rail that feeds the crabs. Long story short the black fuel line would not seal to the fuel tap because the wall thickness was too much between the outlet and fuel tap. Most modern fuel line is really thick wall and reinforced because modern vehicles are fuel injected. Anyway, the solution to "thin wall, flexible fuel safe line" is TYGON brand fuel line with matching clamps - which is that bright yellow stuff. Sourced from the Kart Store on Brougham Street after much googling. $15 a metre retail.

Also I pulled the fuel tap to bits to make sure the internal filter was clear and it leaks when put back together - oh, and the O ring to seal it appears to be some sort of proprietary part. I have one (and a new fuel tap) in my care package from David Silver. All part of the fun.

Good point. That thought hadn’t occurred to me, but HDC is wanting a twenty first century nicety for a twentieth century bike.

On checking the CRG web page they say they do levers for most modern sports bikes. I guess the job is possible but it might not be a simple fix.

When I were a lad, the hot fix was "dog leg" levers - thats actually what I want. Span adjustable would be no good on this bike because you need to grab the thing with a hearty four finger grip and squeeze like a 13 year old who's just discovered masturbation.

Apart from EMGO, this crowd seems to do what I want: http://www.flandersco.com/Products.html Plus, their website is from about the mid 70's.

the levers arent a priority just a "nice to have" - the priority is investigating the front end.

went for a pootle today and I was like "Not loving that thud from the front..... must have lost a wheel weight". Yeah, not so much. The front rim is quite a long way out of true. If it needs a rebuild I will get someone to do it. I also decided to have a wee look at the forks. Big mistake.

Having said that the chrome sealing surface isnt too bad and they werent leaking. I think I will just clean them, put some paint on the really rusty bits and move on.

Hardest part was getting the top circlip out because it had sort of rusted into place. Icky

Henry just a thought
340167
I just brought some forks of a MG California these are 45mm and have adjustable damping comp and rebound
They are likely way to big for what i want and likely far to long and the spacing to wide
But they are perfect for what you have.
i mentioned earlier the 320mm brembo discs fit on your honda hub.I have one of the Brembos goldlines same as 748/916 etc, Pretty sure Kickaha has the other side. but these are pretty generic anyway 65mm mounts
The guy i brought them from said the tubes are pitted but the damage appears to be at the top which would be covered by the headlight.
I cant comment as i havent seen them yet.
The new tubes for these are $200USD each
edit loking at the chart even though honda have poxy small od front bearings and a small axel. 20mm axel on guzzi still only needs a bearing change 6002 to work with honda hub.

Easy stuff shouldnt be hard. I went to drop the oil out of it yesterday (doing it arse backwards as usual) - in fairness the oil didnt look too bad but I had bought a filter so I thought why not. No crush washers under either the oil tank drain or the sump plug drain... not even a flat copper washer. Oh, and the sump drain should be M12 x 1.5 x 12 long. Its some random UNF bolt cut to size. I suspect a PO has stripped it and just wound a bigger diameter bolt in there rather than helicoiling it. If it seals up with a copper washer I will leave it. If it doesnt I will do it properly.

Oh, and that front wheel? Radial and axial runout are OK (not quite within spec but not far). The fucking tyre has the runout. Either it isnt up in the bead lock or, errrrrr, something.

85psi on an inner tube is a bit scary. Hopefully you bought a decent brand and not cheap junk.

How big is the tyre and what size rim? Probably 1.85. Written (stamped) on it.

We spent waay too much time in the 90s trying to bead 85 section slicks onto 1.6" RG50 front rims. Down, up, lube, debead, move tyre, reposition inner tube valve reinforced section, down, up, repeat.

Dam that seat looks comfortable - clearly not Italian!

Looking good, what's it running on the exhaust and aftermarket 4-1? I'm trying to remember the NZ brand back when I was a young chap - Sagar (or similar) springs to mind.

Seat's not bad - the foam is 40 + years old so its a bit crumbly. I've got an aftermarket complete seat base which I am going to get re-covered.

There are no makers marks on the pipe at all I can see. It is quiet as though so has some baffles. There is a MAC 4-1 on tardme which has been for sale for a year at $450. I might pick it up at some point.

Priority is that fucking front wheel and a front guard, then some clocks and fork ears. Malcolm from econohonda has a set of blue face clocks with the patina I want on tardme but they are mph, and he wants two fiddy for them. TWO FIDDY!

HDC you mentioned a bead lock does it actually have one on the front wheel as that was rare for road bikes?

Also what Kick is saying what does the tyre look like down by the rim edge? Sometimes the tube can be stuck under the bead and push the tyre out a bit at that point.

Voltaire

26th March 2019, 10:04

I do my own tube tyres these days as the apprentices tend to put the tube in straight out of the packet whereas I put some air in to avoid pinching and overlapping which can cause rubbing and flats.

let the tyre down, massage it with your hands and reinflate. Sometimes they stick at a point and don't pop onto the flange.

Cor, well was thinking of this thread as I was squeezing what I reckon is a too wide tyre on the GSXR400. It's what size came off and size down from what the internerd sez but fuk it it'll likely never lean past 20degrees with the owner commuting. Once on looked ok. But wasn't beaded. Hence thinking of this thread.

40psi run out of air and no bead. Oh great. Here we go. It had taken me a full hour to debead the 20year since last used tyre. No kidding. Vice for the win, followed by shovel.

I have one similar but hooks under the Van towbar. I call it the Biddleiser named after a mate that had one I coppied. Works everytime you aren't fighting a tyre that has been on for over a decade. Quantum difference.

Got home early and did the front. More vice/crc/shovel. Balanced up a little more difficult than the rear but should be ok now. Beaded at 40psi so that was a relief.

All made harder by Jerry rigged bike stands. Shit my race and even road stuff is so much easier with proper mounting points. Modified my front stand to fit.

We used to use rubber grease to seat the ATV tires. iI would like to think it helped seal up the air until it popped on. Atv ones were always harder to de-bead as well as bead, We mostly used to use the tire company hydraulic de-beader for them. One of the places were i worked had a homemade one like in the picture, but it didn't tend to work on the ATVs. i never used anything more than dish liquid at home for motorbikes, more often nothing, just a bit of talc on the tube.

Funny you should ask Gaz, since I've had the VFR I've always let the shop do its tyres, but I'd usually done trail bike tyres myself and they've all been tubed tyres.

Bugger me though last week I needed a new tyre to be put on my Honda XR250L. In the old days we rode XL and then XR Hondas that were really dirt models on the street. The L model I now have you'd call a dual purpose I suppose and they've got all safety conscious so steel petrol tank instead of plastic etc and DOT standard road/trail tyres. Well I take off the back wheel and tackle getting the tyre off and talk about a stiff carcass tyre. It has been a good tyre plenty of grip on road and trail - it was OEM Dunlop. Broke the bead alright but it was a bit of a mission after that but I at least got it off.

The tyre I replaced it with was a Pirelli MT21 Rallycross tyre, again dual purpose rated, but for the life of me I could not get the damn thing started onto the rim the carcass of the tyre was so stiff. So after much levering and buggering around I took it to TSS and let them put it on for me with the machine. $30 well spent. Perhaps we are just getting too old and weak to do these jobs lol :eek:

Old bikes are hilarious.

Yes, some of the answers you receive, are...

I'd simply lift the tank and check what's happened to the throttle cables. Could well be as simple as a cable fallen out of it's stop - or the idle adjuster wound itself out...Or one of the links in a carb come loose. Best I saw was an idle mixture adjuster screw had fallen out of one carb and that one was lean and dragging everything up. Owner came to me and asked "why is this plug white ?"

HenryDorsetCase

29th April 2019, 12:32

Trouble with old bikes is all the parts are going to fail at different times.
Intake manifold rubbers harden with age/heat.
Probably a good time to rebuild the carbs with new seals and gaskets, new fuel lines, rebuild fuel taps.
Throttle and clutch cables.
Have you overhauled the brake hydraulics?
If its got points fit new ones and condensers, maybe even coils and leads.
Or spring the 18K for that 1100/4 and just ride :laugh:

You can get a good selection of cheap compact tools to put under the seat which I like to have to hand.

Its had new intake manifold rubbers, new carb to airbox rubbers, full new carb kits including new emulsion tubes and main jets, new fuel lines with filters and a new fuel tap (the old one would not stop leaking and I finally got sick of it dribbling after I had rebuilt it twice - new one keeps its fuel on the inside).

It has new A and B throttle cables and a new clutch cable.... but yeah its time to check all that shit again.

$18k for the lookalike is sounding pretty good right about now.

I can't do anything with it till I get rid of an HD Street 500 that belongs to a mate - it needs a new battery which involves quite a bit more fuckery than I was expecting (because it has to come out the side due to the low seat height....). Still, its nice weather to be in the shed.

I like the painted floor, and have access to a reasonable quantity of 2 pack paint, but that would mean clearing everything out of the garage to clean and paint.....

A bit of carpet in front of the work bench is nicer than standing on concrete, if there's anything too messy to do it happens at the other end of the garage, mine is lovely pinkish coloured rubber backed commercial carpet tiles. Works well, when I spill something on them I just pick up the dead one and replace it.

Don't have a garage anymore, think yourself lucky ya bastard. Bike probably over revving because of your limp wrist basketcase. 😇

The CycleX (or there is an ebay seller out of Vietnam) seem to be the go. The interesting thing about those gauges is that the guages, forks (stanchions and lowers) brake arms and calipers and front guards are where the subtle differences are. There's a reason he says "1973 and up"... before that the gauge mount plate has a pointy thing up the middle and sits higher. The gauges mount with a metal strap about 2/3rds of the way up the body of the gauge. Its specific to K1 and K2. K0 and CB750 had a similar setup (I think) but they had the idiot lights inside the gauges themselves. Mine has the little four idiot lights between the handlebar clamps which they continued till they put the ignition key up there as well - not sure exactly when but my F1 had it and I think maybe K6?

Actually, an anorak like you will love this shit too. If you look up my engine number and frame number on the sites that tell you what model you have (and thus what parts will fit) my bike is registered as a 1974 CB750K4. The motor corresponds to that but my frame number corresponds to "early" K2 - so I have K1/early K2 gauges, stanchions, fork ears, fork lowers and front guard. According to other owners and one of the forums I'm on, this was standard for Her Majesties southern colonies..... which seems right as my engine is the stock engine in the bike as far as I can tell.

That became important when I paid $500 for a mint condition K2 front guard for my bike in a bidding war frenzy on tardme. You got it, it don't fit my forks.

Basically everything pretty much from late K2 through K6/K7 is the same but the differences are in the early models as they standardised.

We wont even get into the "sandcast" K0 differences but there are a lot of subtle and not so subtle differences.......

The evolution of changes in long term production isn't just a Honda thing - but it's more noticeable there as the CB750 went on longer than most.
At least they were prepared to invest in new tooling and small redesigns during the production run. The Brits couldn't afford that so the later parts are from the parent factory, the less likely they are to fit properly. The tooling was worn out.

well, every time I see one of these on tardme I feel better about my one.

Oh shit. Based in that, I've just offered my k2 to a gentleman at a bargain price now I have the F1.
Ahh well, no regerts.

Heres a stupid bit of anorak
The K1 front hub is 4mm thinner than the K0
the K4 is different from the K3 due to different pinstripes
the CB750K6 of 76 which was a four piper for those that didnt like the F1 styling they changed the bolts on the top yoke from 8mm to 7mm.
the sand-casts have a different number of bolts on the clutch cover 10 instead of 11
the K7s had a 17 inch rear wheel and and a O ring chain.

Thought I'd add this supplier to the thread.
Was a bit hard to find due to the name, but prices are some of the lowest I've seen anywhere so far.

Just had a browse. Good contact!
Wow, they must be the only people in the world not trying to cash in on the scarcity value.
Useful stuff at very reasonable prices. I could go broke saving money here :laugh:

I've been really enjoying my F1, finding it to be just the right amount of classic.
My '60's BMW is a very antique ride & my two '80's GSXR's are almost a fully modern ride with 4 piston brakes & monoshock until you really start pushing.
The old Honda requires a bit of effort & forethought, it can get along great, & makes for fun & fast at not far above the speed limit.
You also don't have to ride it all day to feel like you've done enough, as the rewards for a job well done come thick & fast.

Any of you CB750 owners been through the carbs - and got the old bits sitting on a shelf ?

We're reviving a roadrace sidecar which uses CB750 carbs but ran on alky. The needles have been hand massaged - as you did then - to suit alcohol fuel.

I'd like to find a set of petrol needles - year irrelevant.

Thanks.

the beatty of most of these are they tell you what fits what and also what bearing size, spoke length and rim width etc.
they also let you see what often fits what between the years.
