MVX250 resto thread

[White trash]

Righto,

Drew managed to get hold of a horible old MVX250 Honda for my birthday 'cause he knows I love em to bits and have always wanted to restore one. RDJase kindly supplied and towed the bike to Manfeild a few weeks back and the exchange was done.

Here's the pics. Over the next six months I plan to return it to it's former glory. If anyone knows of any bits lying around I'd be interested to hear. In particular after the R/H raadiator shroud.

Stripping commences this weekend, more pics of the progress to follow.

I have a radiator and the original mirrors off it , I will drop them off to Drew at Rd5,

And just for the record I never owned it, it follow me home like a lost dog Its good its found a good home now tho, even tho Roadracingoldfart wanted it shot:bleh:

Love the pic of Drew, I know he wants to race it:clap:

[nosebleed]

Woohoo, the MVX.

Mine made a 2-stroke mechanic out of me.

[White trash]

Shit yeah, nothing better than doing rear cylinder rebuilds at the side of the road. Roadracingoldfart used to race one back in the day, that's how old he is.

While it was parked up at Manfeild, I'd say it drew more attention than any other bike in the pits.

[hospitalfood]

see if the engine #'s go with the frame #'s. if they don't it may be one of my old bikes. i blew the original engine in Petone and swapped the engine over in an upstairs flat in Hopper St, Wellington after getting another one for parts ( a blue gray one ).

if it is my old one, cool !
used to do Welli to Aucks and back in the early 90's in the weekends to visit my son. I remember the lights dimming and cutting out one night every time I went over 140 odd km/h in top gear.

[Pwalo]

Don't do it. It'll only end in tears! There is a reason Honda stopped building those things.

[T.W.R]

I know where there are two complete bikes, both suffering the infamous seizure problems but the bodywork is complete on both.
They're a wee ways away from your neck of the woods though....but I could ask for you if you're interested.

[Max Headroom]

We musta done something wrong then . . . . .

My wife rode an MVX250 back in the late '80s for a few years. It was a low owner, low mileage bike which had been looked after very well. It never gave any problems with rear cylinder seizure.

The only trouble it gave was the result of running it on cheap 2-stroke oil for a few weeks, when it holed a front piston crown. I bought a new piston & second hand barrel, and swapped them over. Too easy.

It was a brilliant little bike. My wife eventually replaced it with an RG400 that subsequently almost killed her, but that's another story . . . . .;)

[F5 Dave]

They were such a running joke back in the day I remember going past Sawyers in the school bus & they were virtually giving them away with any bike sold (or 4l oil pack).

But in the end they've kinda turned retro cool, bit like owning a, um, well one of those. But cool & good on ya.

There is all sorts of lore about those, one being that the timing is off & needs to be dial gauged & the pulsar retarded on the rear. Who know if that is myth/pub story, but it couldn't hurt.

[Str8 Jacket]

Awesome! I was a little jealous when I saw it at the track...

Can I blow it up for you when you're sick of it, please?

[SPman]

Cooooool.....Ive got a mate over here looking for one - to go with his NS400R, 2x RZ500's, RG500, KR250......etc....etc......

My last one was really good actually, I did MEGA miles on it as did my dad. They're actually really nice bikes to ride. Very comfy, awesomely smooth. Not very fast though.

You know how one goes about that?

[dangerous]

WICKED SHIT
loven it WT... cool and a very misunderstood bike. Yeah factory timing was off, jetting was out all ending up with holled pistons, running a colder plug in the rear was all we knew about the bikes due to the rear not getting the same cooling as the front two, but in fact as I found each pot would take a turn at holling.
There was a after market piston high domed/compression cant remember the brand but they did well, and once fitted up the bike lasted forever... ish

excuse the quality of the pic it was back in the 80's

ps: Drew seen a modle of mine at home and stared at it saying Jimmie would cream himself over that.. we loughed :lol:

[T.W.R]

Hey if you could ask the question I'd be most appreciative. I can freight anything anywhere :)

I'll get in touch with him & see what he's upto with them...... last time I was talking with him he had plans of rebuilding one with the idea of using CR85 pistons etc. He's got about 6 bikes in various stages of repair so I'd say the MVXs will still be the same as last time I saw them.
Once i findout I'll let you know :niceone:

[F5 Dave]

You know how one goes about that?

Well first thing to do would be start at first principles & put a degree wheel on the flywheel (very cheap large protractor) using an extra nut with bolts to affix it to the crank end if there is enough thread poking out. Make a thin wire pointer line up to the marks on the wheel.

Then a dial gauge in the spark holes would find TDC for one set of pistons. Then wind it on to TDC for the rear piston & presumably that should align at 90 degrees to the front two (they are 90 deg aren't they?) If it is out by a few degrees then the crank wasn't assembled correctly.

Having not seen an MVX ignition set up I will continue with assumption;
Presumably the ignition fire is taken off the flywheel by an internal or external pulsar coil. There will be two, one for each bank of cylinders positioned at 90 degrees away from each other. If you want to retard the rear one; slot it's mounting hole & rotate it say a mm or two in the direction the flywheel rotates. This will retard the ignition giving that cylinder an easier time. The coil should remain same distance away from raised bit or the flywheel will clout it, or not work if too far away.

You can work out which cylinder lines up with which pulsar coil as it reaches TDC it will line up with the F (Fire) then T (top) mark on the flywheel & there will be a raised section passing under the related pulsar coil then. If performance falls off notably you could wind it back a little, there should be a sweet spot.

I'd also check that the fuel supply is ok to all carbs, watch fuel filters which can be hidden in carbs or taps. Make sure carb jets cleaned out, 2 strokes often seize on closed throttle meaning pilot jet. You could try wind the idle mixture screw in a touch more than the other cylinders which will richen the mixture a tickle.

[White trash]

Legend Dave, thanks for that. Fancy a wee trip to Auckland? :)

Nah I'll be able to work it out from that explanation.

[nudemetalz]

I'd love an MVX.
Mate had one back in '87 when I had a CBX400F. We used to dragrace down the Auckland Motorway (we were 17 yrs old afterall), wasn't much in it. I rode the MVX and got 160km/h indicated (on private property of course ;) ) on it. Remember it being smooth motor with a peculiar flat engine note.

Pity Honda never developed it into a 3 cylinder NS250 based on the '400.

[dangerous]

Yeah a trip is very smooth and the V3 super smooth... engine note was one of a kind sounded awesome with oil dribling out of the rubber boots on the tail piece.

Ya have to remember the MVX was brought out over night as Suzuki had relised the RG the RZ arived and so had the KR... a bit slow of the take was Honda but hey not a bad effort even tho they should have knowen beter.

check it out both the MVX and RG were the only two fully faired bikes (RG & MVX) in the contry at that time the Rg was x top racers of the area and the MVX was a x well knowen rider at the time aswell.

[gwigs]

My sons bike,it goes but has a crankshaft seal problem and need forks and brakes done...I might do it up as a project .Parts seem to be hard to find though I have seen plenty on Yahoo Japan but not being able to speak or read Japanese it aint much use.

Yup... All that oil down the pipes and over the floor.....

Yes, Honda should have known better.... Realistically they just wedged a V3 into a VT 250 frame....

Oh, and the power... Well it was plenty for a 17 year old with stuff all road experience.

[quickbuck]

Two things here .......

1 You stole my photo ya bastard (the one with the missing middle link in it )
2 Im starting to look on this beastly bike with a bit more respect than i did when i raced them. Assholes like Holden , Mcdoanld and others all blew me away but i had soooo much fun getting in thier way but i never got lapped once in 2 years ,thank god for short races lol. Free bikes were always good bikes:2thumbsup and when the NS400 r came out i never touched the MVX again.
Ill give you a few tips some time Jimmy . One thing they need is a reliable clutch lever , just in case :lol:

I will watch this thread with interest :pinch:

Paul.

[roadracingoldfart]

Its good its found a good home now tho, even tho Roadracingoldfart wanted it shot:bleh:




Its true , this is all your bloody fault , all you had to do was pull one little trigger , your a bloody failure.

[geoffm]

Hm the MVX handgrenade (pin optional...)
A friend ahd 3 of them - but only 1 running at a time as they all blew up.
There is an english language workshop manual, which any MVX owner will soon learn off by heart. No copy in my archives tho.

If this bike ever gets on the track i may have to buy an old RD 200 electric to give Trashie a thrashie.

Pfft, whatever old man. It will make it to a track but only in track day capacity, I'm over racing.

Got some good suspension mods in mind to lessen the softness a bit and a few reliability fixes. She'll be a good un.

[Taz]

Inboard ventilated discs were honda's answer to a a question nobody asked :)

[vifferman]

What an "interesting" bike. :confused:
Good luck with it, Mr Trash, Sir! :niceone:

[Ixion]

Could you not find a cheaper way of causing yourself intense pain and loss of sanity?

Maybe putting your head into the blades of an industrial lawn mower , or wood chipping machine? Something like that?

[F5 Dave]

Inboard ventilated discs were honda's answer to a a question nobody asked :)

Well the question was originally why don't my brakes work in the wet?, Answer 'cause you used stainless discs instead of iron like the Ities. Only thing is that; by 1983 people had sintered pads so, it was no longer a problem.

In the end they weren't such a bad thing for a roadbike, . . . I'm not saying they were a good thing, -but they weren't as heavy as people made them out to be & once you worked out how to take them apart it was almost as quick as a normal wheel to remove. Some people had problems, but only 'cause they weren't thinking. Never heard of any inboard discs warping or wearing out, which is more than can be said of a lot of bikes.

[malcy25]

Never heard of any inboard discs warping or wearing out, which is more than can be said of a lot of bikes.

is that because the bikes theyw ere fitted to were never running long enough....!:whistle:

[F5 Dave]

My CBX550 had 96,000 on it when I sold it having done 60k of them myself in the late 80s. Don't get me wrong I'm hardly a Honda fan, they had their fair share of Turkeys. But poke fun where it is due.

As a kid we used to deride a couple of bicycles, one for their advanced gear shift technology as it was reputed that the cables can break easier. & another for some dumb arse reason. All I am saying if I am honest we were speaking out of ignorance & urban myth. The public are very fickle. In England the TL thou became a monster killer bike, but it was no where near that bad. Some bikes had glaring faults & could be fixed, but once tarnished it is hard to overcome. The VF range became the VFR after multiple problems & only Honda stubbornness kept the range going.

. . . Now CX500s, they were shit.:lol:

[jellywrestler]

these were an interesting bike, from memory they were $3454 new and the RZ was $44?? and the RG was $5454 which when you look at the three brands of 250s on the market with a full $1000 between them and the suzuki more than 50% dearer than the honda it must have been an interesting life for the salesman.
I recall too that NZ was one of the few markets to get them and word was it that honda made them, found out that they couldn't even pull the skin off a rice pudding and were going to divert them to the crusher until blue wing got in on them?
any truth to that rumour???

[dangerous]

. . . Now CX500s, they were shit.:lol:

HEY WAIT JUST A MOMENT... what ya mean 'shit' from my worked B to the TC 5 in all I never had any probs and thats including riding one from Nelson to Chch in the red (temp) due to a blowen water pump at over 160kph and all I did to it was warp the rear casing... well ok the pump seal went but hey, LOL :2thumbsup

[quickbuck]

. One thing they need is a reliable clutch lever , just in case :lol:




Hmmmm there were only two things that broke on mine........
Yup.. piston broke.... and the clutch cable....
Not at the same time thankfully.

Yes, that's pretty much it.
I had a RG250 at the time the MVX was released, I rode one (MVX) on makara rd and thought, hmm, when is it going to hit the power band, then I looked down and saw I was already red lining it :lol:

[roadracingoldfart]

is that because the bikes theyw ere fitted to were never running long enough....!:whistle:


Bollocks , i raced a CBX 550 in the Castrol 6 hour and we did the whole race on one set of pads and thats a fact.

Inboard rotors were a very tricky bit of Honda's bikes in the day and they were fitted to many models in various guises.
Once you worked out how they worked, what to maintain and how they came aprt 9and back together ) they were great , but they did make a bit of a mess of the rims because of the material they used. They were better in the wet than exposed rotors as well.

Rant over ...... as you were.

[roadracingoldfart]

Yes, that's pretty much it.

Agreed. Only because I have one mind you. Probably smokes more than an MVX too. Something to do with having character or some such thing.

Na no way, Iv had 5 of them from the A to the TC from 2,000km to well over 100,000km never done a cam chain never heard of them being done. (honda did have issues with other modles when they introduced the auto tensioner)

anyway... this is about the MVX a real misunderstood shitter that you either love or hate, someone mentioned the bland power delivery for a wee stroker... well the NSR 400 another V3 was much the same, typical of Honda and their erganomics.

[White trash]

Well not much has happened recently, mostly due to an impending birth and having the girls up for the school holidays.

However, having spoken to a dude on the phone last night who's as enthusiastic (read mental) about them as me, I'm all motivated again. This guy's got a running riding MVX also so I'm racing to get mine roadworthy before the end of the summer so we can meet up at a pub and go for a hoon.

So forks and shock will be off to Dr Bob this week for some fine tuning.

Frame will be stripped and repainted to its former glory hopefully in Feb then reassembled and hit the road :D

Pics to follow.

[nudemetalz]

Wonder if an NS400R engine would go in one. That would make a surprise for the RGV boys !!

[F5 Dave]

Don't put him off track, he's easily distracted. Besides might as well leave one in the 400 if you have one. When was the last time you saw an RGV on the road to 'surprise'?

Did drew get those throttle cables, mirrors and rad to you?
I have been asking around for parts, after they stop laughing and metioning rear cylinders you get the "MVX Stories" Hope some bits turn up in forgoten at the back of the shed dusty parts

Are early VT250 plastics the same?

The engine sounds mint , not a rattle in it, I got it running after cleaning out the carbs , hot wired it (key missing) and 1 half hearted kick and away it went, was quite suprised how easy it started as it had been left out side for years without even being kicked over.
They have definatly got a sound of there own

The motor's good however if I find I need parts I've found a nutter with a stash of pistons and other new parts he'll ration out to worthy causes. He thought he had the last running one in the world. Can't for the life of me find that fucken R/H radiator shroud and it's pissing me off.

He also confirmed your theory on the ignition timing Dave.

MVX FTW bro!!!! Cheers on the front rotor mate, much obliged. Drew dropped all the parts off on new year, she's coming together well. There's subtle differences in the VT bits too unfortunately. I almost have everything I need to make it mint again now anyway.

If I had an NS400 I'd probably be more inclined to keep the motor in it as they're a far sportier chasis than the MVX anyway. Ignition timing theory confirmed too Dave, thanks for the heads up.

[F5 Dave]

Well it looks like you'll be lernin sum new skill with fibreglass reproduction if you can prise a shroud out of your nutter to copy.

I was thinking the same thing mate. LOL I shouldn't call him a nutter because he's a bloody top bloke with heaps of advice to offer. Just can't think of any better word to describe us few remaining MVX-ophiles....

If I had an NS400 I'd probably be more inclined to keep the motor in it as they're a far sportier chasis than the MVX anyway.


I was talkin to a mate who reminded me of days gone recently , we did 1m19s round Manfeild on the NS400R and 1m 25s on the MVX250s so they had some go . If the clutch wasnt half way in all the time out of fear they could have gone better lol.

As a comparo , the CBR600 was good for 1m 17s (others were much faster) .
I seem to remember the MVX lasted longer with rich jetting on the track than they did on the road as std jetting anyhow, and they still pulled ok.

Paul.

[quickbuck]

Heck.... Some sharp times there Paul...... Especially on the suspension the MVX has.....

My LC has only had 3 rides home on trailers in 17 years, 2 crashes and once it threw a chain (while trashing it down the river)

This classic 2 stroke ride could be lots of fun, Dont see many about any more. At the bikoi I saw 1 LC , 1 TZR and 1 RZ(tyger tung's) Not even a RGV or any older stuff,

You will find the manuals in the heads of the old fukers like me, loaded it in there when we were teenagers and pulling trhe MVX's apart, actually we never used a manual, rip it open and shove it back togeather... no worries its a stroker, wasent like we didnt get enough pratice :Oops:

Ok, seen as the closet MVX quears seem to be comming out, Ill admit I have one already Drew has seen it and the funny thing is when he did his words were "fuck Jimmy would be creaming himself over that"

[Scotty595]

More people seem to look here than my thread so will ask here -

I have been told by the guy i bought it off it needs new clutch plates, the clutch lever has no resistance/spring back at all.

He said that it uses the same clutch plates as a Honda CR250, can anyone confirm/deny this? Either that or tell me where to get clutch plates from?

I always wanted an MVX as a kid. Nice to see some fine looking examples still around today. Must be tough getting parts for them :shit:

[White trash]

Been a bit quiet lately but really need to give a huge thanks to the guys at NZ Soda Blasting in Montgomery Cres, Upper Hutt http://www.nzsodablasting.co.nz/index.php/contacts-locations/wellington

4 days from drop off to pick-up, media blasted, powder coated, cleared, ready to roll. The job is FANTASTIC and well under budget.

I'll post some pics when I get home, now I can start the reassembly process, well on track for an early Feb start up.

[White trash]

Well in a fit of enthusiasm, I began reassembly yesterday. I'll probably do a shitload more today judging by the weather.

Here's the bare frame and swingarm post powdercoating.227225

I promise to not use a phone to take images again. Anyway, swingarm, linkages and shock are all refitted. Amazing how long it takes when you're cleaning and repainting everything as you go. Looks fucken good though.

I'm off out to the garage again soon so I'll get some more pics as I go.

This week has been most productive in getting the old bitch back to rideable. Last night I decided to do some work on the forks so that as soon as the steering head bearings arrive, I can get the wheels on it and sit there making vroom vroom noises like F5dave can.

So, in typical Trash style, I charge into the job. Strip the first one, carefully clean up the tube. Chuck new seals in it, oil level perfect, bolt it all back together. Mint! Grab the second fork, lay it on the bench as as I'm spinning the tube in the leg to wipe the crap off it, I notice there's easily a visible 10mm of run out in the top of the tube. CUNT! Fearing the worst I grab my newly completed "mint" fork, and not actually wanting to check slowly rotate that tube. Yup. Two bent forks.

Rookie rookie rookie.........

[Paul in NZ]

Yup. Two bent forks..........

Mate - thats not a fault, its a feature, adjustable steering geometery :innocent:

10mm is quite a bit... Are they thick walled enough to stand a straighten out?

The thought crossed my mind briefly @ midnight but then I slapped myself into reality and reminded my bourbon soaked brain I'd promised to do this one right.

I've got a complete other bike in Christchurch which I'll get Bike Tranz to collect next week and get it up. Hopefully, those forks are straight. Just means two more weeks before the wheels can go on it.

There is a fella in Cambridge who could straighten those forks no problem

Dude, at what he's asking it's just too expensive for us unfortunately. I just bought a complete, full bodywork, (sad) runner for $180.

If your man's interested, we might be keen on buying some bits and pieces, but realistically I wouldn't want to pay more than 500 for the collection.

Loving this thread as it brings back memories of my MVX bought brand new in 1983 from a dealer in Adelaide, SA OZ

Never had a problem with mine and always ran hotter plugs than standard, I think they were NGK gold from memory and used good two stroke oil.

Used to travel 80km round trip to and from work on the chain of ponds road in the Adelaide Hills and she was superb to ride :yes:

May even look for another to rebuild here in Oz one day

Well, spent the last few days doing my my best to get all the engine cases cleaned and repainted in a colour and finish I'm happy with. I can get a mint finnish in Matt but semi gloss black is proving difficult. So I've grudgingly decided that I'll make do with how it looks for now, and once I get the spare bike up here I'll completely strip the cases for soda blasting and new HPC or similar. Then a ground up rebuild of the fresh cases.

Anyway, now the motor is fitted the engine covers actually dont look too bad and will be OK untill the new motor's ready.

On to the pipes and cooling system next.

While the idea is sound, I want it to be orginal like the MVX. Maybe If I find another one later I'll make a hot rod out of it. But if I won Lotto I'd just buy one of the original NS500s and roost the pre-89 senior field :D

Nah mate, not keen on the tail section to be honest. There's a dude in Singapore that seems to have aquired almost all the worlds NOS MVX parts and he's got quite a few of the Blue and White panels available. Sadly, he wants absolutely stupid money for all his parts.

I have just been offered a complete mvx , in good nick , but with no spark ( one way of stopping piston siezures ) for $00.00. Does anyone have any theorys on why they ( reputidly ) sieze the middle pot. Have modern 2 stroke oils helped at all?
Im thinkin that being water cooled there shouldnt be a temp issue with only one pot (???)I get the feeling that running a colder plug and/or retarding the spark in the rear pot are really just going around the real problem rather that solving it

I have just been offered a complete mvx , in good nick , but with no spark ( one way of stopping piston siezures ) for $00.00. Does anyone have any theorys on why they ( reputidly ) sieze the middle pot. Have modern 2 stroke oils helped at all?
Im thinkin that being water cooled there shouldnt be a temp issue with only one pot (???)I get the feeling that running a colder plug and/or retarding the spark in the rear pot are really just going around the real problem rather that solving it

Cold plugs don't do shit. I've richened mine a tad, ignition advance seemed to be all good. Running B9ES plugs all round, slightly richer on the middle pilot and main, and running decent oil. Check the oil pump for any dramas too, iv'e got mine slightly higher set than std too. Good oil means it doesn't dribble oil like I remember. Best bet is simply not to ride it :D

Now this is a pic I had from the 1984 Lyall Bay races and hadn't labelled it so who was number 106 on the MVX?

It's not Martindale is it? And why are they sitting on the rear seat? Weird.......

Well as a refresher and to my best of knolage... Honda never set the timing up correct, adding a aftermarket progamable unit should help, possible ran on the lean side ex factory and same with the oil, other wise beter oils and cooling these days should help, and in my experance it wasent just the rear, it went more like rear left rear right rear left rear right...
NB: remember extra oil in the mix can also lean the mix so to richen the air mix should be done

sitting on the rear seat

it's a honda. no other comment required.

Good price for the MVX !

At the start of this thread there is ignition info and set up advice to stop engines problems.
Jimmy onto it and do what he says and it will be all good

They have 2 CDI/Igniter boxes, has your one got no spark? or just lost one or two cylinders? You wouldnt think 2 CDI's would shit themselves.

It might be something easy :cool:

You can kick an MVX all day, but if it's got a flat battery it won't spark no matter how good the charging system is.

Perhaps chuck some jumper leads on and check it out.

Dumb fuckin Hondas!

LC and RZ are good like that that since there Mag CDI and dont run off a battery, all the battery does on a RZ is the YPVS servo motor

I remember to to get Jimmys bike going I run my LC's battery to power the CDI/Igniter box, sparked straight away

Then you go fit a programable ign like a Zeeltronics & you need volts to get going or you can kick till the cows come. Dumb progress.

Same thing with the Ignitech I got for my 90 degree crank, it and all the other bits are waiting patiently in a box.

[Desmo guzzi]

Thanks for the tips guys . I havn't even had a look see yet ( feining disinterest), but the owner has hooked up another battery so the no volts thing might go somewhere, electrix I can do but I already have a pretty comprehensive collection of fucked pistons, even some in matching sets , and I dont want to add to it, so all tips are appreciated , can anyone reccomend a manual for it
Thanks

Sounds totally fucked, don't touch it. I'll take it off your hands for a box of Heinekin. You're welcome.

[F5 Dave]

I think I'd rather have the MVX. I did have some Heinekin left at my place, I had to give that away too.

[White trash]

Lol. In response to the "Hyo" tags down the bottom. I had an inpromptu (sp) drag race with a 2011 Hyo GT250R a couple of weeks ago from the lights on the Hutt Road. After (literally) smoking the young fella, he pulls up next to me at the next lights and yells, "Dude, I think there's something wrong with your bike, it's smoking like hell!" Wont name names but it sounds like some young fellas have never heard of a two stroke. eh Emilio? :D

[Desmo guzzi]

Sorry WT , I may have misled you ,whilst I do have a truly awesome fucked piston collection ,all are from previous (umm, ah , lets call them ) "experiances" none are MVX ones.....................................yet:niceo ne:

All good mate, I look forward to seeing another MVX being returned to its former glory and hopefully getting a few running ones in one place at one time.

What a fucking comedian :rolleyes:

haha... good read man, poor old VF750 being picked on again as for the CBX550, kinda think it was all auto tensinors of that area, but like the VF it was an easy fix, so not a biggie :shutup:

[F5 Dave]

Well it was the Honda auto tensioners of that era. Didn't get that problem on a Suzuki or a Yamaha. Maybe a mid weight Kawi,. . . but every bleeding 'orrible 'onda.

Well the thing is now in my garage, and I have a honda w/shop manual for it ........ let the dissapointment begin .

Good luck !!

Good luck !!There is only one criteria for a "reasonable" MVX. Does it run on three? If no, the project is completely academic I'm afraid.

Don't run it too long without baffles in the pipes by the way. Bleeding off too much from the expansion chambers can cause lean running according to the 2 stroke tuning bible I have here.

I'm looking for an oil pump for one if you got one ,might be needing a few other bits also

[SouthCantMan]

Finally dragging the MVX250 out of the workshop corner and have stripped it done to start restoration.

Always on the lookout for parts or affordable complete bikes because hoarding is what I know


Also restoring an old MOT CB650.

Please message me if you have any of the above.

Thanks :-)
