MVX250 resto thread

[White trash]

Freddie, all the way... get a different tail end and modife it with two pipes in it and make a spanny to hang under... cool

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

You going to get a seat cowl for the MVX also like this ?

(BTW never seen this colour scheme before on the attached pic..)

He could make one out of an icecream container I reckon. They are just a box that screws to the seat.

(BTW never seen this colour scheme before on the attached pic..)

They came in three different colour schemes, white with red and blue, red with black, and whit with two tone blue.

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

If WT doesn't know... or cannot help.. i would LOVE to take it off your hands..lol

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

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

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
