hi all,i bort a ypvs mota many moons ago,and im now thinking of making a project of it.the bottom end is marked 1wt,the barrels are marked 1ua.is this normal and a match? or does this mean the barrels have been changed before.i bort it complete out of a bike that had been front ended,it was a long time ago and as i recall i think it was an unfaired version,but cant remember yr or anything.all i have is the engine complete,all be it needing a rebuild and a broken bit of barrel repaired,and carbs.going by the 1wt bottom end,and 1ua top,does anyone know what model parts i should be looking for? or is there a few things i.e. wiring loom,cdi,etc etc i should be looking for,but any model for other parts? dont know whether to do a rebuild back to original spec,or maybe make a yammagamma or a hybrid yet.as ive only got the motor,its going to be a very expensive and therefore sllllloooooooowwwwwwwwwwwwwwww build anyways,so plenty of time to make my mind up.anyways any help or advice would be greatlyu appreciated.
cheers

1WT with 1UA barrels is right m8 and is N2/F2 so ideally you would need N2/F2 wiring loom,cdi plus the other leccy bits to make it easier and plug straight in or if you could get your hands on a complete leccy set for a 31k you could use it,it would just mean the wiring on your stator plate would have different block connectors.

nice one.cheers dude.are they a good motor? the barrels have been.......shall we say tweeked.i wouldnt say tuned as such,more like transfers sharpened up,and smoothed in ex ports and inlet.ports in the barrel itself seem to be untouched.never seen a proper tuned barrel close up,so got no idea what a proper tuned (proffesionally) barrel looks like.as i say,i just bort the lump,so it isnt tested,and i would hate to spend a fortune buiilding a bike that ran like the proverbial sack of poop.tho thanks to spondon chris i now have a set of lc barrels that will finish off my spare lc engine.think ive been inhaling too much 2t,i seem to have gone 2stroke crazy.lol

don't know of any differences between the 31k and 1wt motor m8 so if u need another set of barrels you can fit 31k barrels if thats all u can get,not sure about the tuning question m8.
