Yeah, will be glad when its all back together (again . . .). Getting to know more than I ever thought I would about two strokes!

LOL for sure!

Then we can go for a ride at woodhill (when it opens again) I'll take a tow rope....

LOL - sounds like a plan. Hopefully we wont need it tho . . . after all this time, energy and money, I'm kinda hoping it might just run ok for a while!

Fucking two strokes.....

Two strokes are intresting thats for sure. just be easy while rebuilding it and you should be fine. make sure you put in plenty of oil again after the rebuild. and if using forged pistons rember to run in as per the instruction manuals

Doesn't really matter if it's 2 or 4 stroke as far as the gearbox is concerned,any engine with a vertical split case is the same - put them together,and then wonder where the hell all the bits left over go.First thing I do when the cases are together is check selection of all gears.

Funny thing was it was working to begin with. Then it found 1st by itself while I was pushing it, and when I took it for a test ride I managed to go 1st-2nd-3rd-2nd and it was when I went back down in to first that it locked up. Think I must have wound up with both 1st and 2nd for a bit there. Still, at least it didnt happen while I was in third! Might-a made a few bits go crunch then . . .

Second thing . First thing is check rotation of crankshaft !

Just been looking at it all, and 1st gear has dropped a tooth. Dont suppose anyone has a spare first gear for a 96-01 CR250?? Just need the gear off the countershaft, the one on the main shaft looks ok.

Bugger . . .

Speaking of which, what do you guys reckon, could I get away with a second hand one from a wreckers, or should I buy new? I'm a bit nervous about how much this might cost, and what other parts I may have to buy along with it. Will be phoning around the dealers getting prices tomorrow.

Hah! I was actualy going to put that,but it didn't seem to find it's way onto my post,I suppose I was thinking gearbox at the time.

I'd preferably go for a new 1st gear - 1st gets the biggest punishment on a dirt bike,slamming down without the clutch into those tight turns you overshot.It'd have to be a minta if second hand.

Oooh bugger...

you don't do things by halfs at all do you. piston in pieces, loosing teeth...

Oh yeah, I just seem to love making work for myself! Ah well, needed a good project anyways. Gonna phone around a few places today and get some prices.
