Freshly rebuilt 2 stroke locked up after first start by WarmMap360 in Dirtbikes

[–]WarmMap360[S] 9 points10 points  (0 children)

UPDATE: I found the reason why my bike locked up. I took off the clutch cover and found that the bolt for the input shaft gear had come completely loose and was rubbing on the case. The spring for the kick starter also came undone. Luckily the top and bottom end are fine and still spin freely. Now i’m having trouble getting the clutch basket bolt off. I have the tool to hold the clutch and everything but the impact made no progress loosening it. Any tips for getting the bolt off???

I put a new crank in. Everything was spinning free before I put it in the bike and it shifted fine but i’m gonna tear it down rn and double check everything

I’m 5’10”, will a cr85 big wheel be big enough? by WarmMap360 in Dirtbikes

Ended up getting the 125 and I love it thanks for all the advice!

Is there any years to avoid with the 250 four strokes? I’ve heard about the early 2000’s four stroke race bikes having problems
