Hey everybody. i have already done searches and couldnt find my answer
i just got my bike fixed. its a yz85 with big bore and other things. i got a new crankshaft asembly and new top end. now after breaking it in, when i am going really fast in 6th gear and let off the gas it suddenly kills the engine and locks up the rear wheel. i have to stop completely and put it in neutral to kickstart the engine. and it does this occasionaly but only when i give it alot of gas in 5th or 6th gear and let off the gas quickly. can anyone tell me what is causing this. oh yea and i already pulled off the cylinder head and checked the piston for seizure or damage and there isnt any.
