I am building a 1990 Kx 250 am have got a wierd ? I got it all back together except chain on the bike. I tried starting the bike without the chain on it. The gear shifter needs replaced as it will not tighten down enough. The ? i have is if the engine is in gear will it cause the kickstarter to slip some. I can kick it once and then it like slips several times before it catches. I took the engine back off and looked at everything qand cant find any gears or springs nmot working. I know on my KZ 1000 if the bike is in gear and u pull the clutch it slips totally but im not sure about this Kx250, just wanted to ask before i put the engine back together.
