Engine running backwards?
« on: October 31, 2012, 05:31:44 am »
My friend went to look at a 1987 lt250r,Seemed cheap and he went to look at it (He knows less about than me and im constantly on here for advice lol) But he rang me and complained about serious kick back from the engine (Off the timming?Flywheel?) and when he took it for a test drive the key that's inside the fly wheel fell out (There is no stator cover on it) and he said.And bare with me as ive never heard of this before....When the flywheel key feel out the quad went through the gears backwards,Like he clicked it into first and it starting going in reverse ,Clicked 2nd and it starting going faster in reverse.Like the engine starting running backwards.Has any one ever heard of this before?

The key is what locates the flywheel into the proper location for proper timing. If the flywheel moved position on the crankshaft it will change the timing. If the timing is too far advanced it can run in reverse. A 2 stroke doesn't care wich way its turning as long as the piston is going up and down. I would check the groove in the crankshaft to make the keyway isn't boogered up.
