freenote Posted June 11, 2008 Share Posted June 11, 2008 I've just bought a 2001 Yz 250 and it runs like a dream - when i can start it!!! I've heard with the four strokes you need to have the piston at top dead centre, is it the same with the two strokes? if so, how do i tell when it's at top dead centre? Please help, it's driving me crazy!!! Link to comment Share on other sites More sharing options...
