yamadoger Posted June 16, 2009 Share Posted June 16, 2009 when i got this bike i tore down the top end, only to find the piston in backwards and a very shoty base gasket . after looking closely and picking alot of old gasket material out of the oil journals and transfer ports i reassembled with new base gasket. and it still wont so much as fire. I also cycled through the timing and not a sputter. does anyone know about what these should have for compression. Link to comment Share on other sites More sharing options...
TylerP Posted June 18, 2009 Share Posted June 18, 2009 It should have 100 psi or better. Make sure the reeds are in good shape. Link to comment Share on other sites More sharing options...

Moderator Airhead Posted June 22, 2009 Moderator Share Posted June 22, 2009 Dont forget to open throttle wide when compression testing. Link to comment Share on other sites More sharing options...
