just bought a 04 yz 125 blown up replaced piston it has an 05 motor in it... anyway starts fine now but wont hit the.powerband at all starts and idles fine just has.no power was thinking its got a bad stator does anyone have the readings its supposed to give out?? the bike has given me alot of shit so far the piston wasnt right at first was standard size but too tall for the head it has a yrrd head so kept hitting it for some reason anyway I fixed that by putting a double base gasket down dont no if that would be a cause of no powerband??? im pretty sure its the stator though if anyone can help me with resistance or voltage readings??
