sorry, i meant gear case, i thought there may have been a way to check the level. this bike has sat for many years and not done many miles. i just replaced the exhaust coupling this evening and discovered that the exhaust was loose at the cylinder. after the repairs the bike seems much snappier but the petcock is giving me fits (i have one on order). i have played with two strokes for years but mostly all in snowmobiles. this is my first dirt bike ever and there is a small learning curve it seems. but having a blast both learning and riding. thanks for all the help..... kevin
