i just recently stumbled upon this site and have found it very informative. there is however one issue i have with my quad that i did not see on here. i have an 84 yfm200 moto4. it has the automatic clutch. it has sat for sometime. the problem i am having is that when i got it started i was able to drivew it about 100 feet and then it quit driving. i have removed the clutch cover and the clutch does appear that it needs to be replaced. would a bad clutch keep this quad from driving?
