Howdy,
So here is my story.
This quad has been a great machine thus far. it started to have the usual hard to start issues so I ordered a new cam, and rockers off line. parts came and I tore it down and replaced both rockers and cam, reset timing and it fired right up. Still had a hesitation on the initial rollover, I thought maybe my starter was going tu so I replaced it. No change. I havent done anything since cause of regular life things until tonight when it started snowing. Went out to shop fired it up and made it about 500 yards and it died. Hit the starter and it just rolled over like it had no compression. got off of it cussed at it a minute and walla it had compression again, drove it about 80 feet and it died again. Drug it back to the shop and started messing with it. pulled valve cover off and everything seems to be moving freely up and down like it should. got it to refire and it ran for a few minutes then the no compression thing again. I can put my hand over the exhaust and it will suck and blow through the exhaust pipe. any ideas?
Thanks in advance.
