Hello, I think I might have got hosed on this dirtbike I bought. When I got it was a bit hard to start but the guy said I just needed to learn the techniqe of starting a 4 stroke. I went with that and I have been riding it for about a month now. It has been come very very hard to start now, so I looked into and cracked it open to check the valves spaceing. The intakes had almost zero spacing. I went to my local kawi shop and traded some shims to get it back into spec. I was reading threw the cyclepida manule putting everything back toghter when I realized the exhaust cam didnt have the automatic compression release like the manule said it was suppose to. I was thinking maybe the guy put some aftermarket cams in there or somthing. I did just like the book said getting all the timing lined up. Not when I turn the motor over when it gets the the lobes on the exhaust cam pushing the valves down it just stops. I tried retiming 4 times. Does anyone have a clue whats going on with this?
