Quick run down, i got the bike from a guy on craigslist. He said the top of the motor was all new and that he replaced all the stuff himself because it dropped a valve drestroying the piston. It took him awhile to get it started when i was looking at it but he said it was out of gas so we went to the gas station and after about 3 strong kicks it started and idled and i drove it for a very short ride around the gas station before i took it home and then spent another hour trying to start it again with out any luck. he said he had about 5 hours on the new build. He also said that the exhaust cam may be off a tooth. My friend owns a small engine repair shop so i dropped it off for his mechanic to look at it he tore it apart and said the piston was in backwards and the rings were upside down. he put it back together and still couldnt get it to run. He recommend i get a new timming chain and cams because he thinks either the chain is stretched or the cams may have slipped on the gears. ALSO i found that the cams,chain, and all the valves but one are not new like the guy said that i got it from. Heres where i am now, i took the bike back from the shop to look it over myself and i dont think the chain or the cams are bad and that it was more like a 400$ guess. I adjusted the valves and found that one exhaust valve was comepletely missing a shim, so now all the valves are adjusted correctly i also threw in a new spark plug, a new air filter, and i have a new chain but didnt install it unless i need to and dont think i need to just yet. its got spark(idk if its at the right time or not) and the carb is spraying fuel and all the jets and such are free of debreis. I also did a cylinder leakage test and it seems air tight. Im not sure if i have the timming set right but i got the "I" lined up and have both cams with there dots horizontal with the case. I counted 14 pins between the top two marks on the cams. If i set it to 13 pins then one cam will be what looks like a tooth off from the mark on the head. Now im not sure how tough its suppose to be to kick over but i run into a very hard tough spot when trying to kick it over but figure its as the decomp cam is slowly letting pressure out then it gives way and i can power through it. ALso im wondering if me having the vc cover off the engine would keep it from running i wouldnt think so but idk. I put the intake back on and the exhaust is on thinking they might have to be to get it to work. just to be sure but ti start it cold its turn on gas open choke turn throttle 1 to 3 times and kick like hell ANy help would be great! thanks! Erik ill also try to get pics up of how i got it timmed.
