Ok. Here goes nothing. I have a Franken bike. It's half 99 half 01. Not really a big deal. So the lady I got the bikes from said it jumped time and won't start. One bike is complete and assembled the other is in pieces but there. I have had these for two years. I immediately did a tear down and rebuild. I went over everything. Well fast forward to now. I found that she only had 4 head bolts in it . That is why it jumped and also why she said the timing chain had to be real tight. I can get it timed well enough to start and idle rough. I've replaced bout everything. Compmetely new head and all head components. Upper cam gear, chain,cam,the whole thing. It won't line up matter what I do. The timing marks are just a wee bit off. It won't rev just backfires and dies. I've had the bikes for two years and can't get it. Great spark-built a bare bones harness myself. Great fuel-rebuilt the mikuni and bought an aftermarket, same outcome. I ha e half of mind to sell the two and but something else. PlEase help. The wife might kill me if I work on it anymore. Idk
