I need help... It all started a bout a month ago when one of my shift forks decided to go. I tore it all apart and replaced everything that need to be fixed, buttoned it back up and put it back into my bike and now i can't get it to start. I have spark, i have fuel, the bike has compression and i'm pretty sure it is timed. Timing it has been a pita i started by trying to time it through the right side off the gear, Tried starting it and all it would sound like it wassn't timed right. so i got on here and learned about timing it off the flywheel. when I do that the mark on the gear is about 90 degrees off from the flywheel mark for tdc. i've set the timing off the flywheel and still nothing. if i give it a lot of gas it will backfire every once in a while other than that nothing. My questions are: 1. Why is the marks not lining up from the flywheel to the gear on the other side? 2. Why wont it start?
