Hey guys first post on here. I've had my bike for about 4 years and I re ringed it friday. Everything went good and we gotter back together and now it won't start and run. You can hit the throttle about halfway down and it'll will like sputter everytime the motor turns over but it never will catch and run. Can anyone help me with this problem. I'm in desperate need of it to run. We gotta get some cows up. Thanks in advance.

Sounds like the timing is maybe off or it doesn't have enough compression to fire up.
Does it have good spark?
Maybe the valves aren't sealing up.You could have a burnt exhasut valve.
