okay, I'm looking for help trying to locate whats not going right on my bike. here are the details.
PROBLEM: doesn't fire up, I kick and kick and it will fire a couple times, but won't take. and will occasionally backfire. it won't bump start, won't fire up with starting fluid. I don't have a lot of experience with dirtbike motors, but I get the concept.
What I've done: retimed it, put on a new timing chain, put on new piston rings, put new head gaskets on, put brand new valves shims in and adjusted them to factory, put a manual tensioner on it, removed the carb and cleaned it ALL. I don't get whats not right. I have spark, I have fuel, I have compression. is it normal to get fuel blow back through the back of the carb? not a lot but if I hold a paper over it and have my friend kick it you can see the paper get gas on it. which I find weird because, in order to have compression shouldn't my carb close all the way, there's always a slight gap on my gate in the carb, is that normal? I also read something about a stator key that if it's not sitting right you'll have spark, just not at the right time. or could it be my stator entirely? at this point I'm open to anything, I did not own it when it stopped, the guy said it ran, backfired and stopped. sounded like a timing issue or maybe shims, though I could fix it, he gave the bike to me for 900 bucks. said he didn't want to deal with it, so here I am.
