Can someone just try to explain why my bike would start INSTANTLY when I put it in 2nd gear, roll, and pop the clutch, and it doesn't start via kick start...If it were my valve clearances, lack of spark, carb problem, etc etc...then it shouldn't fire up instantly and run fine by the first method. I don't understand.
You are spinning the motor more than 3 or 4 revs when you bump start it, and you are spinning faster. That makes leaky valves less important to combustion. But I doubt that's the only issue............if it is the issue......
You should also:
- check the fuel screw is out only 1.5 - 2 turns
- check the hotstart plunger is well seated
- replace the gas. Old gas is a waste of time
- turn the idle up a bit
- clean out the pilot jet: OLD GAS WILL CLOG IT
