...riding.Turns over but wont catch.Why? Bought this bike from a friend and it had been sitting for a while. Only has 10k on it and was working fine for him.He upgraded to another bike and held this one for me till I paid him off, about 9 months. Could sitting have done this? Spins fine, spark from plugs when I take off cap and turn motor, has gas. I'm lost in the sauce, can somebody help?
