I rode it all day and then one time it would'nt start. I put new plugs in and it did start again after trying for a while and ran fine. Stoped for a while and tried to start it again and it would'nt start. It's getting gas but it seems no spark because if I take out the spark plug and lay on the motor and crank it over it seems there is no spark. I did noticed a small amount of a black powder substance inside the spark plug boot. Could it be something as simple as not a good connection around the spark plug boot? I check the fuse's and they are OK. What else should I try? Thanks for looking KTM36
