heres my problem. i have an 89 kx125( i know enough said right there but theres more. lol) the bike will start on the first kick for the first time it is started that day. after it had run and warmed up it will not kick start, i have to push start it, and even then it doesnt want to start all of the time. I did some plug tests and it was carbonized, and very oilly and gassy. what is up with this stuff? needs jets or what im clueless. thanx in advance and sorry about the length
