Oh, and FMX, being ur talking about Dirt Bikes, I have a 1978 Suzuki DS 100 that I paid 30.00 for at a yard sale, it diddn't run but, it did after I changed the spark plug, the people who had it couldent figure out why it wouldn't run, now that it runs, it starts 1'st kick if it ran in the last approx 2 weeks or 3 kicks if it sat for a month, that's one good smooth running motor to. I also got 1 dirt bike motor question, my dad has a 1978 Suzuki DS 125 but, now when you hammer on it, it sometimes bogs way down and actully cuts out compleatly, it kinda sounds like it's loosing preassure or sorta flooding up but, it always starts right back up, got any ideas on what it could be? Also, when you start it cold it wont begin to want to start up until anywares from 6- 25 kicks and, it will idle cold but not hot.
