I need some help. The question is the motor (Year 2000Suzuki DT 140 TCXY E.F.I. (no carb). has about 250 hrs on it and I know that I should run some carbon cleaner through it. I did last year but then read on one of the forums that it was not a good idea for this motor.Something about ceramic heads on the pistons??? and that I had to disconnect a sensor. Any help and information would be greatly appreciated. Thanks
