Whats the realistic lifespan of my stage one TC88? Or any of the TC's? I never pull full throttle much less ever rev to 4000rpm. I always get my service done as prescribed, and judging by the paperwork that came with my bike, prev. owner did the same. I just wondered cause I have a friend who had a '98 EG stage one and had 140k on the odometer when he sold it and it still ran beautifully, and he never had to do anything to the motor. I'm at 52k+ now BTW.
