ok, conditions were the sandhills, and it was round 98 outside. didn't ride hard, and not for very long. just round 10 to 15 minutes a run. didn't want to push it, since i just redid the carbs. but i did let the motor get cold, and went riding, and the resevoir did fill up and fluid did come out the hose again. added more fluid to the radiator.
i don't know where the gear is that you are talking about to check it, so if you could let me know, i will check it. and how do you know if the cap is bad. just by replacing it or what? thanks for the replies.
