WAT HAPPENS IF I STAY AT 12K FOR ALONG TIME? LIKE 1 HR OR MORE? BECAUSE SOMETIMES IN RIDING TO PLACES THAT ARE FAR AND I USUALLY CRUISE AT 80 90 MPH BUT THEN MY RPM IS BEING HELD UP AT 12K..DOES IT AFFECT MY BIKE? AND HOW?
If you keep up on the maintenance. Nothing will happen. Bike will get hot. Oil will break down faster. Use more gas. Bike will vibrate more and more. Change the stock gearing for an all around better ride.
