Hi all - I have been wondering about something since talking with my neighbor about some problems he is having with his 2015 HD Twin Cam motor .
In doing some internet research apparently there is a longevity issue with the cam chains , pinions & tensioners. Some feel that since the crank pin is pressed together it may be prone to the wheels getting out of true and causing the timing side pinion to run erratically.
Perhaps someone can explain how this can happen if the main bearings are sound and concentric. To my mind if the bearings are concentric how can the flywheels become non - concentric ..
I can understand the two wheels becoming untrue out of the crankcase but it seems unlikely to me that it would happen when assembled in the crankcase.
Puzzled …
