my trusty old puch nostalgia.
I know it has the bushing crank just wondering if I'm pushing my luck...has a 14 bing, techno pipe and airsal 70 kit.
I while back my wife and her friends went bar hopping and the friend riding the puch was struggling on hills...I swapped out the gearing from a 17 front to a 15 front and it is lots peppier on hills but when i wind it out I fear the bushing is taking a beating.
I have a digital tach and when i was riding around the other day i was surprised at how high the rpms got (12-13K).
I know that's bad but was wondering what is considered a normal rpm for a kitted puch. It doesn't get pushed much (except by me)!
I've heard 8500 rpm is about your limit for bushing cranks before they start to go bye bye...
