Guys,

We're having duscussion hear about reasonality of lightening\balancing\knife edging crank. I will appreciate any dyno result for race engine with\without knife edged crank. I would like to check how changed power and torque moment after such modyfications. Or maybe personal opion about this. So, any information will be helpfull.

Thank you.

Had one done years ago on RVF, was a bag of shite, great on tick over but when reved it just vibratted so bad it actually blew up on its first lap!! And crank was done by a firm that do Formula ford and F3000 engines so no back street job.
RLR does not do it, even to Mcguiness TT bike, think that says it all

Thank you for response.
