I've had a hard time definitively determining whether the Cruzinimage 600 kit, Wiseco 572 or the Yosh 562 produced the best power/torque increases over the stock with the 650 cam and a ported head. It seems like the higher compression of the Wiseco and Yosh kits make up for the smaller displacement increase and might even produce better performance. Anybody know for sure???
Love the bike, Scott.
