This bike has been rebuilt from the ground up. Seriously everything including of course the engine. Case has been split to allow for Timken bearing,bored to 95 inches,58mm throttle hog throttle body by s&s, stealth air cleaner s&s, air filter pre filter s&s 1" taller air filter s&s,new lifters, s&s 585 cam kit. Professionally built by Stiff Cycle in Nunica Mi . Got enough power now so I added a Baker six speed trans and handle grip warmers to keep hands warm@high speed. This is basically a new bike tires wheel bearings on up. Price might seem high, but only to those who don't know Bikes.
