Big Bore Kits

JE/PR Big Bore Kits have been developed to dramatically increase the performance of your Yamaha Road Star and Yamaha Road Star Warrior. Oversize iron liners are installed in the stock cylinders (your cylinders are used as a core), precision bored and honed. Kit comes complete with gaskets. This is the same big bore kit we use on our AMA/Pro Star race bikes. We currently hold records for top speed and quickest et. We also have the number one plate on the bike ridden by Mark Underwood.
