yamaha superjet blaster fx1 850 Superbore bigbore Kit [SBkit] Do It Yourself kit, to convert your yamaha 62t 701 or yamaha 760 cylinder into a yamaha 850 monster. Includes a special ada head anodized in red, 2 proprietary custom superbore big bore sleeves, 2 custom domes, 1 girlde kit. You will need to procure cr500 pistons from wiseco/pro-x directly (we can source this in addition) and a base plate (available in addition). This is a kit for people with building skills, it's NOT a press on job. There is a lot of grinding and modifications needed, but again yamaha superjet or blaster 850cc... Nothing better than displacement ;-)
This kit was developped in collaboration with a 2 builders and is build with freeride/freestyle in mind, that are incorporated into the design of the sleeves. We will offer those kit in a already built form in the next few months. Kawaparts4u/Howi Jetsport is the exclusive reseller of those sleeves and kit.
