    Cylinder Core Exchange Options(see drop down menu):   

    • Option 1: Purchase Outright - No core cylinder or exhaust valves are required to be sent in - Raises kit price by $2000
    • Option 2: Exchange Parts, MUST send your cylinder and exhaust valves within 14 business days. As soon as you do, the $2000 charge will be refunded. Exchange parts not received in that amount of time will have no credit applied, and the customer will have to pay for return shipping. 
    • Option 3: Exchange Parts - Your order will be pulled on our shelf waiting for your exchange cylinder & exhaust valves to arrive. Once they arrive, we will normally ship the kit within a few business days. No core charge will be applied since we will have your cylinder prior to shipping the big bore cylinder. 

     

    Turn your fast sled into a rocket with this BMP Big Bore Kit! Our 900 kit for the 2010-1U F/M/CFR/Procross/Proclimb 800 HO models simply rocks on the trail, and climbing up the tallest mountains! Check out the dyno sheets to see for yourself, this is big horsepower, and huge torque! Test riders actually preferred this big bore sled as opposed to a pump gas turbo M8! This kit includes all work done to your cylinders(boring, extensive porting, & fresh nikasil plating), pistons(with rings, wristpins and circlips), exhaust valve spacers, and our billet head kit. You may choose to go for our stock head mod for that stealthy look for $200 less. However the billet head is recommended as it has more cooling capacity keeping you running temperatures cooler. Gaskets not included. BMP Fatt Azz pipe, BMP y-pipe, Stage 2 Clutch Kit and Power Commander are required. Boyesen Rage Cages and larger throttle bodies are recommended for optimum horsepower gains.

    ***Exchange cylinders & exhaust valves required*** If ordering online please carefully package cylinders & exhaust valves along with a copy of your invoice to: Bikeman Performance Plus 920 Pine Street Saint Croix Falls, WI 54024

    Kit Includes: Exchange Big Bore Cylinders, Exchange Exhaust Valves, 2 Pistons with rings, circlips & wristpins, Big Bore Billet Head Kit, Exhaust Valve Spacers, Timing Key.
