    Speedwerx Ported GP1200R top end

    I want to hang on to this set-up but it makes more sense to sell to offset some of the cost of building my 1456 motor so my Speedwerx ported 1200 cylinders with oem power valves & 145psi head are for sale (no pistons). Cylinders are standard GPR 80mm bore and the head is pump gas safe. Cylinders have 65 total hours of use and 40 since the speedwerx porting. Power valves have 10 hrs. Head bolts & girdle kit for the cylinders are included. This is a very nice set-up to say the least and has to be one of the strongest 1200s around! My gpr with these cylinders and speedwerx triple pipes had run 85.1 @ 7900!!

    $900 plus shipping & paypal fees

    New price - $800 plus shipping/paypal

    I would also sell the gas valves that have already been matched to the Speedwerx cylinders in place of the pvs for $1,200.
