Go Big or Go Home is the motto for this bad boy! How cool is it to be able to have a 1200 cc sled using the stock cylinders! We’ve done our homework on this one and it scares the competition! It takes a very intense porting job to do it. Not easy by any means. Every port is radically changed for optimum airflow and port timing and re nikasil plated. We modify the exhaust valves for clearance and you get a set of our forged 98mm pistons and a big bore billet head kit. We highly recommend the use of the 56mm throttle bodies for maximum horsepower. With our 1200 Fat Azz single pipe and 1200 y pipe this package makes 224hp and 157 lb/ft of torque. Add the 56mm throttle bodies, the 1200 cranks out 230hp and 160 lb/ft of torque!! F1000 owners will want to install bullseyes in the airbox, while M/CFR owners will wan to purchase our Big Flow Intake. Supreme Tool rave style exhaust valves are another excellent option for this package as they really help smooth out the mid range power. Comes with special large offset timing key. Power Commander 5 or Boondocker EFI Controller required. Exchange Cylinders & Exhaust Valves also Required.
Kit Includes: Exchange Big Bore Cylinders, Big Bore Billet Head Kit, Exchange Exhaust Valves, 2 Pistons with rings, circlips & wristpins, Timing Key.
