Arizona racer, Pat Bushell, used the summer racing sabbatical to send his 05 999R to Ducshop for an injection of horsepower. He was having a shifting problem, caused by a broken internal shift linkage, which had subsequently damaged his transmission. So while the engine was apart he decided to blue print it, to reduce the wear and prolong its life, and add some performance modifications.

Instead of just repairing the stock transmission Pat decided to replace it with a Corse close ratio transmission, shift drum and shift forks. The transmission increases the usability of the power ban and the forks and drum smooth out the actual shifting process. Pat already had the Dynojet quick shifter, which we reprogrammed.

High compression pistons were used to increase the horsepower and since the bike was used for racing we replaced the cast Ti rods with forged Pankl rods. An inspection of the heads showed much improvement could be made with a competition valve and porting job.

To open up the power we replace the 57mm Termignoni system with a Corse 62mm resulting in a sub frame and tail section change. Fabrication work was also needed to the rear brake lever location to accommodate the larger pipe. We then re-mapped his PCIII USB making individual cylinder maps for VP race fuel.

Pat already had a slipper clutch but we improved it by venting the clutch housing to help it run cooler.

And to keep oil out of the airbox we added a Corse reed valve.

Lastly Mark rebuilt his Ohlins shock and added a Brembo GP brake pump, making the entire bike race ready for some time to come.
