The race bike proved to be a solid combination last season so the winter upgrades were to improve rideabity without adversely affecting reliability.
The first upgrade required the expertise of ace Buell tech, Reese, who installed the Buell high performance oil pump drive gear which was developed from the Buell racing program to provide additional longevity. After it was back together Reese tweaked the timing and dialed it in on the dyno. Right now it is registering 91hp at the tire which should be more than enough to be competitive in the Amateur Lightweight SuperSport class this summer as long as I can continue to improve my riding skills.
The second upgrade was to replace the 3.5lb transmission pulley with a new aluminum piece from Evolution Industries, weighing in at 15oz, thanks, Gary!! Any weight that can be removed from the rotating mass will equate to a quicker launch out of the corners, plus it's just a bolt-on!
The third upgrade is the intallation of a 1/5th turn racing throttle from Double Z Racing. I hope this will help me maximize all the XB's power by getting to wide open throttle easier and quicker! Thanks, Lohman!!
The fourth upgrade is in the works right now. I'm replacing the stock XB fairing with an 1125R piece for improved aerodynamics and an updated look. The 1125R fairing should have a noticeable "aero" improvement at tracks with long straight-aways like Road America. The big task now is to develop a pair of fiberglass headlight plugs, paint the yellow number plate, add my numbers and get it installed. When the parts came in Troy and I had to do a test fit a the dealership, looks good!! #143 is Troy Walbaum's XB12R race bike.
Well, I'd better get to work!!
