Buy about 6 motors, that should get you through a month or two.

Don't forget to buy stock in Amsoil or whatever oil you use, with how many times you blow the motor you will be going through a lot of oil !!!!

And don't forget a huge box of earplugs. Buy stock in an earplug company also.

Several ways to prep the bike depending on how much you want to spend, your riding level/expectations, etc-

For me- stock 03 XB9R with factory racing exhaust and ecm, XB12R airbox cover, belly pan, Nissan front brake pads and Michelin slicks. I retained the stock belt drive for now and have just recently installed a Penske rear shock and will have the forks reworked in the next week or so. I weigh 205lbs, so in order to obtain the correct sag numbers we had to max out the preload front and rear. This still left the front a bit soft for my liking, so I'm doing the suspension upgrades. I do think that if you weigh 140 to 160 the stock suspension will do well for awhile, but I highly recommend upgrading the front brake pads.

You can order the Buell XB belly pan and Nissan brake pads from Buell racing manager Henry Duga.  
 
email him at: henry.duga@buell.com
 
or
 
call 262-642-2986 and have him paged.

The bike will be competitive in class with the typical SV. However, you'll note a bit of a disadvantage in gearing selection with the belt drive, requiring you to modify your riding style for the specific track.

As for previous post regarding fragging motors- I have over 5000 miles on mine with several trackdays and races with absolutely no problems with oil loss through leakage or burning.

I am in the process of prepping a XB9r myself.  Since I work at a H-D dealership getting parts shouldnt be too much of a problem.............. ;)

Paul James is the man to answer your questions about the XB's. I am meeting him at MAM later today for this weedends races. He probably won't be on the board here till Tuesday. Mark B.

The XB12R is legal and pretty competitive in all the LW classes (SS, SB, GP) as well as GT Lights and Thunderbike.

Unless you invest some money into the motor, the XB9R is not nearly as competitive. Both bikes are legal for the same classes, so there is no advantage to buying the 9 over the 12, unless you plan to build the motor into a 1050 or something where the shorter stroke helps it rev quicker.

The stock suspension is really good. Top shelf fully adjustable Showa forks and shock with remote res. The chain drive swingarm conversion, as noted above, is an expensive option. Not sure it's worth it, especially for a newer rider.

Happy to answer any questions you have. You can PM me anytime.

Take it to Valley Racing in Beecher Il.

Or call them and ask, Brian Conley is a professional with building race bike motors, especially Harley motors.

Just give him a ring and fire a few questions at him.

That way you can get a direct answer instead of waiting for one on the internet
