First of all, leave the chick man. I put my '02 F4i down after a 2nd gear wheelie at about 50 and my girl still cheers me on!
Secondly, congrats on the speed if you made it that far.....I took mine to 164mph (per speedo) and couldn't get her to go any faster, although my tach still had some room and my power commander wasn't running all the way rich and I only have the RS-3.
As far as parts. check out kneedraggers.com, they have a huge inventory and the people there know what they are doing.
