That TT is bad ass and I love the remote starter idea, perfect for the track and in the garage if your just trying to get it fired up. 8 seasons is a commitment and it sounds like he's moving in the right direction if he's up in the B class.
The Wheels are 17", good catch! The forks are similar to the FZ6, these are 2000 R6. Drilling the rear wheel is a great idea, the lighter the rear wheel assembly the quicker the power can get to the ground.
I have another SR500 in the garage and I've thought about building a tracker...to run around town or at Lodi but I don't have the $$ to build two bikes right now. I do head out the a couple times each season so I'm sure I've seen the bike.
However I do have a fair stock pile of parts, heads, cylinders, etc if I ever decide to build a racer. I'll post more pictures as I get more done. Cheers!
