you're just gonna kill yourself, take it easy.
Get Thatkid to build you an R6 header, put an aftermarket (FMF, Yoshimura, etc.) pipe on it and it should make enough of a difference for what you want to do. Follow our write-up under his section.
I couldn't do wheelies at all with the stock 530 chain 15-45 sprocket set-up. I could do small wheelies with the 520 chain and 14-47 sprockets. With the R6 header I can do wheelies all day. Honestly though, "power wheelies" are really not going to be normal for most FZR's... at least for our heavy steel frame 600's.
Notice that FasterThanUr is running 14-49, R6 header and custom ram air, also i'm pretty sure he's running a lightweight 400 aluminum frame.
