2: Hotcams! a set should add 5+ hp to the mid to red line over stock cams. I got my set off ebay for $US300. I haven't got them yet, they are currently somewhere in between USA and Australia. The YZ exhaust cam just moves power higher in the rev range.
3: High comp piston. More compression means more power through out the whole rev range. Stock compression is 12.5:1 for your model, JE make a 13:1 and 13.5:1, Wiseco make a 13.5:1 also. I got a 12.8:1 (my stock comp. is 12.3:1 for '05) because of fuel quality concerns. If I had 98 oct I would have went 13.5:1. As above too, mine is in transit.
4: Bigbore kit. Heaps more power bottom to top, but power falls flat on it's face after peak. I couldn't afford a bigbore kit, I got the piston and cams instead. Ialready got a Procircuit Ti GP lowboy system which adds a crap load of power to low - mid, as well as some top. I felt my bike is a bit flat on top so I went the cams direction.
I believe the combo of pipe, bigbore kit and hotcams would be absolute killer if you had the money.
Definately start with a pipe if you don't already have one as there is awesome gains to be had right there to start with.

Sounds like a real beast!
A 470 kit is going in, and a few other tuning parts. It needed a rebuild anyways, it has 3000 Baja and street miles on it. Some carb work will be done also. I still have the hotcams if I need them. I'll let you know how it turns out. Suspension is out to Enzo also. We carry extra weight so I need it firmer.
