First thing I did was get pipes(cpis=540),Shave my head(65),sprockets(16t=10),timing plate(35),and I got the tors removal kit which was like i think 45-50.I ride trails with 4pokes and 4x4s and Im happy with It.Pretty suprised how good it does with CPIS and 16t sprocket.I also like to do a little racing to.This was all done at the same time I spent like 650$.I did it all my self except for the head part.Also got my bike tuned awsome for free.
For like 800-900 you can get everything I got plus porting.I regret not getting it ported that day.Im going to get an agressive trail port.
