Here's what my R has on it
fmf fatty pipe/silencer
custom dome
boysen reeds
39mm carb
full drag port
cool head
12/39 gearing
Last time I went to winchester I was running my 22x11x10 10 paddle extreme's and with my weight and gearing I can't hit 6th gear without it bogging, but 1st-5th screams, in a drag race i waste a raptor and z400 and a yfz and 450r at the start, but once I hit 5th and top it out the 450r and yfz smoke past me and keep pulling, and the raptor starts catching up after a while. Its a great bike but its hard to stay in the powerband once u get out of it, and you can't lug it up hills because of the drag port, thats why I am selling it and buying an 05' 450r which will only have a 12t front sprocket and filter/no airbox lid and I already know it will be all around faster than my R is.
