Default 660 Raptor improvements

I just got all of my parts, finally! Heres the list of upgrades-
GYT-R G Heavy Duty clutch kit
Wiseco Standard bore 11:1 High Compression Piston
HotCams Stage 1 cam kit
Yoshimura TRC Competition Carbon Fiber Full System

Over the next cuople of weeks I'll be putting it all together. What kind of gains in HP, low and top end torque do you think I'll be getting???

You'll feel a big difference if you had a stock exhaust before. Make sure you open up the intake too, get a good filter kit.

Get a pro-flo intake and cut up the box, If your below 3000ft, you'll be needing some 170-185 jets and 25 pilots. Have fun!

sounds like a good little "kit" have some fun, next mod you might want is a extended swing-arm. after all the extra power you will have the front end up in lots of gears.

I can't give you any numbers for the gains you get, But you sure will get that big seat of the pants number.
Congratulations and enjoy. =]

What is a good way to test and see if I have the correct jetting? Someone once told me about a spark plug test?
