I have a 04 Raptor 660. I haven't done much. I have a Yoshimura Slip-on pipe K&N air fliter (Dyno Jetted) and a 12 tooth sprocket. I'm looking to make it faster on the sand without spending alot of money. Any information would help.

do you mean 12 tooth sprocket... usually people drop one tooth to a 12? this helps, but im betting you meant to say 12...

an aftermarket cdi that increases your redline a grand helps a little, but not too much...

piston, cam, and porting seems to be the next step for you
