you can get a bigger front sprocket but it will take away from ur low end power.
u could also put a stg2 cam in.

There are a lot of things. Aftermarket exhaust, airbox mod with hi-flow filter, hotcams, drz gasket...just to name a few.

Are you looking for torque or top speed?

im lookin for top speed but not loose too much bottom end

i thought bout a 38 back sprocket and a 13 front sprocket

that combination right there does nothing for you! if you drop a tooth in the front for torque then drop 2 teeth in the rear for speed you have offset the front sprocket. so your basically right back to stock. i pasted a gearing calculator in here somewhere for the Z's and KFX's because jonboy was messing with the gearing. check around and youll probably find it. dude its generally high speed or torque. best of both worlds is right in the middle and thats where you are right now. unless you want to big bore!
