Considering the mods you already have and the cash you want to spend an air filter would be your next best upgrade.

I agree... but only needed if he went to 20" rear tires. And don't forget a rear skid for trail riding. ;)

yeah, a sprocket would probably help out too.

Air Filter will give you absolutely no additional performance. This has been proven on the dyno. You'd have to completely eliminate the airbox and then you would only gain 1hp using what is on the market right now with the exception of the FUELATV intake which will give you a 3hp gain.

Front sprocket is definitely the cheapest mod at this point if you need more low end. You will loose top end though.

the pro design intake works great,it eliminates the restrictive stock flash shield, and lets the motor breath, you will have to go with a power comander, or the pim to get the right mapping because it will run to lean if you have a pipe. You can get these things at KOQ racing.

If you're running SX it's usually tight stuff so you'll want the 13th front sprocket for accelleration out of the corners. I run a 13 in the front and 18" Holeshots for the rear.....trust me you'll be good with that for a cheap mod. You can put the 14 back on when you get more engine power and need the faster speed.
