Unless that carb has a mixture screw on it in addtion to the idle speed screw, I'd pass. You can get a K&N or other filter for a lot less than 50 dollars!

Don't waste money on a boost bottle, they are proven to be a scam, or imagined performance booster at best.

You can; optimize your mixture, match your ports to the intake and exhaust, lap your head, remove one of the base gaskets if your bicycle motor came with two installed, cut/drill, or remove your baffle, open up your air filter cover, and balance your wheels.

Also, after break-in, your bike will be smoother and faster.
