If you use regular carb cleaner make sure all plastic or synthetic parts are removed before soaking the parts. Remove all jets and plugs. Before reassembling blow every port, holes and parts with compressed air. It wouldn't hurt to replace all the fuel lines too. When everything is back together probably the most important thing you should do is a Link & Sync. These steps should be done exactly as stated in your manual. As far as boosting HP it is not as simple as some people think. Especially on a 2 cycle motor. With very few exceptions it is cheaper just to buy a bigger motor.
