If you want more power and grunt you can remove the air box snorkle to get more air. You can also get rid of the restrictive spark arreator assemble which will make give your bike a lot of low and mid end grunt. This also makes the little 200 sound like a freakin 450, it´s kind of cool sounding. I als suggesct usnin a high quality gasoline of 98 oyctane with a 20 percent by volume ethonal mix. Another suggeation is to get a free flowing filter like a UNI or twin air.
