It is not necessary that performance filter is better, maybe that filter is too dens and your pocket doesn't get enough air. What to do? You can make your own custom air filter, from some cushy material like steam filter from an dip fryer. (I did that and it is working perfect) That is not only thing you can do to make your pocket stronger. Butt it is the easier. Of course after that you must set up your carburetor all over again. Air filter must have hole big enough to ensure enough air for explosion. How will you know that your filter is good. Top speed! Your pocket must work perfectly, with constant acceleration until it reaches full speed. And at full speed he must work without any deceleration. Try couple of runs without filter, and then try to fulfill same with your filter. If you made it, filter is good.





First steps

If you don't have enough experience about 2 stroke engines then you should give up at the beginning.
