muffler question

[jake nielson]

Hello,I'm getting your normal 2 stroke exhaust oil all over my shoe and bike from the stock exhaust.So I ran a 3/4 inch pipe by about 3 feet from the stock exhaust tip to the back of the bike for a tail pipe,does anybody know if this will still let the motor breath enough? Thank's,Jake

If you are using the 16:1 break in mixture, go to 24:1.
3 feet of extension will definitely cause the engine to run hotter, and make less power.
