    You dont. Its normal for a 2 stroke. What are you mixing your gas at ? You can clean your chrome pipe up with a piece of steel wool just go easy and you wont harm the finish and it will remove the burnt on brown oil stains.

    What oil and what mix ratio are you using? Too much oil and you'll get excessive amounts of oil at the tailpipe, but as was said above, oil in the exhaust is normal for a 2 stroke engine. About the only exception is those weird guys, I'm one of them, that run the synthetics at very low oil to gas ratios. I'm at 100:1 and see very little oil residue from the exhaust. I'm not recommending you go that route but just food for thought. If you're still in the break in period don't go any higher in oil than 24:1 (disregard the instructions which might tell you 16:1) Better yet go to 32:1 and stay there.
    As for cleaning your chrome muffler, I'd use Brake Clean as opposed to steel wool. It will cut through the brown stuff and not damage or scuff the chrome.

    What he said; I went to opti 2 100:1 and will never go back to 2 cycle oil again. Great stuff.

    All of the above is very good advice.You might also want to try drilling a small weap hole on the bottom edge of your muffler where the exhaust tube exits.
    Also when you have your muffler cap off clean it and the inside of your muffler good with brake clean dry the inside of your muffler and squirt a thin line of RTV along the inside edge of the muffler about 1/8" in along the rim.This will help the cap seal to the muffler.Kip.
