i have a small hole for my exahust on the end that can be removed and i was wondering if it would hurt to remove it. it gets red hot and i think it is double acting as a muffler... would it be ok to remove it?

Probly gonna need a pict of this one I got nothing. More information would be helpful. Almost sounds like restriction to be visibly red hot. Last night I had a Night Mare I dream-et I was a muffler in the morning I woke up exhausted......Sorry Snork sounded funny at the moment.

i think he wants to remove his muffler,and no dont remove it.
and yes it gets hot,its a muffler,and dont touch it or it will burn you.

Yes removing the muffler would cause a lean condition. Can leave a burn spot at the exhaust port. Not a good thing.

Your right if it were getting red visibly hot that CH would melt and go away!

The 2 stroke has no valves it breaths in two directions. Taking the muffler off will make it snort up un oiled air. You need an expansion pipe to prevent this problem. The term is called scavanging. With a tuned pipe it is the most effeciant it will snort back in unburnt exhaust that has oil in it. Making more power to boot. The stock mufflers are lacking a little for best performance... Hope this helps? This might shed some light http://motorbicycling.com/f30/2-stro...mber-3317.html

In the last section of tensioner #2 I changed my air filter it is actually a right guard deodorant cap with ten plies of shear energy . Youl get my point. The added distance and bigger opening I have the stock filter out done theres is no oily mess there. It matches the cfm of air moving now it is contained.

You may be running too lean if it truly gets red hot....I have painted a couple with regular (non heat) paint, and they don't get so hot as to burn the paint off.
