Question on mo-ped

Hey everyone,

I have a quick question. On my mo-ped, on the end of the muffler is a silencer that is held in place with a nut. Its a cap that goes over the muffler that narrows it down to about the size of a pencil. I took it off the other day and it sounded like a pimped out Honda Civic. It was cool. Now my question is, is this bad for it? Will it like create a hot spot or anything on the piston with less back pressure?

I haven done it alot. I didnt know if it was bad. THats why im askin,

THanks guys,

Trac Man

Trac,

The real answer is, maybe.

If there is no perceptible change in performance then it is probably ok. You could do a plug chop with and withaout and know for sure.

You want to be careful on a 2-stroke which needs back pressure in order not to burn out the piston, but some moped exhausts are made way smaller than they should be to reduce top speed. The pencil-size hole is a good example. Doing something to the exhaust might not be that effective until you do something to the carburetor, if they've made that too small as well. The carburetor will be what limits air flow and the exhaust will mostly just be louder.

John,

From Trac's post:

From your post:

Sounds to me like this adds up. : )
