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,
