Is there a gasket or should there be a gasket between the muffler and the manifold (bottom of engine where muffler connects via 10mm nuts)?

Thanks all for your input. Turns out I had a cracked intake manifold. Replaced and noise is gone.

Gasket for mufflers
by: Anonymous

On the Chinese Chua scooter, there are muffler gaskets (one) in between the muffler and motor. I went to Midas muffler, and they made me a gasket from one they had lying around (holes have to be made right). "Parts for Scooters" on the internet sells them too. I also used lock washers, and Locktite blue to help hold the bolts in place (the originals fell out).

Most of these are generic. Call John Sanchez at GS Motorworks (Eagle Parts) 1-888-400-3253 and tell him Jimmy from Scootdawg sent you. Maybe he has something. The Lance GS-R and numerous Eagle Tracers were fairly smilar.

Muffler Vibration bushing
by: Virtual4fun

Jim I appreciate it but none of them quite match.

If you look at #1 on the following link -->

it almost looks like that spacer/bushing but I will not spend 34.99 for 2 dollar bushing. Plus it appears to be a completely different style. Like I said I cannot find it anywhere on the internet.

Muffler Gasket
by: Ken

Thanks Jim. I do not know where my gasket went. I know it didn't drop to the ground when I took the muffler off. I had a problem several months back when the long 10mm came loose and I discovered one nut was totally missing and the other very loose. I am trying the copper ring method first in hopes of removing the high pitched sound I hear when riding. If that doesn't work then I will try the shaped gasket.

The weird thing about my muffler is that it attaches to the frame with a bolt that goes through a bushing (which was worn) comprised of steel-rubber-steel and threads into the frame. Local scooter man said he had never seen anything like that before. Basically it acts as a vibration guard/deadener.
I am using a roller weight as a substitute to hold it in place. I wish I could find the proper bushing though, as I am one to use correct replacement parts. Internet search has yielded nothing for my style muffler.

On my scooter there is a fibrous gasket in the head that's in a machined depression around the exhaust port. On some there is a copper ring that crushes as you tighten it. Others, a fibrous gasket between the pipe and head that the studs fit through. These can be found at

Battery Tender Junior in package

A battery tender like the Battery Tender Jr. can make all the difference in whether your scooter will start right up each spring, after being stored for months.

Just about every scooter owner needs to have a battery tender, sometimes called a trickle charger. Unless you are lucky enough to live in a climate where you can ride all year long, chances are your scooter will be put on ice, figuratively-speaking, for at least a couple months every winter.

One of the key steps in winterizing a scooter is to protect your battery from draining during its "rest" period. This can – and will – happen if you leave your battery sitting untended in your cold scooter over the winter, even if it's in a garage or shed.

Read our review or go right to to buy this highly recommended Battery Tender Jr NOW...

Wondering why your scooter question never got posted?

Chances are, there is a good reason. Did you...
