Is a muffler modification possible for increase in power on a Shanghai Shenke scooter?

by Tim

I have a Shanghai Shenke 50cc moped/scooter. I'm wondering if there is any modifications I can do to the muffler (to improve airflow) without spending any money... Basically is there something I can remove from the muffler to increase power.

 Is it a 2 stroke or a 4 stroke NEW
by: Anonymous

If it is a 2 stroke bypassing the restrictions might help but drilling hols or removing baffles from the exhaust will kill your performance, If it is a 4 stroke pull off the hole system(that is not legal and will probably burn your valves but it will sound cool and get a little more power for a wile).

 look for restrictions
by: dadob

It's pretty easy to take the muffler off. Don't loose seal at the cylinder head. Some 50cc not 150 cc scooters have restrictors, but it's becoming less and less. You will have a noisier scooter if you open up your muffler by drilling holes or removing restrictors.

Restrictors are becoming rare but... sometimes a thin washer welded inside the input of the muffler, or a narrowing of the tubing, which requires hack sawing and probably some good welding or serious screw tightened patching to overcome, are available.

Look up on web about variator restrictors too. Not hard to do, but also less common in newer scooters. You're not going to get more than 40 mph out of a 50cc without greatly reducing the life of the engine.

It's much cheaper and easier to sell and get a 150cc which can get two riders to 40 or 45 pretty quickly. Occasionally 50 with the wind at your back.

 Punch Holes in the Exhaust?
by: Anonymous

Punch holes in the exhaust. This will make it bodied and better airflow and more power. Also if you can remove the insulation.

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 Amazon.com to buy this highly recommended Battery Tender Jr NOW...
