Please do not ride with your baffle off...we have enough groups here in Tucson that are trying to ban Motorized bicycle again.

Before Oct. 06..motorized Bicycle were illegal in the Sate of Arizona. A lot of people worked really hard and spent lots of money to pass HB 2794 to give YOU the right to ride your MB. Ridding around without your baffle is not helping the cause.

I grew up in a school of motorcycling where people were told not to pull the baffles when they rode. It wasn't as much to do with the noise as it was with keeping oil on the cylinder walls. That little bit of back pressure was believed
to actually aid the lubrication of the engine and keep it from possibly incurring a cylinder wall/piston seizure. Todays better 2 cycle motor oils do a good job of
lubricating with the BIA/TCW standard, but who wants to overhaul the top end
just to have some noise.....which will be the principle gain of pulling he baffle.

And these Chinese cylinders don't have a steel sleeve in them like the Russian ones did. They have a hard chrome coating I understand that helps enable it to hold oil better as hard chrome is porus....but may not be so forgiving of a seizure. I've wondered if that's why some of the mufflers that come with them
were made such that they couldn't be taken apart.

Now...why even bother removing the baffle? Do you just WANT to annoy people with loud exhaust?

I agree with eDJ. These engines require backpressure to last. If you do pull the baffle, I dont think you will have to worry about it making loud noise for very long........

Some mufflers have an end on them that comes off, and the end has a baffle attached to it.....

The baffle is a piece of sheet metal or some have a tube inside the muffle. The baffle serves to deaden or soften the exhaust pulse sound.

Removing or modifying the baffle increases sound and the sound becomes "sharper'' or more crackly.

If you remove the baffle, be sure to run a plug check and listen to the engine. Make any adjustments to your mixture that you need to. The engine will usually (always) run leaner with less baffle.
