Re: She Just Ain't Climbing Like She Used To - Standard China Girl 66cc
BRO,That's a GREAT road for a motorized ride. I wish I had one like that around here.
As far as your pipe goes, That's how I run all my bikes. If you've ever cut one apart you'll see that, way up near where the pipe is welded together, there's also another "Honeycomb" baffle. (pic. 1) This also gets plugged a little, which in this case is a good thing. It plugs just enough to give the engine the little back pressure it needs. I'm a firm believer in combustion chambers, but I'm poor folk and those things are pricey for good ones. With a few years of experimentation I've found that a chopped stock exhaust and sometimes a little carb tuning, (jetting,) works great with these little girls from China. But your bike sounds great as it is. A combustion chamber is usually also a little loud. So if the cops in your area don't mind the noise, and YOU don't mind the noise, I'd leave it as is. Just keep a close eye on your plug to make sure it burning right. Black oiley plug, smaller jet. White ashey plug, bigger jet. Tan or brown plug, Just right. (And jets are a lot less expensive than expansion chambers.) The pipe on my bike now is an old beat up one that still works too good to NOT use.
