Exhaust for Yamaha PW80 clone?

[Tkopper]

OK I got this 100cc Jianshe Flywing 11 years ago for my 13th birthday. After years of torture she is still hanging on but just barely. I was thinking of throwing a Lifan 125cc in it. My only question is what pipe will fit this frame and perform well with the Lifan? The frame is a clone of the Yamaha PW-80 with the difference being that it has a Honda 50cc cloned Engine bored to 100cc. Many years ago we replaced the stock pipe and carb with a 26mm Mikuni and straight pipe. Would like a standard pipe again as the straight pipe is beyond loud. Anyone got any ideas?

Thanks, Tom.

Welcome to Minirider's,

First up drop in here and Introduce Yourself


I'm pretty sure it will take most CRF50 straight pipe exhaust's, as they originally came out with one like this

You might need to give it a little bend to get it to sit right, but seeing as the pipe's are pretty thin it's usually an easy job
I would be buying a new air filter too for it while you are getting the exhaust, i'm pretty sure they use a 38mm filter

Cheer's, Craig

Oh nice! Yea I will have a uni on the new motor.

This bike just survived last weekend running without a filter! For some reason it would barely run with the filter on. Been sitting for a couple years so who knows.

Thanks!
