MX bike carb mod......

[Chipped tooth]

I was sniffing around on ebay and seen this.

It don't say where it came from or who did the work, anyone see this before?
I can't see how it would be any benefit......

After the mix goes through the crankcase, and transfer ports, good luck seeing any extra in the cyl.

Gimmick. Just as bad as the carb or throttle body spacers with some threads around the bore that are supposed to create a tornado down each individual runner.

2 smoke or 4 smoke? Not that it likely changes whether it "works" or not.

Maybe buy a bigger carb ?

Or offset bore that one bigger.
Done it both ways.

2 stroke. It's a PWK, which is a terrible choice for a 4 stroke. Plus it's been marked "KX500" on the bowl.
