PWK Carburetor 21mm Performance Upgrade Racing Carburetor with Carb Jets Universal 50cc to 110cc 2T 4T Engine Dirt Bike Motocross Motorcycle Scooter ATV Quad (21mm)

Amazing. Worked Perfectly. May need jets adjusted after install.

If you have a Chinese 4 wheeler, this is the carb to add. You do have to make a couple adjustments, as it’s larger than the factory carb, but this one adds power as advertised.Added to a 250 Pentora. Bigger wheels made it feel sluggish. Adding this got it snappy again and boosted it back to popping wheelies with ease!! Definitely would recommend. *You do need some mechanical knowledge to install.

I bought this carb for a vintage yamaha Dt 400 cause the sizing was correct. Straight out of the box went directly on. And first kick started right up. Adjusted idle a bit and put about three hours of riding on it. Looks good and the bike runs good with it.

I received two of the same main jet sizes, bummer. I would recommend getting additional jets and needles for tuning.

The worst carb i have bought. The throttle cover screws was screwed all the way in causing an air leak. The carb worked once before it was leaking gas.Do not buy this

So far super! It came pretty much .. PLUG -n- PLAY !! Bike kicked over on 2nd kick only bad is throttle cable gets jammed in the carb its just to tall for most 110cc pit bikes but made it work and the performance i wasnt expecting much and i was very surprised it had plenty..

Good quality

It started leaking out of the float bowl seal brand new kinda disappointed in the quality of it meaning it is a big brand carburetor overall you do get the carb,needles,bigger/smaller jets.
