  • Carb saved my Quadzilla LT500
Color: Grey Size: PWK 40MM
Worked right out of the box with my LT500R build. I bought it to replaced a Keihin 39mm with worn out emulsion tube and jet needle. I was dealing with an annoying hesitation at 1/8-1/4 throttle transition creating a very rich condition (carb would not adjust no matter what I did). I decided to roll the dice and bought this carb. It came with 175/50 jets installed, extra jets and extra jet needle. Worked great. I just had to adjust both the idle screw and air screw a little. This $35 carb save my quadzilla and works just as good as the OEM Keihin that costs $350-400. The emulsion tube is removable which I think is a great improvement over OEM Keihin. Parts (slide, etc) however are not compatible with OEM Keihin. Chinese carbs are a hit and miss thing but I would give 5 stars to this one after hearing/watching good reviews on Youtube. ... show more

  • Worked as well as Brand names

  • No where near enough jetting for a large displacement two stroke.
Color: Grey Size: PWK 38MM
Had to change the needle and jets to flow about 40% more fuel for a yz300. Main upped to 182 and pilot to 55. Needle is small changed to nz03. Now it's very crisp and responsive.

  • Just as good as a genuine Keihin!
Color: Grey Size: PWK 38MM
Just as good as a genuine $300+ Keihin 38mm Air Striker! Be aware you will have to buy the correct jets separately for an 'astronomical' $10. My '00 CR250R requires a 55 slow & 178 main for peak performance and after I installed them it made my CR scary. Before the powerband was narrow and bogged now it hits low and has no peak...it just keep climbing. The freakin motor would blow before I reach the limit. Also I removed the flow bowl drain & filled it w/ superglue. Now it doesn't leak drop no matter how far I lean it over. Before I couldn't get much over 45. Now I bet I could get almost 80mph out of it. ... show more

  • It's the best carburator I've ever bought
Color: Grey Size: PWK 38MM
It came with different size jets so I was able to tune it exact for my rm250. My motor really came alive with this carburator

  • Did not work at all with my kx125
Color: Grey Size: PWK 38MM
I installed this on my kx125 and anything past a quarter throttle it just bogs out and shuts off, not sure if the main jets too rich or what but it does not work as intended
