nibbiPWK26mm Carburetor with Carb Jets

Literally turn key. Didn’t have to tune or adjust it. Set up the throttle cable, mounted it and she’s good. I thought it was really cool that the lid of the box had a QR code to a manual/blueprint to the carb too.

Could not get carb to work properly on ttr125 motor with 150 big bore kit. Tried various main jet sizes, but engine would stumble when the power jet kicked in at high rpm. I also had problems with the engine stalling when the throttle was first cracked open. Tried changing pilot jets and needle position, but no luck. Seems like a good quality carb, but was impossible to jet correctly for my motor. Power jet may be to rich, but no replacement sizes are available. As far as the off idle stall, I could not get it to completely go away. In the end I bought a 30 dollar 26mm flat side carb almost identical to the nibbi carb, except for the main jets that were a different design. The 30 dollar carb worked like a charm and was easy to tune.*Update- I finally got the carb to work with the big bore ttr125! 102 main jet, 32 pilot, needle clip center position, mixture screw 3/4 of a turn our. Small window of error for the carb to work, but once dialed in excellent performance. I purchased a 2nd one and installed on a nsr50 2stroke with a 65cc big bore kit, easier to tune on the 2stroke engine. Jetting for the 65cc 2stroke - 135 main, 38 pilot, needle clip center position, mixture screw 3/4 of a turn out. If you have some patience and a bag jets it works great.

Installed it and changed the needle valve setting to closer to the middle then started my kids Apollo 125 and it’s awesome. Definitely more power idles and runs great(after some adjusting). We will see how time tells but for now it’s got good results. I order the adapter they recommended for the Apollo and fits good I used the Apollo throttle cable and it’s fine.

I drove an hour and a half last night after it was delivered at 9 pm and I brought it in to work to fix and the intake boot didn’t fit so now I just ordered that, I heard it works out of the box but apparently not

Great carb, be warned, it will be a tight squeeze for an apollo x18, but it works great and my bike actually has a good throttle response now.

I bought two of these to put on a predator 670. Runs SO much better! It has a lot of adjustments, but as long as you’re familiar with carb tuning, it’s super easy to dial in.

I love these carbs, they work as well as Keihin or Mikuni

First carb overflowed constantly, wasting half a gallon of fuel in an hour. Second carb was better but still overflowed some. Performance is good while running but not enough to justify pouring fuel on the ground.
