nibbi Motorcycle Carburetor PE Carb with Air Filter (PE22FL) NB-AF2

I bought a Thumpstar that had only three hours on the bike. The float valve was stuck in the carburetor, so I had to find a carburetor for it. Everybody was raving about these carbs, so I gave it a shot. I have one on my Chinese 250, but I bought it with it already installed. I am so glad I bought this. The bike has so much more power than it did before, it practically throws me off the bike in second gear. The only thing that I would mention about it is the choke is not in the best spot for my bike. I really have to struggle to get to it. It’s a real pain to get to, even with smaller hands. I’m trying to think if I can design a contraption to get the choke up and down Here is the best thing about this carb: you have a huge adjustment ball which you can adjust on the fly. You don’t have to stick your screwdriver in and adjust a tiny screw. This is perfect when you have elevation changes and you need to adjust the flow. You really can’t do any better than these carbs. Also, beautiful packaging and with the proper filter. If you are on the fence, don’t be. They really just work. I’m glad I did it.

I would give this carb a 100/10 if I could, put it on my piranha 140 (previously had a mikuni) and it runs better than ever, I have to wind the idle screw out when cold starting and wind back in as it warms up but starts up every time first kick and absolutely rips. Could not be happier.

Super easy install on my stock engine. The included pack of jets made for easy adjustments.

We bought our grandson an SSR 110cc Pit Bike. For what it is, it's pretty great but the constant bogging, studdering, popping and rough idle was annoying and frustrating. After a lot of poking around the general consensus seem to point to the OE carburetor. I came across a lot of Nibbi carb swaps on various cc bikes and most reviews seem to be good, so I figured for the price I'd pick one up and give it a try. It fit the bike fine and it most definitely resolved the sluggish feel, bogging and hesitation. I set the air screw one full turn out and the idle screw 2 1/2 turns out as a starting point. The bike fired up on the second kick and idle fine from the start. Something it had never done, and usually died a couple to a few times until it warmed up. I messed with the OE carb a few times and nothing really seemed to help. The Nibbi was a vast improvement right from the start. The air screw ended up about 1 1/8 turn out and the idle screw ended up about 3 turns out after tuning. Idle to off idle were great and a bit of studdering and bogging at about 1/2 throttle. The needle clip was set to slot 4 from the factory, I ended moving the clip up to slot 3 and it smoothed out the midrange. I haven't had a chance to run WOT to check the main jetting, but so far I'm really pleased with the carb so far. The little bike feels a lot more peppy and throttle response is a lot more responsive now. I had to rig up a spacer for the throttle cable as it is a bit too long, as the cable seat on the Nibbi is a bit shorter than the OE carburetor. At some point I'll pull the cable to measure it and order a new one about and inch or so shorter, but for now it runs. The measured outlet on the OE carburetor was 18mm and the step up to a 22mm carb made a noticeable difference. A great upgrade for not a lot of money, that woke up that little engine and looks pretty good and seems well made.

Got it put it on my 110cc and has ran better then ever
