VM22 26mm Carburetor for Intake Pipe Pit Dirt Bike 110cc 125cc 140cc Lifan YX Zongshen Pit Dirt Bike -VM22 26mm Carburetor

I installed this carburetor on a Pitster Pro FSE110R. Initial impression The kit came complete with all the parts and accessories for installation. The overall quality of the parts is very good. Some elbow grease (see details below) will make a smooth install and operation. Carburetor Carb itself is very high quality. I removed the throttle slide cap and de-burred the top edge with sandpaper so it does not tear into the rubber gasket in the cap. I checked the float height and it was set properly from the factory. The choke shaft seemed dry with coarse metal-to-metal contact. I sprayed very little at the choke shaft to make it operate smoothly. Manifold The manifold opening measures 25.5mm on both ends. The manifold is angled, just like the OEM manifold on the FSE110R. This is to offset the carb away from the frame. The new manifold is slightly taller because of the taller VM22. Before the install, I took a sandpaper to smooth out the sharp inside edges around the intake runner. I reused the OEM bolts to attach the manifold onto the engine, don't forget to install the new gasket here. Carburetor Spacer / Thermal Barrier Again a sandpaper comes into play to remove the burr. Don't need to go crazy because the o-ring makes the actual seal. Mounting Carburetor Make sure to install the carburetor with the spacer (and o-ring) between it and the manifold. The provided (M6) bolts are the proper length. Since the OEM carb has the nut integrated into the carb, I had to sourced two M6 lock nuts with nylon inserts. I like the idea of using this type of lock nuts because, one, the nylon insert prevents the nut from backing out due to vibration , two, I do not have to risk over-tightening the bolts and cracking the plastic thermal spacer. Remember, there are o-rings on the spacer and the carb. You only need to fasten the nuts enough to create effective seal. Don't crank it down too far. Additional tips: 1. In my case, the bolts go in from the manifold side, through the spacer, the carburetor, and the locking nuts. 2. For the bolt and nut on the choke-side, you may have to temporarily lift the choke lever to get the nut in place, while threading the bolt through. Hoses Connect the smaller ID hose at the bottom of the bowl for fuel / overflow drain. Cut the larger ID hose in length for fuel feed. Use the remaining or cut it in length for the overflow / vent. Air Filter The provided air filter is good quality with two-layers of foams that are different density. Make sure to oil the inner foam properly if you ride in dirt / dusty places (i.e., offroad). When in doubt, it's always a good practice to oil your foam filter. Bonus / Optional 1. I installed a pre-filter / sock for easier and less frequent foam cleaning down the road. 2. I also installed an extended fuel screw for easier turning. [UPDATE 11/16/2020 - Carb Tuning / Fuel Screw] I took my daughter out and did some riding and carb tuning. Long story short, with the oiled pot filter and OEM (straight-through) exhaust on the FSE110, the fuel screw is 1.25 turns out. My daughter is very happy with the new carb, she says the bike runs smoother and stronger. We also noticed that the throttle travel is longer than the OEM VM19. It is actually better as VM19 has shorter travel and is harder to modulate. [UPDATE 3/15/2021 - Reliability and Performance] I am still very satisfied with this carb. The FSE110R has been hibernating in the garage for the last five months. Yesterday it started right up with choke (close to 50F air temp). Turned off the choke after about 10 seconds and it ran beautifully afterwards without a single hiccup. The quiet exhaust really make it a lot quieter. I turned the fuel screw to 1.5 turns to make it run a little richer in hope to bring the exhaust temp down a little. This is a great carburetor for the money.

Will not fit the Venom Grizzly 125.

Failed after about 3 weeks of use! Ended up putting my original carb back on. Lesson learnt.

Jai reçu une boîte déjà ouverte. Le carburateur sentait le carburant et de plus le filtre a air et les bolt etait manquant.

Great replacement for the Apollo 125cc dirt bikes. Bought 2 bikes. One never ran well and refused to crank at all after a crash. I replaced the carb with this one and solved the issue. So I bought a backup.
