Review: Now it IS a direct bolt on for Oryxearth 105cc Lifan engine Minibike - Ordered this upgrade kit for my son's Oryxearth 105cc minibike before Christmas in Dec. 2025. I read the other reviews and watched the videos that said it does not directly bolt on and will interfere with the stock fuel tank. I can report that they have changed the design of the intake manifold tube. Instead of a bent tube welded to end plates, it is now a cast stainless part. More importantly, they have changed the geometry so that the screw cap of the throttle cable does not hit the stock fuel tank anymore. I think the carburetor now sits a bit farther out away from the engine. As a result, the air filter sticks out a bit more than the previous pictures show. The entire assembly bolts on without interference and I was able to use standard length Allen hex keys to tighten the bolts without problems. The easiest way to remove the engine governor is to remove all of the chrome plated claptrap and springs that are attached to the back of the engine next to and below the old carburetor. To remove the long arm attached to the shaft coming out of the crankcase, use a 10mm wrench or socket. It is hard to get to, but once the nut is loose, the arm will slide off the shaft. Other people open up the crankcase and remove the shaft, the gear and the governor, but then you need to plug the hole in the side of the crankcase where the shaft went through. We just left the shaft poking out of the crankcase and left all of the internal governor parts in place. They don't do anything anymore after removing all of the external governor parts, so they are just along for the ride. I do agree with another reviewer that the bolts that attach the manifold onto the engine are a bit short. I disagree that they only have one turn of engagement. It is more like two to three turns, but that is still really too little. They should really supply longer bolts for this. Only other negative is that you do need to purchase about a foot of fuel line to hook it up to the fuel tank. Seems strange that they include the carburetor vent tube, but not the actual fuel line. Also disregard the review that says you need to get another throttle hand assembly and cable. The supplied throttle cable worked perfectly with the stock Oryxearth hand throttle. You do need to take it apart to install the new cable. In our case, one of the bolts was stuck and we ended up drilling it out and replacing both bolts with better M5-16 socket head cap screws. Getting the throttle apart to install the cable was actually the hardest part of our install. The fantastic news was that once installed, the engine started right up and idled OK (we live near sea level, which probably matters for this). There was a little throttle hesitation when slamming the throttle wide open. I may try to play with the mixture and idle screws to see if I can improve that. So, I can really recommend this upgrade. With an exhaust header it really livens up the engine. The stock Oryxearth 105cc minibike topped out at 24mph because of the governor. Disabling the governor and installing the exhaust header, new racing plug, and this carburetor kit, the minibike gets to a solid 35 mph, which is a 46% increase in speed! The above performance was with the provided inline fuel filter. I decided to install that to somewhat limit fuel flow into the engine so it does not rev too high. I don't want the engine blowing up with my son on it. The stock governor limited the engine to 3,600 RPM. With the increase in speed we got, it must now be reving to 5,250 RPM, which is plenty high. Any higher and I would worry about the flywheel or connecting rod letting go. So, beware of overtuning this engine without internal strengthening (stronger parts are NOT available, unless someone else knows a secret source).

### ⭐⭐⭐⭐ Fits/Works Well
*by D***N on February 20, 2025*

Installed on a 2024 Phatmoto All-Terrain. Carb works well. Started right up without any initial adjustments. A variety of main jets are included for proper tuning. Governor must be deleted with this kit. Air filter protruding a bit of a bother at 1st, but not bad. Any performance increase has yet to be determined as a Torque converter & gearing changes are still being addressed. No air/gas leaks yet. However, was missing bottom plate between top of slide & throttle spring inside carb which was annoying & a replacement had to be fashioned.
