Guaranteed to Get the Right Engine for Your Buggy
Read below and if you are still unsure give us a call and we will make sure that you get the right engine for your buggy, GUARANTEED. WE ARE THE BUGGY ENGINE SPECIALISTS!!!!!!!!!! Nobody in the USA knows buggy engines like we do!!
Does the Engine fit your Buggy?
This engine fits most Chinese-built 150cc buggies built from 2000 to around 2011 or 2012 with or without reverse. These are buggies with no reverse such as the Yerf Dog Spiderbox 3206 and 4209 and the yellow Tomberlin Crossfire 150 or buggies with the external reverse gear box such as the older Kinroad, Blade, Carter Talon, Twister, SUNL, ROKETA and many more. If you have an external reverse you simply remove your gear box from your old engine drive shaft and install it onto your new engine drive shaft.
Does Your Buggy Have an Internal Reverse?
If you have a newer buggy such as a TaoTao, Explorer, Scrambler, Raptor, Falcon, Kandi Spider, Tomberline Crossfire 150R, Baja Dune 150, American Sports, Trailmaster or UTV such Yerf Dog Rover CUV or Bull Dog Pup you will need one of our internal reverse engines for buggies.
Does your model have internal reverse?
This engine will work, but if you have an internal reverse engine, you will need a compatibility kit. Contact us for more information.

If you feel there is a problem with the engine, please contact us for warranty assistance. Do not return your engine, it will be refused and returned to you.
If you have the Crossfire 150R, this engine fits but is not Plug-n-Play. You will also need the engine conversion kit to make it a bolt-in installation.
Real 150cc (57.4mm Piston)Guaranteed to be a true 150cc
Recently many 125cc engines were pushed onto the market as "150" engines. Everything on those engines appears the same as the larger version, but the cylinder and piston inside are smaller. The engine you're looking at now has the 57.4mm bore, which is 149.75cc.
Be sure to read our article on how displacement affects your power.
Large Valves for Higher Top-End PowerArrives with Large Valves Installed
The large 27mm/24mm valves allow the engine to breathe better at high RPM, allowing for higher top speeds. This is a very noticeable improvement if your original engine came with the smaller 24/23 valves.
8-pole charging upgradeAlso includes STAGE 1 Electrical Upgrade
This engine comes from the factory with our S1 Electrical package, which generates more electrical power for lighting and charging the battery more rapidly.
Depending on which frame you have, you may be able to use the kickstart internals installed on this engine if there is enough frame clearance.
If you have a HOWHIT engine, you also need the correct exhaust mount adapter.
Our engines come with debris blocker on the inlet of the CVT, instead of the original boot shown in the picture. The original boot wasn't designed for dusty conditions and clogs quickly. This has (in our experience in speaking with many owners) lead to prematurely failed clutches and flat spotted rollers due to heat build up. Also, this engine does come with an intake inlet manifold, although none is shown in the picture.
No returns on engines.
Please do not return your engine. It will be refused and returned to you.
Engine is shipped DRY with no oil.
Be sure to add 750ml of 10w40 to the crankcase and 120ml of 80w90 to the gearcase before starting.
If you have external reverse
This engine comes with the short transmission shaft common on Yerf Dog and Crossfire 150s. If you have reverse you'll need to install the correct reverse shaft into the transmission. You have a few options:
1. You can use the shaft from your original engine. (45 minute install, full instructions)
2. You can buy a new reverse shaft if yours is damaged. We carry the right shaft for your vehicle, ask us beforehand if you need help with this.
3. OR we'll install the shaft for you here before shipping the engine. You must buy this service to cover labor: Transmission Output Shaft Installation Charge
Everything under the engine's covers and plastics is included and installed, this is a complete unit. Starter, stator, and intake manifold arrive bolted to engine. CVT transmission is fully assembled and cover installed. All transmission components are assembled and cover installed. All drain bolts and internal oil screen are installed. Valve cover installed.
Carburetor, exhaust, ignition components and charging parts are all sold separately.
Remember to adjust valves after break-in period.
About Oil Coolers:
Our engines do NOT come with provisions for oil coolers, and never will. We've always advised strongly against the use of oil coolers on the GY6, and we refuse to offer them on our engines. We've seen too many instances where a cooler line bolt vibrated loose, dumping all of the engine oil and causing a massive failure. The perceived benefit isn't worth the risk. Oil coolers on the GY6 solve a problem that doesn't exist. Follow regular maintenance intervals, invest in a UNI Air filter (and keep it oiled), and your new engine will last many years. Coolers provide a false sense of longevity benefits, and the only proven result is the added risk of unexpected massive failure.
