GUARANTEED FIT FOR YOUR EXPLORER BUGGY GO-KART.  New GY6 150cc Internal Reverse Buggy Go-Kart Engine.  This is the exact replacement engine for your vehicle. 


WARNING:  If you are considering purchasing a GY6 engine from eBay, Amazon or any other USA seller you could receive a 125cc engine instead of a 150cc and you would never know it.  Since 2006 China has a history of sending GY6 125cc engines in place of GY6 150cc engines. The engines look identical from the outside.  BDX Performance is the only engine seller in the USA who disassembles and visually inspects engines to ensure that they are 150cc.  We unbox and dissemble approximately 50% of every engine shipment that we receive as we convert these into 175cc engines.  And we have caught some engines that are GY6 125cc being sold as GY6 150cc--see below.  Don't play Russian roulette with your money.  Get a guaranteed, verified and certified GY6 engine from BDX.  The cylinder on the left is an actual cylinder that we pulled off of an engine that we purchased as a 57mm GY6 150cc engine and was actually a 52mm GY6 125cc engine.  

Convert Your New Engine into a Powerful Racing Engine

More CC means More Power:  We can also convert this same 150cc engine to a 175cc or 184cc racing engine giving it more horsepower.  Read our article on how displacement relates to more power.

About Oil Coolers:
Our engines Do NOT come with provisions for oil coolers. We've always advised strongly against the use of oil coolers on the GY6. We've seen too many instances where a cooler line bolt vibrated loose, dumping all of the engine oil and causing a massive failure. [b]The perceived benefit isn't worth the risk.[/b] 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 even decades--we've seen it many times. Coolers provide a false sense of longevity benefits, and the only proven result is the added risk of unexpected massive failure.
