125CC Semi Auto Engine Motor Kits Horizontal, Single-cylinder, 4-Stroke, Air-cooled Electrical Start Engine 4 Speed W/Reverse for Go Kart ATV Quad Buggy ATC70 90 CDI (US Stock)

The media could not be loaded. Installed on my kiddos two seater coolster go cart. Previous motor had a bent valve. Over all easy install, required some shims to align the sprockets but easy fix. Have had it on there for about 2–3 months now and it runs perfectly. They ride often so I would say it easily has 25-30 hours on it and I have no complaints at all. Good little motor, 3 speed trans shifts as it should and a top speed of about 38 MPH. Torque is good enough in 1st for the soft sand and getting around hills and rocky trails.

Seems to be well made, has all the wiring but no directions or schematic

Purrs like a kitten. Easy to install.

Had a difficult time installing this engine in my go kart. Once installed and finally running we used it for only 3 weeks on and off. Engine started cutting out, then the transmission wouldn't shift. Soon after, the engine died and I can't get it out of 2nd gear. Very cheap engine and is not worth the time spent trying to get it to work.

Seem to be a good engine haven't put any hours on it much at all yet put I think it's fine.

The media could not be loaded. Easy installation exactly what they say 5 stars!!!

it works good put it in my dbx1 140cc tao tao it fit perfectly.

Engine started up flawlessly and runs very strong! No regrets thank you
