  • Works great small but great engine
This engine is a great product.I swapped it out with my old broken engine and when I put the chain on, connected all the wires and put mix in the tank, it fired right up in 3 pulls. The oil I would use is 2t triax power sport oil fully synthetic engine oil . I have been using it for a year now with my last engine(it was’nt broken because of the oil I was using)and it works great with the new one.i did need to adjust the idle though when the engine was delivered if there were 6 stars for the review,I would put 6. ... show more

  • 50cc 2 stroke racing engine
The item was great when I got it. My first shipment I didn't get what I ordered and had to contact seller who responded very promptly and quickly. My correct item was shipped and received quickly. I have yet to install but looks as should be an easy process

  • Buyer beware.
Runs great, sounds very hot. Within 3 hrs of ride time the clutch issues started. Now revs very high before it moves. Im just convinced that I need to stay away from all Chinese junk. This was a replacement of the original dirt bike engine that was also chinese. It's cheap, but yeah, it's cheap....

  • Good runner!
Great running engine after leaning out the idle a bit. Gearcase was a little thicker and some minor trimming was needed. End result was perfect!
