  • Runs good, but...
Size: Type 2
Installed this in my son's dirtbike, the drive sprocket had so much play in it that it caused the chain to come off and break which broke the cover and magneto off.. serious design flaw. Can't say enough about the company though. I called Amazon and they put me in contact with the company and had me submit this same picture and 2 days later they were sending me a new motor. Prompt and professional. ... show more

Size: Type 3
Not a bad engine for the price it’s not one down for up it’s all down one through five gears but a great motor and since this doesn’t come with the owners manual The engine pretty much takes almost 1 quart of oil and the oil I use is motorcycle 4 stroke 10 W 40 for the 250 engine

  • Ssr125
Size: Type 2
Swapped it into an ssr 125. Mounted right up, only issue was the drive sprocket was bigger and had one more tooth. Ran it for a couple hours and now it’s worn in and fine. great engine!

  • Disappointed
Size: Type 2
Engine works. Started right up once installed. This is not 4 up, this 1 down and 3 up. This is also set up for an electric start. The description is wrong. I made it work on my daughters dirtbike though I specifically picked this because it was supposed to by 4 up which what she was used to. Had to reseal the main seal on the gear that turns the chain, it started leaking oil immediately. Though it is an easy fix, it's not something we should have to fix so soon. Disappointed. ... show more
