Was planning an engine rebuild for my 1985 Honda ATC 200s and after pricing out all the parts to build the engine I wanted it ended up being about twice the price of this engine. It shares the same exact mounting points for any 80s 185cc – 200cc Honda and bolted right up. Had to retrofit a clutch since the original engine was auto clutch and also a battery and starting/charging circuit as expected. Bike now has electric start, reverse and twice the power it used to. I have put this engine through its paces for almost a year with no issues at all. It will spin 22” knobby tires in reverse on dry asphalt and will stand the 300lb bike on wheelies with no problem. Clutch grab is very smooth and runs smoothly at all rpm’s once tuned correctly. Very torquey and seemingly reliable engine for the price.

The packaging came pretty banged up but nothing was damaged. It was an easy swap except my clutch cable was too long so had to get a shorter one but all in all worth the price. 👍

Motor runs great and had no real problems with it coming damaged or anything. The only gripe is that it came wired wrong, took us a bit to figure out that they didn’t match the color to the correct wires and the booklet that came with it wasn’t too helpful, other than that I would recommend.

Lot’s of low end torque . Perfect fit for my application which is my Honda 200x 3 wheeler . Only problems were the clutch cable mounting location and the Bottom brace on the frame .I am happy with my purchase .It would be helpful if it came with a parts diagram with part numbers so i could find parts when and if i need them

Hard to believe that the clutch won’t engage when it’s a new motor. Not happy that I have to open up a brand new motor to see why it’s not doing what it’s supposed to be doing. Not happy

As of now it won’t fit on my atv, so I have to do some custom fitting to the frame before I can even mount it, but I guess it looks nice sitting on my stand, atleast I know it won’t break down on me sitting there

Matched my exhaust and carburetor perfectly, that never happens for me usually. Expected to have to modify something but all the pieces of my frankenquad came together nicely. Only thing I can’t figure out is the reverse indicator light. I’m sure it’s me that’s doing something wrong lolol. Neutral light works just fine. I have another one I’m building so I will be ordering another soon. The reverse gear was a must have. Couldn’t be happier.
