I have a 110cc 1985 Honda ATC. Are there any close to direct bolt in Chinese engines that will fit? I know this is the ATV forum but figure somebody here may have done this. The cost of a rebuild it about 350-400 bucks at my local ATV shop. I am an Automotive shop owner and dont have the time to do it myself with the daily buisness and projects of my own. It would be easy to rest another motor in there and call it a day.

 

This would work( or engines like it): 110cc Automatic Engine Chinese Dirt Bike ATV Quad 152FMH on eBay!

The thing is you will more than likely work on it more after it's in than just rebuilding the org engine.
