Kandi 110 engine swap
 

I just picked up a Kandi KD-110GKG-2 to give my 5 year old for Christmas this year.

From what I'm reading the engine on these units were trash. The original owner couldn't get the stock engine to run at all so he had a 212cc Predator engine installed.

I want to replace the predator engine with something that has reverse and electric start (including charging system). The kart already has a gear shift lever as well as key ignition.

The question is, what is the best engine for under $400 for this buggy? I'm looking for something that varies speed well and is reliable. I need the engine to be reliable for 3-4 years. I'm not worried about the amount of fabrication. I've got plenty of time between now and 12/25. :D

Currently I'm looking at the automatic 110cc or 125cc chinese engines. Suggestions?

Slowly making some progress..

Pulled the engine and took the swingarm off the kart.

Unbelievable amounts of grinding..

Butt-weld and more grinding. I didn't trust my welding enough so I wrapped this with some tubing and welded over it. Pictures later.

My son has had his Kandi 110 buggy for 2 years and have had no issues with the stock engine. It's been a great buggy for him. Sorry don't have any experience swapping the original engine to a predator.

neat thing about it is that im pretty sure down the road you can throw a jug, head, crank n rod/piston at it and make it a 125 or 150. never measured the jug/piston on my daughters, think it was a 110, but turning it into a 150 was a piece of cake.
