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