Re: KC's 68cc 4-stroke 4-speed soft tail
I have to say that the Honda clones have several advantages over older Honda engines that, despite the country of origin, make them a better choice.
The Honda ATC/TRX 125 engine is a good one, but in the interim since it's was available new, ( this is the kicker, try to find a new OEM Honda 125 TRX engine..) the Clones have made several improvements. One being the clones are all 12 volt systems with big current outputs. They use a lighter and better designed engine crankcase casting that makes their engines lighter for the same displacement size. They also support the camshaft on two ball bearings, plus the cam chain tensioner is simplified and improved. The overall cam profile is designed for better performance, and sometimes the clones come with larger valves and the ability to easily add an engine oil cooler.
They are a bargain for what you get.
