Hi Randy, welcome to the forum.
Did you know that hitting enter while you type does not finalize the post, it puts a line break in the text to make the whole post more readable?
I couldn't get through your first post for example ;-}
As you have learned in this topic already there is no such thing as a 80cc, most all are 66cc with the exception of the 70cc electric/pull start auto clutch Zelda with on-board power generation.
The company asked me to review a kit and sent me one all the way from China.
I was excited as hell but quickly disappointed.
It is a really fine engine that performs better than a typical 66cc, but I didn't have a battery in for the electric start so we tested it just using the pull start. Pfftt.. ~50 pulls and it broke and I don't mean the rope, the specialty plastic that actives it broke and their are no replacement parts.
So then I put a battery on and few more cool electric start rides on it and starter motor died, and again no replacement parts so it has sat useless for a few months now because there is no way to start it.
A great setup if they hadn't cheeped on those 2 crucial parts and I told them so.
If you want more details my topic with pictures about the adventure is here

If your goal is something that really kicks ass, start with a Grubee Skyhawk GT5 engine, give it an expansion chamber exhaust, and make it a shifter via a SickBikeParts.com (SBP for short) jackshaft shift kit.

That combo of parts
required the dual disc brakes if that is any indication of how quick and fast you can get with just a simple 2hp 2-stroke and gears ;-}
