Re: GY6 Origins?
Interesting thread. I've always just accepted that it was a Honda design without thinking very critically about that.

Doesn't Lifan have a knockoff of the engine designed used on all those small Honda 50-70-90-110cc singles from the '60s and '70s too?

What is a P engine?
The heads on the "P" engines (you can read this right off the engine ID number) are the tall heads and "should" have the big ports and big valves (at least on the 150cc and up size engines). The "P" head measures approximately 73.19mm from the deck surface ("bottom") to the valve cover surfaces ("top"). If you have a stock non-"P" engine that was on a US emissions equipped scoot, it is most likely that you have "small ports and small valves". Non-PAIR equipped heads "supposedly" had slightly larger ports than PAIR equipped heads.#N#If you have an aftermarket "big bore" head, it most likely has big ports and big valves. If you are interested in maxiumum performance the "P" head is really the best way to go (excepting costly 4V conversions) due to its larger ports, larger valves and improved port entry/exit angles. The cam chain cam be changed without splitting the case, Syn details how he did this on his 4V conversion.
