pay no mind to the haters. the gy6 is a honda clone. period. sym and kymco build dio clones, yet nobody seems to hate on the 2-smoke honda clone. the gy6 shares trandmission components with the af16 (variator, clutch bell, rollers, possibly the clutch) and the gy6 powered scoots CAN be very nice and reliable. the problem is often the quality controll (or lack thereof) in the chineese factories. some brands of gy6 clones are better than others, most all of them use very cheap plastic for the body panels, but replacement panels are cheap accordingly.
the gy6 150cc will bolt right on, or they make a few different big bore kits. my friend has an 80cc kitted gy6, it's a nice ride, and decently quick, no more hill problems, great gas milage.
here's some downright NASTY gy6 action for you:

in the immortal words of DAC, "it's not WHAT you ride, it's THAT you ride."
i move to start a "gy6 and gy6 clone" section, as the gy6 qualifies as part of "the rest of the 50cc honda lineup" mentioned in the logo. we have very little tech support for the four stroke stuff.
*edit* Uhhhhh.... so where in northern michigan are you???
