Maddog, respectfully, how is the gy6 not a 4 stroke?

I actually have a spare motor 139qmb today actually swapped the clutch. the clutch fits the elite fine just have to use the elite nut. the variator I switched out awhile ago. the back part with the rollers in it only. my elite one was ate away. kepted my boss and the front part of variator. cover will not fit on with the other parts without spaceing the cover out washers or whatever. with the clutch didn't notice a real differance good or bad. does sound kind of cool around 5mph. def can't get the second part of cover on unless space and prolly file the inside. can grab a pic 2maro if ya want.

you wont see much gain out of the bigger pully unless you put on a larger belt i belive its the 554x18x30 for just bigger clutch pully. ounce the stock belt gets seated (after running) the belt will ride at the same height as it did with the stock pully on... 669x18x30 is for a larger rear pully and larger vari your gonna need some r's to get the belt to ride up a bigger vari though...

...if you have any questions with your GY6, let me know; I get the happy-ness of working on 150cc and 50cc GY6's everyday at the shop... I've seen them all. Quiet's are really common here in KY...

The funny part about the 50cc GY6's is in doing all the countless engine rebuilds I've done, I've learned that a LOT of "50cc" GY6 engines are really NOT 50cc's; I've seen 60cc, 75cc, and 80cc bores... The Chinese just use whatever sizes they have lying around at the time! That's why some 50cc gy6's run pretty good, and some are dangerously slow...

A good first tip is to check your valve clearance... In the case of the 150cc engines, ALL their exhaust valves become too tight within 1000 miles. This equals harder starting, (if it will start at all) and poor performance. 50cc GY6 engines need valve adjustments as well!
