50cc gy6 upgrading to 70cc

[jbot]

:sos: I have a peace sports 2010 model 50cc gy6. While riding it the stator literally sheered off on the crank shaft itself. Bla bla this much money to fix it from the place i got it from or how about a deal on a new one. Nope, defeats my purpose and pocket. Buying a new engine online, getting a 70cc piston head kit. Any suggestions, i'm doing it myself now. I've worked on cars forever and fixed 4 wheelers, lawn mowers, weed wackers, go karts, all types of engines and this thing looks simple enough, just asking what i might need or whatever. Not meaning tools, meaning other parts that would help for upgrade purposes or if you've done this before. thanks anybody.

Depending on if you're going all out on this 72cc kit or not.. you may want the following.

Naraku Jet kit 82-98

High tension coil

No rev CDI

Uni Air filter

NCY/DR Pulley Variator.

Slider roller weights (5g-7g)

High performance Clutch and bell

Gates belt

NOW.. if you're really going to dig into this, I would do it right the first time. Find yourself a nice BBK, they're not cheap! Enviormoto.com Partsforscooters.com 2 good places to start looking for a quality BBK.
Also.. I've used the '100cc kit' off of ebay from robotechlegacy (think thats the name) for an el cheapo option on a few bikes.
