Anyone buy this kit before? I just realized a 4 stroke with a centrifugal clutch would be perfect because i’m tired of manual clutching around my city with endless hills, I just use my bike for getting A to B. Any recommendations on 4 stroke kits/set ups? This is my current set up it’s looking pretty rough but does the trick

49cc is going to be very under powered compared to the 2 stroke a 79cc predator is 3hp and 7hp with modification that's going to be close to the china doll... Kings motors has the 4 stroke kit your looking for... AGK has the billet flywheel and other parts if you go over the 3600 rpm governor limit...

A GruBee or a Staton Inc kit is what I suggest getting



I've had my Staton Inc kit for 13 years.

From my experience, those little 49cc 4-strokes aren't very good when you have a lot of hills to climb.
They really lack power & will burn up the clutch if they're constantly climbing hills.

Also... The kits with the small metal primary case with a chain drive inside are the worst! Find one with a belt drive primary if you absolutely have to have a 49cc kit.... but they still have problems.

The only 49cc kit I've ever found that will last is the 7G Ghost Racer kit!! (But Gas Bike doesn't have them anymore). :(
