I assume that with modifications it can be done, I'm doing an engine swap on something else now. May need some fabricating, welding and definitely wiring.
What's wrong with the stock motor? If you put some money and time into it It can be just as fast if not faster than that 150 motor, a lot more peppy, and a lot more fun! I eat 150 gy6 all day.

It probably still has the restricted variator. Take that out and put in six gram weights and it should go 45 or so.

Mine didn't have a restricted boss drive when I bought it, but I've heard that you have to buy the new one without the weld on it.
And if the exhaust has an emissions tube then that will slow you down too. Not many had it, but mine did.
Derestrict that variator, make sure your exhaust isn't with the extra tube on it, and even with the stock 8.5 weights, if they're not destroyed, you can be getting 45 plus.
@hieumait, how many miles on it?
I would suggest taking some time to read the threads in this section of the forum and seeing what many of us do with our s9s. Another great place is the 49ccscoot forums. The tech section there is very nice and a lot of people there can help you if you give them the proper information.

Variator is part of the transmission, aka cvt. It holds the roller weights. It's a very important part of a scooter motor. No matter how awesome your engine is, if your variator and rest of the cvt is not in proper working order or tuned correctly, it will suck.
