Will this do it?

hi, I'm new here and I'm looking for some performance. I want to know what I can do to my 66cc china girl to get 35 or 40 mph. The upgrades I was thinking about are as follows: thatsdax high performance carb, X chamber muffler, 70cc hi hi high comp head, and 36 tooth sprocket. Thanks.

Check out the racing subforum. They know all the tricks. If you plan to go that fast, make sure you budget for strong wheels, disc brakes and a very strong headlight. You don't want to hit a staggering pedestrian on River St.
