Upgrades?

Just finished my first build. Its a 80/66cc 2 stroke Grubee Skyhawk gt5a. Everythings stock and I can get around 25-30mph. What are some upgrades I can do to raise top speed other than different sprockets. I live in a hilly area and can't afford to sacrifice torque.

Save your money. Those China GIrl kits are not worth upgrading.

The single best upgrade for me has been a good expansion chamber, not the small muffler type but the type with a longer head pipe and large body. I made a silencer from the stock muffler, mine sounds like a yz125 but quite.

Match ports, polish, billet intake, and expansion chamber

The biggest upgrade would be a shift kit. You'd also want a techometer to go with it.
