there are a few things to do.
replace the CDI with an performance CDI (5 wires DC 6 wires AC)
check the variator for a washer on it, the washer prevents the belt from going to the top for high gear. you can also put in lighter roller weights.
check exhaust gasket to see if it is restricted.
most state laws do not allow 49cc scooters to exceed 30mph do this at your own risk.
can i make a raptor 50cc any faster. can you bore cylinder out and get more power out of it
All else being equal, a bigger engine will make a faster vehicle.
unless the current cable doesn't move freely - no.
Hard to do. Its oly 50 cc. Buy a bigger bike.
It will not really improve your top speed but it will give a better growl and have better acceleration and power on the hills.
Buy a new pipe
There are a variety of different companies that make 50cc mopeds. One of these companies that makes well known 50cc mopeds and scooters is Linhai Yamaha Aeolus.
Not!! you have to go more then 80 kph to make it work and then the pressure wil open your membrame and then your going slower instead of faster.
THATS NOT A QUESTION, A QUESTION WOULD BE WHERE CAN I GET 50cc POCKET BIKE PLANS ? OR WHICH POCKET BIKE FRAME IS THE BEST FOR 50cc, OR WHICH IS THE CHEAPEST TO MAKE ?
No. Removing a restricter on a scooter's carb will make it faster but decrease mpg. If you are talking about a restrictor on the exhaust, then most likely you will increase mpg, but boy is it LOUD.
port out the cylinder head, replace the muffler, get a performance air filter, get a smaller sprocker for the rear wheel,and take off any electronics that you dont need.
you use the kickstart usaully
