yes and a smaller sprocket will give you a faster start up and larger sprocket will give you a higher top speed as long as your taking about the back sprocket other wise its flipped around.
Swap to a bigger rear sprocket or a smaller front sprocket. It'll lose a little top speed but be stronger uphill.
88cc big bore kit. thats about it. faster top speed can be achieved with a smaller rear sprocket.
run a smaller sprocket on the rear
Depends on if it's the older freewheel type rear hub or the newer cassette style rearl hub. Cassette hubs can take 9 tooth I believe, while the smallest freewheel is 15 or so.Depends on the hub. A cassette hub will go down to 9T. Standard freewheel is 16T, but there are a few that go to 14 and 15.they now make 8 tooth cassette hubs and 22 tooth sprockets to work for them. so 22 is the smallest out there so far
Change the rear sprocket from the standard 46 tooth to a smaller 34 or 36 tooth and the maximum speed will increase.
use 16/32 sprocket
Depends. The smaller the driver(the rear sprocket is) the heavier it gets to pedal. If you're strong enough to keep turning the pedals at the same pace, a smaller driver will make you faster. If you're not strong enough, or don't want to replace the driver for some other reason, then you have to practise pedaling faster instead.
to make a pit bike go faster you can take the baffels out of the exhaust, put a wider carb body on get a performance CDI unit , buy a larger front sprocket for the front and a smaller sprocket for the back and make shore the spark plug is clean and that it is a CR7HS (ngk) or can be CR8HS (ngk).
It's no guarantee that it will, it all depends on what you want to achieve. If you currently feel that you're strong enough to keep the pedals spinning like crazy, then going to a smaller sprocket means that the rear wheel will move more than before for each turn of the cranks - making you faster. But if you currently feel that pushing the pedals down is hard, then getting a smaller sprocket will only make that worse. If you want to be technical it's all about gain ratios.
For high speed you want a big chainwheel (by the pedals) and a small sprocket(by the rear wheel). But this is assuming the rider is strong enough to turn the cranks properly. If the rider can't turn the cranks at 80-100 turns/minute, he'd probably be faster with a smaller chainring/bigger sprocket.
Change the sprocket on the motor that spins the tires via the chain to a smaller size, that's a start. If it has a output plant purchase one with more voltage and add it on.
get a smaller sprocket or bend the reed valve opened a little bit more but not to much or it will bog the engine
