    Hello everyone, I hope you all had a good Thanksgiving. I need some advice on choosing the right sprocket for my 80cc MB with stock 44t sprocket. My bike has a centrifugal clutch and pull start, so pedaling is no longer an option. I would like to make my bike take off faster from a start, what would be the best sprocket for that application? Any help would be greatly appreciated, Nelson. :)

    Go 50 tooth. More teeth and bigger sprocket = quicker low end... It will come as a sacrifice tho, because your bike won't be as fast, top end...
  3. i have a pullstart and centrifugal clutch and i can still peddal but i dont much.
    i raised my enigne in the frame a few inches and changed my peddal crank arms from 8"s to 5"s. You could get a larger sprocket or put a thinner airfilter and open up your exhaust to more freeflowing.

    48 tooth

    Get yourself a 48 tooth sprocket. Its a good choice with a ratio between speed and power. I can get my war wagon up into the low 40's without too much vibration.

    Thank you all for your response, I will give that 48T a shot and see how that goes. I can always change it later. :cool2:

    What is the best place to find a 48T sprocket for a decent price? Any help would be appreciated, Nelson. :)

    Sprocket choice

    Hi Nelson,
    I have two bikes and working on a third. Both mine have pull start and centrifugal clutches. I notice I lost a bit of pick up on take off too but I have chosen to stay with the stock 44 tooth as they seem to work ok for me and I figure it it's not broken, don't fix it.
    You can still pedal start your bike just as if you didn't have the centrifugal clutch. You just don't need to operate the manual clutch otherwise. If you don't need a good top end speed you have already received good advice about 48 and 50 tooth sprockets. In the city here where I stop and go so often I don't need top end speed. Good Luck and welcome to the forum, lot's of good advice and helpful people here.
