Af16 gearing ?

Post by BAMFChuddy »

Hey everyone! I am looking for primary gears for my motor. I have an af16e from a SA50 "S" but has been derestricted to basiacally being an "SR" so far i can reach around 50mph. With a variator, rollers, oil plug and yellow contra. But i would like to get gears for it so i have alot more speed off the line. Id be fine with getting the speed down to around 35mph if i can get there fast.

So i would like opinions on where to buy them from and what would be the best ratio to buy. Thanks in advance!!! :geekdance:

Also does anyone have a spare af16 air box they want to sell? Lmk

Off the line clutch grab is set by the clutch center spring + clutch springs, if you can afford the stage 6 clutch get it, use the harder springs that just drop in then dial it in with a allen wrench and you are set...

Greetings:

Stock ratio is 12:1. Are you saying you've seen 50MPH on those?
9:1 gears on a stock engine can see close to 50, but I do not believe the 12:1s will ever see 50.
Perhaps some previous owner has already installed 9s?
Everybody who wants gears is going taller. As far as I know, no one makes a ratio shorter than stock.

I'm curious to know if you're really getting 50 mph on stock gearing. Might want to check your GPS :p
Vt cycles sells 9:1 gears for $50 or you can buy them from chopchop 123 (believe that's taz?) on eBay for $40

take the rear kick cover off and count the rotations of the clutch bell with one turn of the tire.

That will tell you what ratio you have now.
