I've never seen one. I don't think they make them.

You can make one, take a 14t, and grind off 2, but leave at least 4 full teeth between! Bob

A bit of advice, might be in order. Bob's advice is how them TQ guys change gears in them quick change thing a m bobs. While you can buy 12 tooth sprockets, made special for us car guys. You need to know that as the front sprocket gets smaller that chain has to wrap around a smaller and smaller radius putting a lot of stress on the chain and sprocket, on top of all that the smaller the sprocket the faster the chain has to move to get around it, with a sprocket that small the chain speed is reaching super-sonic, not good for a chain either. We learned a long time ago to run as big of a front sprocket as we could to get our ratio and if it takes a 12 tooth sprocket to get it we would probably just go up two or three teeth on the rear sprocket or maybe go to a different transmission gear. We usually carry 3 different chains to the track to make gear changing easier for us. Honest Dad himself |

Not being a smart guy, but what is the difference if you run a smaller front sprocket or were to go to 1st gear. Wont both of those spin the tranny output shaft faster? Trying to get to a 13.5 final ratio...

Smaller radius = fewer teeth = less contact surface, more localized stress on the individual links.

It's a kinky chain thing "Most people just don't understand". For the Center you are probably OK BUT it will shorten up chain life quite a bit, that stuff just doesn't like to be kinked up. Bigger is better. Did you ever try to take a lug nut off with a 1/4 inch drive ratchet? Honest Dad himself |

You're thinking of it backwards. As you go up in gears in the transmission the output shaft spins faster. That's why you'll be going faster in 5th gear at X engine RPM than you would be in 1st gear at the same engine RPM.
