Gearing 174 3"

I got a silber boosted 174 3in with a tki belt drive 63 tooth on the bottom 27 on top with a 7 tooth driver puts me about 2.33 on the final drive has anybody put a 28 or 29 Top Gear on and how was it on the bottom end?? 28 tooth puts me at 2.25.

What is the other number to figure in for the 7 tooth drivers?

I like what I got just want to tinker. I can't leave nothing along. I haven't touched it all yr. Indy Dan lighten and balance and sheaves is silky smooth running. A full beverage doesn't even spill over the edge and really clean.

Talked to Tom.

27 top gear
58 bottom gear

I just chucked a belt Sat. It split the belt about 2" and frayed the cord. It still worked just felt like a flat spot. 647 miles. You g to revy where there is gonna be alot of fresh deep deliciousness so I'm putting the 25 top gear back in for the chutes.
