Advise on tki belt drive/clutch work

[Krause09]

I’ve been browsing the beltdrive for well, ever and I here mixed reviews but just noticed the 24tooth top gear which would gear down sled to 2.75 ratio. My sleds got 1500 mi with alpha skid, 165length and wondering if someone has ran This ratio? Noticeable gains?
Also sleds running stock clutching, looking at maybe trying to jump into learning how to get gains out of a kit, or are people just adding primary/secondary springs, arms and adjustable weights?
Sled is a 18 mtncat with early build Factory tune and diamond ti can, last year the sled would search for rpms ranging from 7800-8100. No visible cracks on primary or broken springs, ideas?

1500 miles and it's hunting for RPM...I'd be looking for worn clutch parts. Springs, rollers, bushings, excessive play, weight pin bushings, etc.

From the math a 7T 3.5p driver has about 2% higher gearing than a 8T 3p driver. Changing from a 2.63 ratio to 2.75 is about 4.5% change. Alpha track gets more traction = more load. So maybe there's some benefit there.

The 800 ctech makes peak power 7800-8100, right where you are. Personally Id leave your gearing where it is. If your sled "hunts" for rpm when your full throttle climbing, its of a secondary issue. Load from the snow and track transferred to the secondary trying to find the right gear. If I remember right the stock 18' came with e 48 degree helix, Id get a 44 degree with maybe a little stiffer spring. I think you'll be real happy. If you really want to get into the clutching game, get Cutlers clutching handbook. He wrote it a number of years ago, but the clutching theory is still just as valid with todays flyweight clutches.
