I felt the same way, like I might have lost a little bottom snap. My belt was riding flush with the top of my secondary after I put the DP kit in, I don't know if it was the kit or just a coincidence but I remove a thick shim and it got some snap back although it sits pretty high right now (1/8 or so above) I may put the thick one back in and take out a thin one and try it. Any suggestions are appreciated.
Zig your secondaries are not all the same so on some u take out a thick one & on others a thin one u half to experiment what I try to do is get you as close as I can for overall rideing this not etched in stone that what works for one does not .works for all . Thats why thre are different weights , heluxes ,springs,gears to work with for rider weights & standard & sno pro sleds . Keep asking ?s & Ill try to help dial your sled for your personal rideing needs byoffcr
I have a completly stock F7 and my brother has the DP kit, gears, and a few other small things. He will holeshot my sled EVERY time by 3-4 sleds and grows to 6-7 by 1000'. Both are studded the same, with same suspension set up. Both sleds have the proper belt deflection-i.e. remove the proper washer from the center of your secondary. It does work! B)
You want 1 1/2" of belt deflection. (push down on the top of the belt between the drive and driven clutches, should only drop 1 1/2", if you havent messed with your driven clutch yet, you will probably drop 2 1/2- 3")
As of yet, in REAL world running the set up is 6-7 lengths in 1000' in our side by side comparisons, with MOST of the advantage coming from 0-30 MPH. B)
We haven't really seen any big gains way up top with this combo, but its way faster getting there!
I have almost always won the races in which I holeshot my victims, and with that is what this combo gives you.
After figuring the ratios that would be gearing to a numerically lower ratio (1.86 stock, 1.73 after change) which would give top end not low end quickness, so I am a little confused. Not that you are wrong but I just want to try to understand what is making it quicker (0-100) Usually if you want to drag race you would want a numerically higher ratio to help the launch. Thanks again for your help.
