I honestly cannot notice a difference in performance after machined sheave and shim. Yesterday, I raced against a stock 2007 Grizzly. It has a ratio of 2.55:1.
The 07 has 26 inch Mudlites with some miles on them so fairly worn. They currently measure 24 inches tall (rear)
The 08 has newer Bearclaws that currently measure 25.5 inches tall (rear).
Both riders weigh about the same. I had some extra weight in a storage box than the 07. I’m going to say around 15 pounds. Both quads have about the same milage.
When we raced, he blew me out of the hole and had almost two full length of a quad on me up to about 45 miles per hour until we let off. We tried this a couple of times. Same result.
I have mentioned on here before that my quad has always been the slowest out of my group. We all have 07-08’s.
I realize that the tire difference is quite significant between these two quads. But, with me having a machined sheave and 1 mm shim is my machine running as good as it should?? None of my other riding buddies have any mods so I can’t make any direct comparisons there to personally see how other machines have improved after various mods. .My knowledge is from reading this forum.
Thoughts?
Thank you.
