Bull, I think (but I could be wrong) Polarisrocks was possibly answering the question of the original thread poster who is contemplating a larger change than what I am. I appreciate your info though......
In my case, 19/41 is my stock gearing, and I felt the need for a bit more efficiency to turn that 155" 2.4 track faster in the deep heavy powder when the runs are long. We ride from 6,000 to 9,000 'most" of the time. I typically don't go for a big run at a hill, often I'm turning 90 degrees into a slope with little run, so I want to know that I can pull hard for the duration. Between one tooth larger on the driveshaft sprocket, and the fact that it is a lightweight sprocket, I just had my drive clutch balanced, and Carl's is throwing a lighter Holts suspension in as we speak......I think (hope) I will get what I am after. We'll see soon.
