Then I tried the 13/10 front countershaft and 15 tcase input and am at about 80% (same length 420 chain), great in the deep snow on studs, but tends to climb out of the rut a bit too early as it hardly takes any rear spin for the front sprags to engage...

I may go back to 13/9 and 16 for summer (offroad) conditions. Put a 49 on for local dual sporting.

Great thread there, do you have to be a member for the pics to show up? I'm interested in gearing mine up so it digs more. Mine is 13/50, 9/16. I've only ridden it once so I only just learned that you have to gas it to bulldog it out of a failed hillclimb.
