Chaincase gearing.. 2020 450xcf and ARO 137

[Klutch]

I previously had this kit on a 2018 350xcf and found that motor liked the gears swapped(lower geared, I swapped the gears, so 17 up top and 18 on bottom) the 350 revs higher, so figured that was the reason. But now on the 450, should I swap them back to stock position?

I had the gears swapped on my 17 factory edition and the ARO 120 - it was way better running the shorter gearing. I'd think on the 137 that would be even more the case.

I would think a 13 front also...

I run a 19 Husky FX450 with an ARO 137. 13T countershaft sprocket and stock gearing seems pretty good. Maybe 1st could be a touch lower but it's close
