3rd gen R sprocket combos

[partsmaster]

Curious what sprocket combos (14/40, 13/38 etc) you guys are running with your liquid 250Rs, particularly the big bores/strokers with 21-22" rear tires. Thanks!

I RUN 13/39 ON ALL MY 250R'S And all the big bores too.... thats what they make gears for,,,

Well thank you, I was just curious what the pros are using and I was hoping you in particular would answer!

15/35 or 14/35 for ice racing

With my R being a basically stock engine with intake and exhaust upgrades I have been running 12/39 sprockets. However, I just sent my cases out to get machined for a 350 big bore build...So I think I will probably end up gearing back to stock 13/39 gearing..... Running 20" rear tires
