You can flip the rear axle for more chain adjustment.
Keeping a larger front sprocket will greatly extend chain and sprocket life.
I have the 350; I do really need the lower gearing for offroad. But, I had forgotten about the old flip the axle/adjuster blocks idea. I'll probably just trial and error on the sprockets until I get the min/max I can use with the same chain.
