You're right on. I measured the new washer with a dial caliper, and averaged .085 at the outside edge over 4 or 5 readings, using the depth gauge part of the tool.
Incidentally, some here have expressed that their local dealer tells 'em the parts are back-ordered at KTM. Local Birmingham dealer told me they could get it in 2 weeks. Donnie Graham (Graham KTM, Senatobia MS) was placing an unrelated order with KTM, and added this kit to his order and it came overnight.
Donnie is a good one. But he's ruining my unflattering opinion of motorcycle dealerships...
