Bike is getting new cylinders & new gaskets. I have a high level of confidence in the ability of the local shop here to assemble this correctly. As to the parts themselves - time & mileage will tell. Spoke to the tech, the Service Mgr. & the owner. All great guys & nobody pounding sand here. Bike will be ready by Monday.
Pistons & all looked good - about what you would expect for 17,000 miles. Nothing out of the ordinary except both cylinders had slipped. Back jug more than the front & was leaking more substantially. About a fingernail width on the back & barely perceptible on the front. Front had just barely started leaking.
Pics below for those who are interested:

New gasket on left, old one with "ears" on right

Was told these new gaskets were first available last week. Appears to be a composite - graphite colored

Side view. Old gasket spreads apart & is made of metal. New gasket is pressed together.
