Update-
The parts are on order, the dealer expects to have them Tuesday, then another couple of days for him to forward them to me, I might have parts in hand by Friday - May 13. Only need 2 parts and cost is approx $25.
I am thinking of just removing the side case, cleaning the area and replacing the sight glass using some high temp adhesive. The failure rate seems pretty low, I don't think I need to overdo the repair.
Planning to take some pictures and post them for reference.
I really appreciate all the suggestions and support from this forum, especially ScooterBob & Kevin.
Later,
Terry
