Sorry I didn't get back to you 'til now but was busy with doctors visits yesterday for my wife and myself.
I had the valves checked at 55,000 miles and all was found to be in spec. As far as maintenance I have done almost all myself as far as oil changes, air cleaner maintenance and greasing the A arms which is almost impossible to do with the location of the zerk fittings and any other routine maintenance.
One problem I have had was with the coolant reservoir, it ruptured and dumped all of the coolant which left us stranded on the side of Rt. 81 in Pa. for about 4 hours, until my son could come and get us with his trailer (the only time it left us stranded). Then a couple of years ago I had it start leaking again, but that time I noticed it when I had just got back from a ride.
I did have to change the pillows on the A arms at about 70,000 miles or so. I had the the dealer at Phoenix, NY change the valve cover gaskets last year at about 109,000 miles. The rear wheel bearings were changed at about 65,000 miles when the rear tire was being replaced. The front wheel bearings are still the originals and still seem to be working well, although I keep checking them and thought this year I would have to change them and probably will when I change the front brake pads in the near future.
All in all we feel the Spyder has been an excellent machine and still "Love our Spyder".:thumbup:
