I did my 3750 mile maintenance 190 miles early today.
So far here are the problems I've had up to now:
Several of the little light bulbs in the running lights and the speedometer have burned out. I replaced them with Sylvania bulbs.
The chrome plastic left rear turn signal and an internal failure that allowed the ground wire to loose its contact with the bulb socket. I replaced all 4 signals with old style metal bullet signals.
The covering on the seat came loose on one side. I re-glued it to the seat frame.
One bolt loosened up and after adding a drop of blue Loc-tite I retightened it.
The hose clamp on the rubber fuel line from the pump developed a leak. Tightening the hose clamp fixed it.
The only thing I've found that I think is marginal is the chain.
Although I keep it lubricated and adjusted it once it does have quite a bit of looseness when I try to move it from side to side.
If it didn't have this side to side looseness I think it would go for another 4,000 miles.
All in all I think my bikes reliability has been much better than I expected and I am definitely a Happy Camper.
