I have a '95 R1100GS w/110k miles.
I am experiencing a problem with my tank that sounds
similar to John's.
When I bought the bike with 73k on it I noticed that
the tank mounting hole barely lined up with the slot
in the bracket and some force needed to be applied
(not a lot.)
At 82k my gearbox, which had always jumped out of
third at the worst times, finally crunched and refused
to go into 1st. I pulled the box, there were bent and
ground down shift forks and shifter shaft bushes
cracked. I had the tranny rebuilt at Marty's in
Torrance and popped it back on. The tank fit about the
same as before, some pressure required.
About the time of the 96k service I noticed the tank
would not line up anymore and I've been riding without
the bolt since. No amount of force by hand will push
the tank forward enough to line up and I've checked
the clearances all around. Nothing is fouling the
Interestingly I had an unused NOS tank in the garage
as a spare. One day I decided to offer it up to see if
it was any better. It was perfect! So I think the
answer in my case is that something happens to the
tank at some point and it actually warps, permanently.
Both my tanks are plastic, I assume John's is too?
I never had problems with the turn signal switches. I
had a solder joint remelt and become unreliable after
poor contact of the high beam switch caused heat, but
cleaning and resoldering fixed that.
If the switch can be cleaned up again and is not
cracked or poorly soldered anywhere that I would
suggest applying some dielectric grease to stop
