Went yesterday and picked up the '99 1100gs.
The good; I't's a complete bike , 47k miles , ohlins , hard parts , (tranny and steering), has a huge fuel tank , I think GSA , PIAA aux lights, oem side cases , Hepco Becker top case. And a 2 headlight setup I haven't seen before, an odd lower front fender, and a 2 taillight system I haven't seen before.
The bad; No Tittle, has been sitting outside for at least 2 years, (and hasn't been started since 2018) the cases are all sun faded, 1 side case has a broken lock, (works with screw driver) , front shock is leaking
I looked in the tank with a flashlight, and doesn't look to bad , I haven't pulled the pump plate where I can really see what it looks like.
I looked at the 1100rs, it was really rough, broken levers , clutch and brake, broken plastic, no seat 110k miles and also no tittle. I didn't buy it. Looked like it would cost more than it is worth to get it running and titled.
