I've got a '95 R11GS with ~31K miles on it. Since I bought it this past spring I've put 7K miles on it. Now it is developing lots of little bothersome gremlins. Maybe someone out there can comment on a few of these problems.
- When the gas tank is removed, it doesn't want to go back to the original position where the bolt can be put back in. I have to use a wratchet strap to pull it back into position. It appears that the fairing pieces in the front are prohibiting the tank from going forward enough.
- I've been noticing a lot of engine ping when really hammering down on the throttle. So I used some Sea Foam yesterday with a refill of 93 octane gas. Now the fuel sensor on the RID doesn't seem to be moving and I still have the engine knock.
- Went on a group ride yesterday and was told that my brake light was always on. I found that the front brake lever was not returning to the fully out position leaving the brake light switch on. I tried some WD40 on the hinge point but this did not help. I have to remember to push the front brake lever back out.
- Finally, my gear position-neutral switch seems to be going out as the position on the RID is all over the place while riding. This seems to be a very difficult replacement. Anything I can easily check before pulling the swing arm?
Any suggestions to all or any of the above will be greatly appreciated. Feel free to separate out the individual items. Thanks!!
Classic Barn Bike Syndrome
You need to get your bike to a good BMW mechanic familiar with your bike and have it gone through. The brake problem is probably a cable seizing up that needs replacing, it could be other things. The RID problem with the gear shifter, that is a common problem with that generation of BMW's. The engine knock, could be in the TB synch - special trick to pre 96 oilheads, then again what gear and rpm does it start knocking at? Tons of answers for that. Sea Foam, Chevron total fuel system cleaner works a lot better for me. If you have oil that you can see through on the sight gauge and after using the cleaner it turns the oil "BMW BLACK" you need to change the oil its full of crud. The tank, something must be wrong with the mounts. A good BMW mechanic can find all the faults, plus some more. Grease in the driveshaft may have turned to wax, the throttle bodies are sucking air through age cracks, etc.
Been there done that, probably do it again
Sounds familiar - kinda
The other poster is correct, if you don't have a club member familiar w/ the gs, a bite the bullet trip to the technician is worth it.
The throttle bodies can start to cause poor running;where the butterfly valve pin goes through the casing, it wallows the opening and allows air to enter. I forgot what to spray on them that would make the engine hicup if this were a problem. Darn. Also, did you take off the emissions canister? Could it be clogged?
I don't think you should have to ratchet your tank on. Is something binding underneath? I know its a pain to wiggle the rubber buffers onto the plastic and the tank at the same time, another pair of hands can help there.
The brake is hydrolic of course, perhaps you have some corrosion due to a small leak at the master cylinder. I would take a careful look there. While discussing brakes, once you have one rubber line fail, just buy the speigler line kit and replace them all. I found out the expensive way that deterioration comes in stages! Still with the brakes, you can easily rebuild callipers with a kit from the dealer, don't be intimidated. Also, don't get your fingers in the way when cleaning out the passages with compressed air!!!!
My neutral light has a mind of its own.
