    I recently found a 1995 BMW GSPD that a co-worker had sitting in his garage for a few years untouched. He purchased the bike new in late 94. After a cycling accident he parked it and has not ridden or started it in 3 or so years.

    I picked it up and have begun prep to get it back on the road and am looking for pointers as BMW motorcycles are new to me.

    So far I drained the gas, replaced plugs and battery. I was able to start and run it this morning fairly easily. It smelled bad, I assume partly from all the spider webs... The left cylinder seemed a good bit hotter than than the right, is this normal? Also the blinkers and horn are not working and the neutral light is not comming on. High and low beams are working.

    I will be changing the engine and gear oil tomorrow, the air filter looked pretty new.

    Once I get that set and run it for a while what else should I look into? Any advice appreciated.
    The bike has 28k miles.

    Old gas leaves a sticky residue behind even if removed. Removing the float bowls from the carbs and cleaning would be a beginning. If the carbs were removed they could be cleaned better. Some gasoline additive will help.

    The bike is really at this point in an unknown condition. I don't suspect problems with the valves or expect them to be out of adjustment but I think it prudent to adjust the valves.

    The engine oil, gear box oil and final drive oil should all be changed several times. The brake fluid should be changed. The fork oil should be changed.

    All these procedures and more are described in several manuals available. There's Haynes, Clymer and the BMW Shop Manual. Take your pick. Buy one.

    What disston said. Give the carbs a good cleaning. Definitely disassemble them and clean them well. Idle circuit passages clog easily and just dropping the bowls and giving them a quick spray isn't enough to do it right. Drop all the fluids and replace them. Regrease your swingarm bearings, and steering head bearings. Get it running, put 1000 miles on it or so and change at least the motor oil again. That should at least get you going. Then just put all the miles on it that you can and see what needs attention.

    yep, what they ^^ said.
    one cylinder getting hotter than other ? Warning, these bikes do not like sitting still adn idling, its not good for em. Dont let it sit there and get too hot without at least a box fan blowing on the engine and still only sitting still for a short time

    Congratulations on your find!

    I'll just mention that you should also change a some rubber bits, such as:

    1.Speedo rubber boot that goes into the tranny
    2.Fuel lines, and possible add a couple on inline fuel filters
    3.Tires

    Take a look at the rubber pieces of on the swing arm for cracks, etc.


    +1 on removing the carbs for a deep clean.

    Good luck,
    Mario

    Thanks, the gas smelled a little off and was tinted. It started pretty easy with new gas though, I was surprised. I plan to run it for a few minutes before draining the fluids to get them lose. I do plan to check the valves. Break fluid is dirty so I will change and bleed. The forks feel soft, I will need to go get oil and do those as well.

    Good point on service manual, I'll pick one up. So far I have factory owners manual and that's it. Thank you

    Once I started it I only ran it for a few minutes sitting to hear it run, it felt like the head/exhaust was much warmer on the left. It seemed weird given ths short run time. After I change the fluids and actually take it outside for a short ride I'll have to check it again, so far that was the only thing that concerned me.

    I was really surprised and excited to find it too. I was telling a guy I work with about the KTM 690 SMC I just bought and he said "I've got a bike I'd sell you" when I asked what he told me BMW GSPD and I was very excited. Not telling me anything else I went to check it out the next weekend. Once I got there he told me he was the original owner and even had the deliver stamp in the owners manual.

    I was planning to buy a new GSA a couple months ago but bought the KTM instead and had been looking for a used GS etc. So this was a perfect find for me. I plan to replace the tires with something more 50/50 and yes the rubber and hoses are either hard or cracking. I can't wait to bring it up to par on maintenance and go put some miles down.

    I would not start it again until you:
    A) change the engine oil and the filter.
    B) at least LOOK at the gear oil to make sure it's not contaminated with water. You may be surprised what you find.

    That's the plan, I bought BMW engine and gear oil along with oil filter. I hope to have both changed out by lunch tomorrow.

    Well let me at least clean it up and take care of the service first...

    Oil changes require a little bit of reading up front to avoid some potentially hugely expensive pitfalls. Don't try to just figure it out as you go. Read this:

    Neutral switches SUCK!!! There, I said it..... Hopefully that thing is just dirty. I suggest removing the tank and cleaning ALL electrical connectors with some electrical cleaning spray and applying a little dielectric grease. It may sort out your other electrical problems. The neutral switch is on the bottom of the trans with 2 wires. it's a bitch to get at, needle nose pliers and a deep breath. remove wires and clean connections. Also, check the 2 fuses under the front of the tank. 7.5 amp fuses.

    Like with any used bike that sat around it's always a good idea to figure out why it sat
    then take care of those things and the stuff that goes bad from the bike sitting.

    I like to change the fluids, and on airheads I'll also pull the oil pan and clean it out, make sure the pick up screen is on and the bolts holding it in place are snug.

    When you get into the carbs pull the needles and make sure they and their jets are in good shape, if they are worn replace them. also make sure the carb diaprams are nice and soft and pliable.

    Double check the carb insulators especially from the airbox to the carbs.

    There's a number on the tire after the word DOT that's the tires age. There are online calculators that will show you when your tire was made. If it's more then 5 years old, don't put a lot of trust in it, even if it looks good and doesn't show cracks
    It should be good for the first few 1000 miles if you don't push it.

    Also check the rear wheel for sounds of bad tranny and or drive shaft. There's lots of tips on how to do that on line and in this forum.

    There's tons of information about how the circlip is going to cause your tranny to blow up and the drive shaft is ready to fail. or your oil filter canister is sinking,

    Take what you learn from internet experts with a grain of salt. Lots of them know what they are talking about.
    Some know some. and some know nothing. THe challenge of BMW ownership is figureing out who's who.

    Good luck, and enjoy.

    Nice find! There's a lot of 'Airhead talent' in the Atlanta area ... let us know if you need something ...

    Atlanta BMW on Cobb Parkway is great. Bill Kurtz there is great. The locals got some skilz too!

    But listen to diston, AW, squish ... and the rest. They'll steer you right.

    Congrats, and welcome to the asylum!!

    We all have these lists in our brains. It's good to exercise them a little. I also didn't think of bearings and it's usually the first thing I do look at.

    I just thought I would say so far it's seems a pretty complete list. There is one thing that is of the utmost importance and it's another thing that I didn't mention. See my Airhead is older. My vintage does not have this problem. It has to do with changing the engine oil and care of the engine's oiling system. Airhead Wrangler mentioned it and also gave the link to Anton's site for the run down. Post #14 in this thread. Don't miss it.

    It's called the $2,000 O-ring for a reason. If you have trouble understanding this one we'll try to give you some extra clues.

    Congratulations on a great find, Kbdakar. I just bought a '93 GSPD that looks exactly like yours. It has been ridden continuously and well cared for, so it doesn't need to be spruced up the way yours does, but I appreciate your questions nonetheless. I'll be watching this thread and hoping to learn a lot about caring for these nifty old machines. Actually, I've already learned some things here, like how to watch for correct parts when changing the oil filter. There's a vast store of wisdom here at ADV rider, and the airhead guys in particular seem very willing to help a brother out.

    Here is a thread about my first ride on the '93:

    Best of luck getting yours into proper shape! By the way, if by chance you're inclined to sell that sissy bar/backrest, please PM me. I could use something like that, as I have younger kids who want to go along with me on some adventures.
