    I tried to start the G/S today and the starter fails to turn over the motor. also the kick starter seems to be locked up as it seems to be in a bind. also when putting the bike in gear and pulling the plugs I am unable to turn the motor by the wheel.

    Any ideas as what my problem is??

    Hopefully not a seized engine or jammed tranny. How about the starter being stuck engaged with the flywheel? If the starter jammed out, it could cause it (and the least expensive to fix).

    Good luck

    good point. most simple thing to check is the starter. pull the seat and the tank. take a 5mm allens and pull the starter cover. I can't remember if you can actually see where it engages. If not, you may just want to pull the starter altogether--still not a big job.

    To find out if it's the engine or the gearbox. pull the gearbox back like you were doing a spline lube--enough so that the splines are out of the clutch. try to spin the gearbox with the kickstart and try to spin the engine using a 6mm allens in the nose of the crank behind the alternator cover.

    I'm eager to find out what's the dealieyo.

    Just pull in the clutch lever to determine if it's the trans or the engine. no need to pull the box.

    oh yeah....the clutch.......to be fair, I've pulled my gearbox so many times I don't even think about it. Kinda like getting on the highway that you take to work but you're actually going someplace else--if you're not paying attention you end up in the parking lot at your job wondering how you got there.

    An excerpt from my R90 thread, when I got the bike: "I hooked it up to a battery charger, and got the starter button to work finally. But, I heard crackcrackcrackcrackcrack when I press it. Hmm.. did it seize up? I am pretty sure I could turn 'er over with the kick start. So, I try the kick start. It's not going ANYWHERE. Damn it. So, I pull the clutch and try the starter button. Now it's just bogging down instead of crackalacking. It's still not turning over. So, I pull the clutch and the kickstarter can swing down now, too.. but that doesn't turn it over, and there's little-to-no recoil. Damn."

    My engine was seized and I had transmission issues. :lol3

    I doubt your problem is anywhere near as severe... unless you've left your bike in the elements for 25 years, too.

    I think a little more history is in order here, like what happened since the last time it ran? Has it been sitting for three years outside with the carbs off, or is this something new since it was ridden last weekend? Were there any weird noises or indication something was wrong last time it was running?

    It's highly unlikely the trans or final drive are locked up, but possible. Also, the G/S having nikasil cylinders isn't prone to the rings rusting to the bore. Perhaps the brake shoes have bonded to the drum? Sometimes one of the U-Joint bolts will work loose and jam the driveshaft.

    So what happens when the motor is cranked with clutch in? I don't believe the kickstart will turn over the motor with the clutch in, but if the kicker works, that would tell you the trans is free. You can also pull the rear wheel through a rotation with the trans in neutral, and would tell you if the trans and FD are ok.

    I checked the starter and it appears fine, took it loose from the flywheel and checked that the starter worked freely. It did.

    Does it look like anything is missing here??? Reason for this question will be evident later!!

    With the starter off the kick starter still wouldn't turn the motor over??? So I pull the tranny...and this is what I found....Look at the metal at the bottom of the picture. Is this part of the clutch or maybe something off the starter?? I was able to turn the motor from the flywheel side, but I did feel some metal binding a little. After a few turns the metal flakes freed themselves. Where could this metal come from. A good thing is that the tranny turns over freely w/ the kick start and at the input and output shafts. I'll pull the clutch and maybe see something.

    The only symptom I had was that the starter was getting slow to engage when pushing the starter button. Actually not slow it just didn't do anything and after pushing the button a few times it would work.

    Are all the teeth on the starter present? From your pic you can only see a few of them. That would be a bit obvious I guess.

    Yes all the teeth to the starter are present.

    This is what the remains of the metal look like, I just don't know what it's off of???????

    Yes it is from the Bendix, available from motor bins for $25 vs 102 in the states, I wonder if a rebuilder can put it on for me, better than what a complete unit would be. Just got to figure out how to get the old one off the ammeture.

    Looks like a flat washer.

    It looks like the back side of the bendix gear, in the picture of the starter previously, the bendix appears to be in the out/engaged position. it's not supposed to when not working.
    if that picture of the washer like thing is what I think it is, the starter bendix has committed suicide.

    See post #12, part of #3 in your diagram. I'm going to order a new bendix, brushes, and parts kit from Motorbins, and fix it my self.

    You have a Bosch, and that diagram is for a Valeo.

    Anton: Yes. I posted the picture for my 93 GS that has a Valeo I imagine. He didn't state what year his G/S was but it should look like this then?

    Would it be part #19?

    Yeah , I new it was a Bosch. at least it's not the tranny. I've wondered about the circlip, but figured w/ 95,000 miles either it was already replaced or isn't something I need to worry about.

    Just wonder how long it will take to get the parts from England. I could have just ordered starter parts, but when checking the clutch, it was measured 0.110" min thickness is 0.1722". It shifted rather well w/ a worn out clutch. Will be saving a ton of $$$ instead of ordering in the states.

    :amazonI mentioned G (slash) S, i.e. G/S, there is a difference.

    So , I just gotta ask....
    Did you even attempt to price that pinion here in the USA?
    $56.00 is not a lot of money. How much is it at Motobins with shipping and possible VAT.?
    I think that everyone assumes that ALL parts are out of this world expensive here in the USA. Some are, some are not.
    But $56.00??
    Come on lets stimulate our economy a little.
