Every now and again when I try to turn the bike on the starter sounds like it spins but like its not catching on anything. I then bump start it and it works fine.
Any Ideas?
 
Missing teeth maybe on the start drive. I think I have one for this engine, if you pull the stator cover (watch out for all that oil) and find that is the problem PM me and I can get you one. It could also be the starter, that can be yanked out the top without removing the stator cover but the carbs are in the way and so is the cam chain adjuster.
 
Hmm. I'll try and find some time. I have been feeling like a fool pushing my bike like a mad man then hopping on to bump start it down town haha.
 
Sounds more like the bendix drive in the starter.It can be redone at any starter or generator place.A bad ground could be the problem too.Check your ground first at the solinoid.Most likely it's the starter.
 
Most likley the starter clutch is worn & hangs up occasionally.

Also once it starts I can turn it off and it will turn back on no problem.

How might I go about finding the starter clutch. I am in the process of buying a repair manual.

The starter cover is right under the carbs on the left side of the bike.There is a dome shaped housing.Take it off and hit the starter and you will see the bendix drive kick in.sometimes all you have to do is clean it up and lube the shaft the starter gear slides on and it will work.It's just like a starter on your car.
 
There is no bendix on a GS starter, the starter clutch is what engages & disengages. Don't tap on the GS starter, they aren't like a Chevy. There are magnets glued to the inside of the starter case that will easily crack & come loose, if pecked on. Loose parts of magnets aren't good inside the starter.The starter clutch is mounted to the back of the alternator rotor, on the left end of the crankshaft. A tooth off the starter clutch gear may cause a problem like you are having, but I've never seen a tooth broke off of one. Repair manual or experienced help would be highly recomended for these repairs. I hope you find something easier than the starter clutch, but if the starter turns, & the engine doesn't, the starter clutch is the only thing between the starter gear & the crankshaft.
 
In light of all this I would suggest taking the stator cover off the left side of the engine and having a look inside. You'll need a gasket, or cut one from gasket paper, and the stator cover can be hard to remove because of the magnets that energize the stator.

Once inside you can see what is happening. Remove the spark plug wires so the engine does not start when testing, oil will go everywhere if it starts.

GIVE THE GUY THE CORRECT INFORMATION PLEASE.
The starter motor does not have a bendix..... The starter turns an idler gear which intern acitavates the one way starter clutch to turn the motor when the bike starts the rollers in the starter clutch retract allowing it to freewheel. It is under the left side engine cover behind the rotor. It requires a special rotor removal tool to gain access to the starter clutch. The stator cover gasket thickness IS IMPORTANT so use a simillar gasket material

If it is the starter clutch this might be a dealer repair unless you have access to a rotor puller.
 
Thanks for the advice, I'm buying the manual today finally.

Hopefully the repairs wont be too costly.

Thanks again.
 
Misimformation happens, & I'm sure it's not intentional. tconroy thought he was right, just like I thought I was right, last week, when I posted the GS series never used a hydrolic clutch. I would have bet good money I was right. After a firm repromand, I'll know from now on, at least 1 GS did use a hydrolic clutch, & I'll bet tconroy will remember about the GS starters too. As long as we're are learning here, all is OK. Just a little embarrising!!!
 
From what I remember of the GS650 starter ( I had to replace mine while I still had it) it is very much like a conventional car starter with a moving gear on the end of a shaft. Very easy to replace, I bought a used piece off ebay. You have to remember that when you have the 650G you have the oddball of the GS lineup. Very different motor, from what I remember. For example, used regular automotive style main bearings instead of the roller bearings that most GS's used.
 
Having held starters from the 650, 750 and 850 I can tell you they look the same and are almost identical.

The 650G also features a high pressure oil pump that cranks out 40-70 psi\\:D/
 
I just remember being able to replace the starter in my GS650GLZ alone, while when the sprague clutch in my new Triumph went out it was definitely a take it to the shop and have it covered under warranty type of issue.
 
I only wish they mounted it on the front of the engine like my Honda. Removing it without lifting the carbs is a tough job. The rear screw and the starter mounts are a pain to get to and if they are tight, the carbs have to be pulled so you can attack (literally) the screws
 
My thinking is it's not the starter but the starter clutch. I'd bet one or two of the three bolts are sheared off. Have you heard a "Bang" anytime you started before this problem? The stuff thereabouts can get pricey,I'd make sure I was replacing only what was broke. Hopefully our best diagnosticians will help. RJ PS If it is the starter clutch I'll give you any help I can. Mine nearly drove me to tears and it shouldn't have.:cry: #-o
 
update

update

after taking the cover of the right side of the motor I can see that the starter is turning the shaft. when I push the starter the bike will make the odd "putt" but nothing after. I now think that it might be a carb problem?

Also while investigating a sound, which to me sounds like a loose cam chain I checked the valve clearences. upon doing this it apears that none of my valves have any clearences... I have ordered a valve shim tool and intend on getting new shims...

As for the engine noise the chain appeared to be tight. someone sudgested that it might be an acct problem and since the sound comes and goes I'm guessing that's the problem there...

I also have found another issue that troubles me . haha. turning the handlebars to the right in a certain possition turns the engine off. this has made me decide to park the bike while repairs are made... as I enjoy turning right. The whole bike doesn't short out.. it just kills the engine. all my gauges are still on and such.. So I'm thinking that maybe it's the kill switch pulling apart? or maybe stripped? I have found a general area in the large mass of wiring that if i wiggle just the right way I can mimic the turning right shut off of my bike.

Anywho I should be working instead of finding things to spend money on.. like starters and wiring..

Thanks
