Anyone had this??
The GS won't turn over freely on cold start. Is almost as if the battery is dying, but the battery is new and fully charged. Once started, the bike will run well and re-start fine.
It bumps starts ok and runs ok.
Anyone else had anything similar???
Had a similar thing on the cb, the culprit was a fried reg/rec over charging the battery. The voltage across the battery was fine when the bike wasn't on, seemed perfectly healthy but it was slowly burning outQuote:

Does it make an attempt to turn over or just do nothing?!
It turns over very slowly.
Could be carbon brushes in the starter motor i suppose, like a washing machine they go with time. Easier to get a secondhand motor off Ebay than replace them.
Does the gs have a bendix drive? The one on my RS was a constant cause of starting issues
No, uses a sprag clutch.
mine had this a while back......it was fuel, as it was on a paddock stand the fuel had moved away from the pump, took a fair bit of shaking the tank to sort back to the pump. Fuel filter ok?
It fires up fine. The issue is the slow cranking.
I think it may be a dodgy starter switch. Put a battery cut off in parallel and turned over fine this morning... will see again later.
Jon I had a similar issue with my old GS, it was -12 outside though.
Battery took forever to fire the engine into life, is the bike kept outside overnight? I know this can affect the battery on these quite badly, when mine was garaged there was no issue but a couple of nights out in the cold and it didn't want to know.
Mine was the battery dying even though it was 2 months old, dealer replaced it FOC but yours might be a different issue.
sounds more like a tired starter to me, once fired the tolerances are greater, as outer casings and bushes are warm, take it of clean it up and oil it up, worse case its time lost best you may fix it :) not too difficult to strip, will allow you to clean the main contacts too, try shorting the solenoid when cold to eliminate the start button.
Cheers guys. That's very interesting Dan. Mine's kept in a garage... the minus 12 I remember.... I was using two batteries to crank the mini over then. The oil was freezing up in the sump!!!! (I know coz I left a sample of oil outside - went to look the next day and it was treacle)
I'm coming to a similar conclusion Gooz. I've jury rigged a manual starter relay in order to eliminate the relay as the issue. Will see how it goes. If it still playes up I'm gonna have to try to strip the motor or buy another....
Likey this!!!

I'm thinking tired starter... :(
Now it's totaly feking died....
The starter is rotating but not the engine. Ar5e!!!
This is apparently common on GS500's.
Alternator has come adrift!!!!! :o
AR5E!!!!
ouch hopefully not taking any casing etc with it ??? last thing you want is a full strip down to find filings :(
Luckily it stayed on the crankshaft. However it's knarled the taper it sits on so that'll have to be dressed in both parts before refitting.
Ah yes. Sorry mate, but it happened to one of ours a while back. Your explanation of the symptoms should have rung a bell. We had the bolt that holds the alternator on, come adrift. Started with 'slow starting' issue, then became a 'starter not engaging' issue. Chewed up the end of the crank, but was just about salvageable. If it's properly chewed, you maybe looking at a new crank (or secondhand engine). It's only happened with these Spanish-made piece-of-crap Suzuki's. Jap-built bikes had no such problem. Hope it's all ok, and repairable... :-/
Repaired. Was pretty chewed. If it dies it again it's the perminant loctite for the shaft!!!
