Hi Guys, new owner of a Gs650G 1983 here, I have a problem with the battery, in the first start the battery drains, so if I didn't manage to start the bike on the first attempt the battery is dead, I already change the battery for a new one, and already check that is charging. I have now idea what to check now, I will appreciate any suggestions. Thank you all in advance.

Well, your 650 should start in less than a second, so you may have a number of problems.
You say you checked your battery, what were the numbers?1978 GS 1000 (since new)
1979 GS 1000 (The Fridge, superbike replica project)
1978 GS 1000 (parts)
1981 GS 850 (anyone want a project?)
1981 GPZ 550 (backroad screamer)
1970 450 Mk IIID (THUMP!)
2007 DRz 400S
1999 ATK 490ES
1994 DR 350SES -
Do the quick test and post the numbers. How did you determine that the battery is being charged? Quick test and other useful links for you are in my signature.Links

New to you?? .....understand how the ?choke? system works ....it?s actually an enricher device.. it?s supplies an extra dose of fuel into carbs throats. But you must not apply any throttle when you use ?choke? during cranking or you defeat this cold start method and bike will just crank away! So apply full ?choke?, no throttle twisting,and then crank.1981 gs650L

I would look very closely at the starter motor. Take it out, inspect and clean it or repair it.
Do Test it on the bench while it's out of the bike to be sure you have fixed.
It's the only thing I can think of that would drain a good battery so quickly unless your Positive battery cable is intermittentently shorting to the frame. Because, there is no fuse between the starter motor and the battery. Any other electrical fault would blow a fuse before the battery was killed.Comment

Just wondering how long it cranks until the batt. goes down?1983 GS1100E, 1983 CB1100F, 1991 GSX1100G, 1996 Kaw. ZL600 Eliminator, 1999 Bandit 1200S, 2005 Bandit 1200S, 2000 Kaw. ZRX 1100Comment

Rphillips, I'm assuming it dies almost immediately from original post, but yes-"how long is it cranking?" is a question. It might be turning steadily for minutes for all I know!in the first start the battery drains, so if I didn't manage to start the bike on the first attempt the battery is dead,Comment

Yep, just wondering. 5 seconds of cranking should easily have it going, but if the batt. is dead after only 5 seconds??? Something ain't right.1983 GS1100E, 1983 CB1100F, 1991 GSX1100G, 1996 Kaw. ZL600 Eliminator, 1999 Bandit 1200S, 2005 Bandit 1200S, 2000 Kaw. ZRX 1100Comment

Hi Guys I have some progress, so I found some ground connections lose, after changing the tipa y reconnect everything I don?t have the problem any more, so the bike try?s to start and don?t ?kill? the battery trying 😄, but now the bikes try?s very hard to start even with the choke press on full, now it?s a totally different problem but you have any ideas ??
thanks all for your help and interest in my problem, very happy to found this great forum!Comment

Your ?choke? system probably is clogged....not delivering extra shot of fuel into carb throats. If you drop a fuel bowl ,you will see a small tube that protrudes out of carb body....this tube gets fed by a small hole in bottom of fuel bowl. Both the tube and the hole are easily clogged preventing the ?choke? system from allowing fuel to reach carb throats.1981 gs650L

Now you are back to it could be any number of problems. Adjust the valves, overhaul the carbs and replace all the O rings first. If there is still a problem, it will be a lot easier to track down.Comment
