The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Well, that was weird...

Didn't know exactly where to post this so here goes. I finally got the big 1000G legal yesterday and decided to tool on down the highway a bit. Decided to head out to Competition Accessories and poke around. Got some really nice complements from a couple sales guys there who remember the old bikes fondly. Anyway, more to the point, As I was heading back across I-70, all of a sudden, the bike went completely dead. Nothing. So, I pulled over to the shoulder and stopped. Tried to start it back up right away and it acted like it wanted to start, but wouldn't. So, I got off and started looking it over trying to find some indication of something wrong, but nothing appeared to be wrong. After several minutes, I decided to try starting it again and this time it started up. Ran fine the rest of the way home. I hate things like that...not knowing what happened. :mad: So, at this point, I'm feeling somewhat distrustful of the old girl. Anybody have any ideas?? :confused:
 
My first guess would be something electrical - R/R, dirty connectors, fuse block, etc.
 
check all your electrical. even in the headlight bucket. Mine was sporatic like that and it was the plug in the headlight bucket.
 
My honda 650 had a vacuum valve on the fuel line, the little hose from the carb to open it had a too tight loop once and when it get hot it got close so the valve stop the fuel. It took me sometime to figured that one out. The bike stop when hot and start again after few minutes. It maybe electrical also, check connections at kill switch,ignition, coils etc.

Good luck.
 
Replace all your glass fuses & clean up the fuse box. You can have a bad one that looks good. Also check the connections on the kill switch & ignition key switch.

I would also check the coil connections & ignitor connections too..

I am distrustful of Suzuki Ignitors after 30 years at the best of times & for ultimate reliability would switch one out to a Dyna S.
 
Definitely go through your fuse block. Mine did that and that's all it was.
 
maybe a fuel supply problem..
it tried to start..let it sit for several minutes then it fired up and ran fine.
dunt know but maybe.
 
Although your bike is a 10 cosmetically, it sounds like the PO was negligent on the maintenance and/or the bike sat for a very long time (judging from all the grief you had with the carbs).

If I were you, I would start in the headlight bucket and work my way to the taillight cleaning every connection. It will probably take you half a day but it will be well worth it. Deoxit is an excellent product for this, they sell both a cleaner and a protectant.

Well, I did most of that when I first got the bike, but there's probably some areas I missed. You are correct in that it sat for a long time. Can't believe it's a fuel supply problem considering all the effort and time put into getting the carbs back in shape. In fact, I don't believe that at all. Anyway, I'll start with electrical cleaning.
 
Pop your fuel cap off once and see if your tank is rusted internally. Mine did the same thing once. Im cleaning my tank now.
 
Check the power feed going into the connector on your fuse block. Neglect of an overcharging system will melt and or loosen the pins in the connector and cause it to cut out intermitantly. Had that happen on my ES right in the midst of being heeled over hard in a turn. Was a puckering moment.

No problems there. I'm sure if there were, Steve would have caught it today as he was looking the thing over.

On a side note, man I'm sorry to hear about you and Rose going down over in Indiana. Sure hope you two are physically ok. Hope the ES isn't too trashed either. Gravel SUCKS!
 
+1 on checking the connections in your headlight bucket. Mine did exactly the same thing, found burnt connections in the bucket.

Possibly, but I did not open the tank. :o

Al, I'm going to have to respectfully disagree with you on that one. :p

I saw the bike today, it's at least an 11 or a 12. :clap: :D

The only real fault I could find was some REALLY OLD tires (won't mention the date code, but they were REALLY OLD).

On the plus side, a previous owner had installed a relay to cut out the headlight when the starter button was pushed. :clap:

I don't know which petcock the 1000 has, but the GS850 has a vacuum petcock, and the diaphragm is rubber, subject the the same ageing process as the rest of the bike.

I had a problem with mine, the diaphragm would permit the carb bowls to fill, but on a longish run would not replenish the bowls. The bike would die very quickly due to fuel starvation, but would start again after sitting for a few minutes. The alternative was to disconnect the vacuum tube from the carbs and sucking hard (strictly a get-you-home trick) to refill the carb bowls.

Solution - new diaphragm / petcock.

That's an interesting thought. And I remember another thread about this recently. I wonder if that could also be heat related because on my 1+ hour ride yesterday with no problems, it was a lot cooler than the other day. hmmm
 
My 80 GS450L pulled that on my once. I guessed the petcock stuck closed. Flipped to "prime" for 5 seconds and in a couple of cranks it fired. I think it just stuck closed because it had been sitting. Around that same time I got a little fuel overflow meaning it stuck open. Neither has happened again since a few tanks of clean gas with a bit of Sea Foam.
 
Your carb vent hoses are not too long are they? If they're too long fuel won't flow to the carbs properly on an extended long run. I think they should stop just below the airbox.

I had that problem on my 850 before.
