78 gs1000e keeps dying

[Guest]

hi everyone I'm new to this site and I'm new to the gs1000, I purchased one in September after looking for a bike I want to restore its in pretty good condition and starts fine but after its running for 5 to 10 minutes to dies and then when I start it again it starts but dies nearly straight away could it be its not holding charge I have clean and check connectors to regulator/rectifier and the earths and it go a new battery fully charged, would it be worth testing them with a multimeter or am'i on the wrong path, thanks any help would be great.

Does it have spark? Does it have fuel getting to the engine? Compression?

sounds like fuel starvation, have you tried running it with the petcock on prime?
check the fuel line and vacuum line from tank to carbs also the vent in the filler cap to see if that is blocked.
if all ok so far it sounds like you need to strip and clean your carbs thoroughly and check all settings, especially float heights.

Very likely that this bike has multiple issues- so rule them out one by one!
Folks here like pictures, so offer some

Welcome to the site. Everybody else above has put you on the right track and so I will only address this one part - it's always a good idea to use the multimeter to ensure your electrical system is working properly. Using the top ten newbie thread that Nessism pointed out, go through and check everything.

thanks for the replies guys yes the bike has a good spark, I will check the fuel line and vacuum line and also the filler cap breather also, do you boys think I should start from here and see how I get on, I will also check the links you have posted me can't wait to get stuck into this bike

just went out to bike put tap on prime and away she goes she ticking over lovely now for 10 minutes not a problem, so people what's the problem here is it the petcock?

[tkent02]

Maybe you are low on gas? On only goes to about two ir three inches left in the tank, PRI and RES go to the bottom.
Maybe the normal petcock screen is clogged, PRI or RES uses a different screen.
Maybe the vacuum operated petcock isn't getting enough vacuum to turn it on completely?
Could be a few other things. At least you have it narrowed down now.

Start by filling the tank, and then testing the petcock.

Don't let it idle too long, parts of the engine will get very hot without airflow.

[dartfuldodgers]

I will try what you said first, fill tank and try petcock turned to on, if still having problems maybe screens blocked restricting flow is this what you mean? I'm made up I've progressed already and I've only started on site today!

[tkent02]

Don't fill it too full, if you do need to remove the petcock you will need to put all that fuel someplace.

yeh true didn't think of that haha, since I'm new to the gs1000 is there anything you recommend to me to do to bike to keep it in good working order, I love working on bikes and eager to learn as much as I can.

Dont worry about filling it up. All you need is an empty 5 gallon can and a good length of hose. Run it from the big nipple on the petcock to the can and set it to PRIme..let the tank empty.

I also advise you rinse the tank with some gas and drain it off thru an old sock or something that will catch the sediment that comes out..this will give you an indication of what is laying in there.

To rinse the crud out of the tank youll want to flush it several times and drain it till you no longer are getting crud in the stariner material.

if your just running it sitting still...PUT A FAN on the engine..or one on each side.

Once youve sorted the petcock, then youll need to do the valves, rebuild the carbs, and sync the carbs with the proper guages.


If a lot of rust comes out when you filter the gas to see whats in it, youll also want to derust and line the tank.
