Thanks for the reply. I am not sure which bolt to loosen to check fuel. Where is the carb bowl? It is hard reading that carb diagram.

here is what your carbs looks like.

the bowl is the lower part, it has a purge bolt on the bottom, on each and every one of your 4 carbs, unbolt it a bit and you ll see if you have fuel in there, check the color too, red is bad.

do not forget a rag!

but you say you smell gas, i am pretty sure that your engine sees the gaz coming in,
do you see any on the ground?

would be cool if somebody with more experience could give a list of things to look for in order but well,

you need fire, air and fuel for it to start up.

check the carburetor bowl to see if fuels gets in there.
maybe you could take out a sparkplug, connect it on its wire and check if you get a spark when cranking the engine. (keep away from inflammable stuff please)
about the air filter, i have no idea if cleaning it with water is that bad, but i guess it s not perfect.

lower end of the diagram, the bowl is part 1 on the diagram.
the bolt you want to loosen is the bottom one, it s the only bolt on the bottom anyway, you won t screw up anything by unbolting it :)

see the image there, even if your carbs might defer a bit, the lower/bottom bolts? these one :), the bottom parts are the said bowls.

catch the fuel in a recipient though.
 
Uhm. Did you wring the filter you submerged in water out? Is it dry?

Before you do anything. At all. I highly suggest you find and download a shop manual for your bike.
Being that you're not all that mechanically inclined, and this is your first bike, I wouldn't suggest touching anything just haphazardly. It is very easy to screw something up without direction or guidance and the bike may never run again. Without a manual and a basic knowledge of mechanics, reading here alone isn't a good idea...
 
True. My buddy knows some about carbs. He only has one on his dual sport.

I'm new to all this stuff, but it's interesting:)

I live in Cincinnati

Somebody needs to come over and show you a few things about your bike. :o

Yeah, I made sure it was dry before putting it back in.

I have a pdf of a shop manual I got from the web. I also have a physical copy on order from amazon.

I am not trying to mess with to much stuff, as I said it worked fine all day today and after I sprayed the chain it would not start...

I would love for someone to come over and show me how all this carb stuff works, haha.

i agree with you, a manual is absolutely vital, that being said the manual won t help him troubleshoot the problem that much.

he needs the manual combined with help from people like you with a lot of experience to find the solution.

as long as he doesn't go crazy and start unbolt the whole engine out i do not see what could break the bike down to a ''never running ever again'' state, by doing a basic list of checkups i mean, fuel/spark/compression. yes?

i mean it s no mystical science, even if it tends to be scary when you first start learning all that :eek:

got to jump into it to learn, :D
 
Exactly. I am trying to learn the basics of troubleshooting problems. Plugs,fuel, etc.

Like I said I have only added premium fuel with seafoam, and cleaned the air filter since I got it. Which was yesterday.

Then all of a sudden tonight, it will not start.

i d say check in your pdf manual, read a bit through it first anyway.
not just the owner one by the way, the service manual of course :)

look at Mr Bass Cliff 's website!
you ll find a lot of things on that awesome website
http://members.dslextreme.com/users/bikecliff/

you should be able to find the location of your fuse box by yourself,
that would be a good exercise/start ;)

pop your seat open!

do you have any electrical knowledge by the way?
 
I appreciate everyone's help with my problem. I will check my fuses later this morning, as for now I am heading to bed.

Thanks again!

Jason
 
the fuse box is behind the right side cover the choke is situated on the left hand side of the handle bars.you have the turn signal switch below that the horn and below that the choke lever.if you have no choke cable and suspect the choke is on look at the carbs from the left side, if the choke is on the choke rail should be poking out just below and in front of the the square top of the first carb push the rail in and the choke is off. cheers hope that helps

I just bought the bike yesterday and rode it for an hour or so.

Oil level is good. I added 2.3 gallons of best grade gasoline and a couple ounces of SeaFoam this afternoon.

Not sure if this is the cause or not. It smells like gas heavy in my garage. I don't see fuel leaking anywhere. I am not very mechanically inclined, and this is my first bike.

Cheers for any suggestions.

The motorbike is a 1981 GS650E.

After putting gas in this new to you bike and enjoying a ride, I'd suspect petcock failure since you smell gas in garage- likely in crankcase oil also. Recheck oil level- has it gone up, does it smell like gas?? Choke lever came stock in between bar clamp bolts but someone could have substituted a left handlebar switch with choke there. Sort things out, before you go leaping to pulling stuff off. Having the bike run for an hour is a good sign- even it starts right up today, I'd do alot of checking before I'd run it much again- you never know what the PO has done (or not done).
 
If you have been trying to start your bike a lot your battery may be run down.You will need a charged battery to attempt more starts.
