The other end of the small vaccuum line that comes from my tank isn't connected to anything, where does it go, if anywhere? My bike isn't starting and I'm pretty sure this is why, even though it ran fine last time. When I had to reattach my throttle stop and put the tank back on I left it hangning because thats how I thought it was before, and it started and ran fine, I drove it and was all good. But now I can't get it started at all.
Basically my bike was running fine a few days ago then it sat for a few days, now I went to start it and it keeps turning over but wont start, just get a big backfire sometimes. After turning it over so much my battery is dead now, so I was jumping it, still won't start when jumping. Seems like its just not getting any gas or something, not really sure. It's a 98 F3

unless you bike is a cali model the 2 small lines off the fuel tank are just a vent line and a over fill drain line, then the big line is of coarse the fuel line, no vacuum to any of them,, i think (NOT SURE) that the cali models have a canister with charcoal in them that the fuel tank vent line goes to for environmental reason but even this should not prevent your bike from starting, might keep you from passing emissions test though,
i would check the fuses first then for spark and fuel, switch your tank to reserve i have parked my bike a couple times just as it ran out of fuel and when i tried to restart it would do the same thing, god i felt dumb as sh*t both times lmao

Thanks for replying, the fuses are all good and the tank is full..I put a half-can of carb/feul system cleaner in about a week ago, like seafoam but its called Berryman's b-12 or something like that. Also put in some fresh gas with it since the bike was sitting a while and was running a little rough.
The thing is I only drove it a few miles after that, so I think maybe the cleaner freed up some gunk and now its all clogged up, maybe I should have kept it running longer I dunno..not sure if I'm up for taking the carbs out and apart to clean them, plus my batt is dead too so kinda stuck now

i could see the cleaner maybe clogging up one or 2 of your carbs, but to kill all four i would not think so?? i would check for spark and pull the spark plugs to see if they are fouled and not firing hot enough, if that checks out i would undo the "out" side of the fuel pump and make sure its pumping fuel, if neither of those fix it then i would clean the carbs
Edit in::: i just noticed you put in half a can of the b-12 cleaner it may have been to much and made the fuel harder to ignite, which maybe your cold start problem check spark and fuel pump first if they check out drain the fuel down to reserve while you have the fuel line off the pump and add fresh 87 oct fuel, if after getting fresh fuel to the carbs it still won't hit then i would tear them down, do a search on here there is a thread how to rebuild your carbs ... i maybe wrong about the cleaner but that seems a bit excessive i think that amount would treat 8- 10 gallons i think?

Cool thanks I will try that out tomorrow maybe you're right. I was going to get Seafoam but they didn't have any. I had read a post by someone that had a rough running engine and said they added half a can of Seafoam and it worked great, so I added half a can too. But you're right the can says 1oz per gallon I think, and I must have added like 7 or 8, guess I went a bit overboard...so yeah I will change out the gas, if its something as simple as that I'll be one happy rider haha
edit: also, the gas I put in was 91 octane but it was only half the tank about 2 gallons, there was half a tank in there already when I got the bike but I don't know what octane it was, I went with 91 since thats what the manual says

I'm not for sure if it would make it hard to start cold or not, but something you might be able to try is some starting fluid to get it to hit thats how we use to start or alcohol dragster until the engine got warmed up to run on just alcohol,

One quick question, I'm draining the gas out now and noticed another small tube coming down from the feul pump, is it just a drain or should it go somewhere?
edit: here's the tube I'm talking about:

that tube does not go to anything it just hangs there,
did you pull the spark plugs and test for spark?
try this post on how to clean the carbs, if you have some simple tools and some basic skills you can clean them your self :) http://www.cbrforum.com/m_311016/tm.htm

Oh alright..I didn't pull the plugs I don't think I have the right long sprockets to get in there what kind/size do i need... Someone told me to drain the carbs too...got the drains loosened and its dripping out, except for #2 which I can't reach.
I went out and got a trickle charger and have it charging now...I have had that cleaning guide bookmarked for a while in case I ever had to do it, seems easy but I don't know about getting the carbs off and back on again with all the hoses and what not, and dont want to go through all that, get it back together and still have the same problem
edit: drained the carbs and this is what came out, its all clear with pools of this brown stuff in it, wtf...

looks like you have found your problem the carbs are full of water, pick up a bottle of fuel dryer / water remover to add to your fuel tank to help get rid of it

O and also you will need to most likely pull the sparks plugs for sure now and let them dry out along with the cylinder's

full of water, damn how could that have happened? I've never had it outside while raining at all or anything like that, and was running good just last week when I rode it, was only a couple miles though and I haven't had the bike too long. Beore that it was a little rough but still started and ran. Is it possible there was gas in the tank but water in the reserve when I bought it? Or someone put water in my tank somehow? I've heard water ruins the engine I guess its a good thing I drained the tank. Thanks for all your help man really appreciate it. Is it possible this caused any other damage I should worry about too
So when I get this stuff just throw it in the tank w/ the gas, and try to start so it goes through and dries it all out? I guess I better drain out that #2 bowl too I just need a longer screwdriver

i would switch the tank to reserve and pull the line off the bottom of the tank to drain any water that may still be in the tank, then drain all the carbs, at that point i would hook the lines back up and put some fresh fuel with the dryer in it into the tank, and let the bowls fill back up with fuel and then drain the carbs one more time to make sure all the water is out, just the carbs not the tank, if that dirt cam out of the bowls then you may still have to clean the carbs but at this point it should atleast hit, as for damage its hard to say i would guess since it was running there wouldn't be any damage, the reserve on the fuel tank is just a lower tube on the fuel valve not a separate tank, just one tank with a high tube which is the "on" when the fuel runs out at the high tube you turn the valve to reserve and it then pics the fuel up at a lower point in the tank, just for reference water will sink to the bottom of the tank so you would get water before fuel because fuel is lighter than water,
as for how that much water got in the carbs i would guess that if you switched to reserve the water filled the bowl due to the fuel floating on top of the water, or if you used a gas can to add fuel it may have had something in it
either way once you get gas to the carbs and dry out the spark plugs it should hit and run, still doesn't mean you wont have to rebuild your carbs though, best of luck with it

ok great, thanks again I'll flush a couple times and see what happens
edit- Alright I got the longer screwdriver for #2, and a spark plug socket..while #2 was draining I pulled the plugs out and they had a black coating on them, so I cleaned them off with a little of the cleaner and they looked alright so put them back in, added a little cleaner to the gas, tried to start, no go. Should I just go get new plugs?
Until then I'll drain the carbs again like you said once or twice more and try it again, if still nothing I guess I'll grab some new plugs
