Suzuki Bandit running problem, can someone help?
Im having a problem with my bike so ill list all the infor
2001 Suzuki Bandit 600
4 cylinder, 4 carburator
Just changed the spark plugs
I was going to ride to work and after about a mile of riding i noticed my RPMs were falling. At a stoplight it seemed like the bike was going to stall, I had to hold the revs up to keep it from stalling. I pulled over to the side to play with it and when i let go of the gas the bike stalled. I tried restarting, no luck. I tried playing with stuff, no luck. I ended up waiting about 5-10 minutes calling insurance to get it towed. I tried starting up my bike and it ran fine! I drove a little less than a mile and started having the problem again, so i puleld over and same problem. I decided to drive it home, and waited 10 minutes and it started again. Sure enough the problem came back so i just held the throttle so it wouldnt die till I got home. Even then soemtimes it wasnt responsive to gas while accelerating from a slow speed.
I jsut had the bike for a regular service, so i would expect them to have found something obvious wrong.
I had had problems before i got it serviced that i think stemmed from having the bike sit for 2 months while not being driven. The people at the service station didnt report anything.
There is enough oil.
The battery turns over just fine, doesnt seem electrical.
Ill list the other things ive tried
Tried running it with the gas cap open to see if there was a vacume problem, but it didnt help.
Added seafoam to the gas, no help.
The petcock didnt seem dirty at all
I did a number of things today.
I checked the air filter, clean
Then i pulled out the carburetors and i opened up the top and bottom, checking the float, the little plunger attached to the float, that long needle that is attached to the diaphram on the top. I didnt pull out all the screws, i just puleld out the mainjet and inspected them. Clean. The other recessed small one i didnt have a screwdriver that would fit. Well one was too skiny and wouldnt turn the screw well.
The insides all appeared clean, couldnt find any gunk/residue/slime/anything. I put it all back together put the tank back on, started it up and let it run. The motor sounded slightly different. Maybe a little bit rougher but nothing bad. Sure enough the problem surfaced after a few minutes of being on.
I checked the spark plugs, slightly black but im guessing thats normal?
Important thing i found. As i was reading through my manual for any other ideas i saw a picture of a hose I had always wondered about. The picture said it was a drain hose and you remove the plug to let any water drain out. This hose comes from the air box. The section was talking about air filter cleaning. So i figured what the heck, ill go open it.
So i find it and open it and this liquid comes out pretty fast. I plug it back up and get a cup to catch it. I let it drain and i would say all in all abou 3/4 of a cup of this liquid came out. It is amber in color, smells a little bit like fuel but not completely, is to viscious to be oil or transmission fluid. Dirty liquid i think, had a small amount of sand like stuff inside too. Maybe a mixture of water and gasoline? It doesnt seem to evaporate real fast either, there is still some residue on the ground. I clean some of it off the ground with a paper towel, then to figure out what the liquid is i folded up the paper towel and lit it on fire. It caught fire taking about 5-10 seconds before the fire spread to the whole paper towel. It gave off a black smoke, and i had to stamp it out.
Gasoline would burn faster wouldn it?
So not sure what the fluid is but im hoping that was somehow the cause of my problems. Ill go start the bike and see what i can find...
EDIT:
I turned the bike on and let it run. After a few minutes the problem resurfaced. Surely that liquid isnt supposed to be there but i thought draining it would have solved my problem... darn...
Help is much appreciated.
