I didnt take out my spark plugs. I dont know whats up with the hose thing. Its strange the way the hoses go all over the place, some just stop left open, others conect to things i wouldnt think they would conect to. The bike hasnt really changed the way it was running since i hooked everything back up so i must have hooked it up correctly. Ill probably ttake it to the shop this week, I have tried just about everyones suggestions that are within my ability.

Important update
Important update.
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...

Black means it's running rich. Plugs should generally be a chocolatey brown in color.
Without seeing diagrams and the actual locations of hoses, etc, it would be hard for me to say whether this is normal or not. And why it would light on fire it beyond me... Especially if it's to the air box and a drain hose. I would say that if there is gas in your air box, and your plugs are black, then you definitely running really rich. That could be a stuck choke plunger, or one that is leaking.

Could it be that as the engine heats up it messes with a choke plunger? Do choke plungers get dirty, gotta take em out and clean them?thespirit wrote:Black means it's running rich. Plugs should generally be a chocolatey brown in color.

I don't think it would be a situation where the plunger would get hot. They should be far enough away from the engine to not get that hot. However, anything is possible. The more likely scenario is that with the plunger stuck open slightly, it could start to slowly flood the engine out. You can take them out and clean them. When you get them cleaned and back into the carbs, make sure you work the choke lever really good and make sure they are sitting all the way back down when you turn the choke off. Push on them with your finger to make sure.eyeeatingfish wrote:Could it be that as the engine heats up it messes with a choke plunger? Do choke plungers get dirty, gotta take em out and clean them?

I read the manual but adjusting the float heights seems a little confusing to me.
I have some other updates too.
Update.
Checked the spark plugs again at the advice of a NAPA dude. He said sometimes they might put in the wrong spark plug, there is standard, cold and hot. He said older bikes might need hot, so i checked the manual.
Standard: CR9EK Cold:CR10EK Hot: CR8EK
I pulled out a spark plug and it was labeled CR10EK. Hawaii doesnt usually get cold. Also the plug head was indead black and when i wiped it with a paper towel black stuff (carbon?) would wipe off, kind of powdery. It had a slight smell, possibly fuel.
I checked the drain hose comming from the air box and to my surprise, it dumped out a cup or so of liquid. Will fuel mix with oil to make an amber colored liquid that is thin like fuel but leaves a residue like oil? There are only 2 tubes that run into the air box, one comes from a device that splits into 4 tubes that connect to the engine just below the ehaust pipes. Im guessing this provides suction or pressure? The other tube comes from a block like shape that is part of the head of the motor. Is this an oil overflow or something?
I pulled off the tank and had it running, I sprayed some starter fluid into the intake when it was starting to run a little low on the RPMs, didnt seem to change anything. So i pulled off the filter and tried to start the bike but couldnt get it to stay running and spray it in the box at the same time. So i sprayed a half second spray into the air box then tried to start it but it didnt seem to change anything. Maybe im doing something wrong here or is this pretty simple?
One other thing I did do was i decided to drain some oil. I set it up to drain slowly until i saw the line come down. Well i filled about 2 cups worth of oil, and dropped the plug and spilled a bit more oil DOH! I plugged it back up and got the bike to run. It ran for a few minutes and the problem surfaced and the engine died. The bike straight upright on the rear stand. I looked at the window and it was still above the full window. When i put the bike on its kickstand i noticed the fuel was just about the F line. I guess this could be two things, either the oil isnt circulating or there was way too much. I watched the window as it was running and saw the oil churning and whatnot so the oil seems to be moving about, so im guessing the oil is circulating.
The engine didnt seem unusally warm after the time it was running.
I checked the air box drain hose one more time and found that it hadnt filled up while working on it/running it.
I havent checked the battery, but i dont have toold to check electrical stuff.
Im starting to wonder if the shop messed something up on the bike. I know they put the flanges that connect the exhaust to the engine on backward.
Thanks for all the ehlp and patience so far.

To check the engine oil, you should do it after the bike hasn't run for a little bit. When was the last time you (or someone else) has had the oil changed on it? If it's been a while, you might want to do a full change including the filter. This will make sure that you have the proper amount in it.
I am not 100% sure what the hoses connecting to under the exhaust pipes would be, but the one going to the head is going to be a breather hose. The ones for the exhaust could be emissions hoses that work much like the breather hose does. It will put crankcase vapors back into the air intake for reburning in the engine. It helps to eliminate harmful engine emissions by reburning them in the engine.
I wouldn't think there would be a large amount of fluid coming out of these. Have you done a compression check on the engine?
