Warning-long story-
I have to start in saying that this site is a life saver. I looked for days and couldn't figure out how there was not a Katana forum. I recently sold my 1997 Prelude SH. I sold it stock, and with the money from parting it out I bought a 1993 Katana 600 from my friends older brother. He said he rode it once in the last year and a half (said he used fuel stabilizer), and I got it for a gooood price.
So I had a friend ride it home, where it ran good. We rode the next day probably 100miles, ran like a dream. Then later that night, I took a girl/friend for a ride and it died after the ride in the drive way. (I played it off). It started later that night and I rode it to play poker about 1/2 mile away.
The next day, I started having problems. Basically it wouldn't start w/o the choke on, and then died at idle often, like at a stoplight while test riding. (pilot jet I have read about?)
So I take the carbs apart (my first carb work, all my cars were fuel injected), and they are DIRTY AS HELL. Rusty brown colored gunk everywhere, and when I drained the gas from the little drain screw, it was like someone mixed every color of Kool-Aid and put it into a cup. So I cleaned them out with carb cleaner, some Q-tips, and paper towels. I had to get it jump started because I left my key on overnight, but it started up and puttered, not sounding too good but it started. I rode it up the street, and on the main road, where it bogged down at higher RPMS. So I thought 'maybe the plugs are missing', and replaced them when I got home. It died on the way home at a stoplight; jumped it again and it backfired loudly about 1/4 mile away and died again.
Today it just pops (like 25% of a big backfire), and won't stay on. I took the carbs apart again, and noticed one of the float's jet is pretty clogged. Also, all the other's would spray carb cleaner out the other end, this one just barely drips:
I am also missing the o-ring for the sync things on 3 of the carbs. Think I lost them that morning. (does this have a major effect?):
Clean from yesterday:
^gunky and dirty yesterday
This is the main jet I assume?
Carbs:
What are these:
These weren't tight, the carbs pulled off with little force, and in RED the were not completely on. Does this have a big effect?
What are all of these?: I know the red is the main jet, but thats about it.
floats:
My air filter: felt very oily/greasy- is this normal?
Also, the intake was not sealed very well. Could this affect the engine much?:
Fuel filters I put on. Good or bad idea?
Plugs I replaced:
extra pic.
1)What is probably wrong? Where is this pilot jet I keep hearing about? (wire brush bristle + carb cleaner to clean it?)
2)Is the intake and/or filter good? Does it not being attached well to the carb, and the carb to the motor make the engine not run right?
3)Do I need to take anything else apart and clean?
4) ANY OTHER helpful information would be greatly appreciated!!
Thanks, I can't wait to get riding again!

PS- The bike came with a manual, but it does absolutely jack when you aren't familiar with bikes.
