Katana Carb Problem (HELP!)

Hi all,
Ok, here's the deal. Last week I was messing with my 2001 Katana and
trying to bring up the idle speed since it was lower than what the
specs said it should be. Here's where I admit that I did a stupid
thing... I adjusted the inside carb synch screw thinking it was the
idle adjuster since it was right next to the throttle cable. Note: At
the time I was doing this the engine was running. I realized pretty
quickly what I had done and wasn't all that worried because I'd been
wanting to get a carb synch and synch them anyway, so I shut off the
bike and ordered my Hg Syncher from JCWhittney.

So, here's where my problem begins... After I received my synch I
went back out to do the job and now my bike won't start. AGH!! After
a lot of tinkering and pulling off the carbs and visually adjusting
the butterflies according to the manual I was able to get the bike to
start and run at a very low RPM (but it didn't sound happy). If I
even tried to raise the idle at all it would die, so I attempted to
synch the carbs at about 700 rpm, but after I did, it still was having
the same problem. I'm at a total loss. I'm not sure if this matters
or not, but during my own stupid trial and error diagnosing, I sprayed
some carb started into the carbs to see if I could get it to run and
it did, and if I sprayed some into the carbs while it was running the
idle would dramatically increase (which I can't get it to do with the
throttle without killing it). I'm not sure if that helps, but I
thought I'd throw it out just in case. It seems to me that I'm having
a fuel issue, but I can't see how my bike went from running fine to
not running at all with only a little help from me. I've been
debating on pulling them apart and cleaning them, but before I do I
wanted to get some other suggestions since I really think it's going
to be a waste of my time since the bike is fairly new.

Thanks for any help you can give me!!!

You have replaced the airbox and checked all your carb boots for leaks, right?

Another Tim

 

I guess I can double check that the intake boots are sealed. I would
have guessed they were, but anything is possible.

As far as the other suggestions made... Nothing was caught up in the
intakes seeing that I did all of this with the gas tank off of the
bike and the airbox was removed as well.

Thanks for the suggestions,
Tim

 

Ok, so I have my moments of stupidity. Yes, I was trying to synch
the carbs with the airbox off. I plead ignorance. Thanks for
pointing me straight. I will try again.

Thanks,
Tim

It's always a pleasure to work with another Tim.

 

Hello Again,
Ok so putting the airbox back on seemed to improve things slightly,
but I'm still having problems. It will run upto 800-900 rpm without
dying and if I give the throttle a quick pull I can get it up to 2 or
2500 rpm, but I have to let go immediately or it will kill it. Also,
when I first started up the bike, I "turned on" the starter (enricher)
system and the bike idled probably around 2 or 3000 rpm for awhile
before I shut the enricher off. Any other suggestions?

Thanks,
Tim
