94 600 idles at 12000rpm

[joeA]

ok. Do just bought a 1994 600 katana. When I bought it the bike didn't want to idle at all so I took the carbs off (mikuni) disabled and cleaned everything. Now, I have put everything back together and she fires right up. The problem now it's it idles at 12000rpms. I've never seen anything do this before. Please help

Did you sync them? Check for binding linkage.

[joeA]

No binding. I did not sync. Didn't take the carburetors apart from each other and the carbs open at the same time. I can't leave the bike running long enough to do a proper sync.

I did not sync.

That is what's called "answering your own question".

[maniac1886]

you will need to pull your carbs as bench sync them, then put them on and sync them while the bike is running.

[joeA]

Thanx. Will take them back off and bench sync.

Remember that you can easily bench sync them by adjusting all the throttle plates closed, then engaging your idle adjuster enough to get the desired result. Just don't forget when you're messing with your idle adjuster and tuning that you can actually kill your bike using your idle and it won't turn back on until you've run the adjuster up again. Ask me how I know.
Follow up with a proper sync, idle drop, and proper sync again - you won't regret it.

Thanx again for the help guys. Didn't have a chance to work on the bike till tonight. But here its a lesson for me to check all the stupid stuff before I look into the major things. the intake clamp behind the #2 carb was making the throttle array open. Should have checked that when I looked for the cable binding. Will be doing a proper sync on her tomorrow night. Again, thank you.

[92xjunker]

I thought so..... And you told me it wasn't..

[joeA]

yeah I know, my bad. Didn't even think to check that when I checked the cable. Thanx again man.

If the throttle was being held open, be glad it was only idling at 1200 RPM. That usually causes a much higher idle.
EDIT:
I don't know why I was reading that as "1200". Yeah 12000 sounds more like it.
