So you did or did not have them separated ? OK, let's start here; remove them (you don't seem adverse to work) and look at the throttle plates from the engine side. All should be in the exact same position. Without the cables attached, you should be able to turn down the idle control and have all throttle plates close completely. Any that don't must be addressed. I believe that the linkage between the individual carbs is not correct (I'm assuming you had all separated) An inspection of the position of the throttle plates may confirm this. The individual carb adjustments may be used to insure all plates can be closed completely. once all plates can be at completely closed at rest without the cables attached you can procede with re-installation. If the throttle plates were changed along with whatever other parts you did, the plates may not be centered on the shafts. We'll get into that later. First confirm that you can or cannot close all throttle plates. This is not a new or unknown problem, it happens to most people who dissassemble too much. That's why we recommend doing carb work one at a time and not removing them from the "runner".

So I had 2 sets of carburators for my motorcycle,I savaged both and i took the best parts to rebuild the new carb set so I bought from Honda many parts, the jets slow are new, the jets main new,all floats level new,also all the gaskets, 2 valve floats are old but still in very good condition and 2 are new,the vacuum pistons are old but they look like new.What I did is first i took photos before i started my work and after that I disassembled all the carbs in sequence, then it was easy to rebuild .I cleaned inside the carbs with a good degreaser . After that I rebuilt all the carbs together. For the pilot screws I pre set them like honda wanted 2-5/8 turns out.I loose all the cables (throttle and choke).

Take your time and write out slowly what you did (and why) so we can have a better idea of what you're doing. Give us some history of this bike and what caused you to attempt to change whatever. Don't try to be brief, write a book if you have to. The more we know, the easier it gets to help.We need to know if you separated the carbs from the runner and what parts you disturbed. They were removed, right ? > > --- On Sun, 2/8/09, wanetor <[email protected]> wrote: > From: wanetor <[email protected]> > Subject: [Nighthawk Lovers] Nighthawk CB550CS Idle too high > To: "Nighthawk Motorcycle Lovers!" <[email protected]> > Date: Sunday, February 8, 2009, 8:08 AM > > I change all the parts of my carbs and also i loose all cables but my > idle goes at 5000 rpm and more .
