cb550 idle jets
« on: December 31, 2010, 11:41:30 PM »
  So I've been sniffing around trying to find the proper replacement idle jets for my cb550.  I believe my bike is a tad lean in this range judging from the plugs, that and the fact it's a little difficult to start, even more so when it's cold. 
 
   I haven't been able to find any replacements other than jets-r-us, and even then they require you cut 4mm from the butt end before they'll fit. 


 
   I was fiddling with some early 750 carbs I just got in the mail, the ones with the screw on top.  What's the model designation here?  Turns out these idle jets, keihin size 40, are a direct fit to the CB550 carbs, the 067's.  I can now up my jets by one size, but I'd like to have at least 2 more for high elevation riding.   I'd like to refrain from having to get the jets-r-us items and modding them. 

   Has anyone else found early style 750 or 067 carb idle jets for sale that don't need modding to fit? 
Just call me Timmaaaaay!!!

I've never ordered from here - but I found this site a long time ago. May have what you're looking for. Maybe check the seller page to see if anyone has had good/bad experience with them. They definitely seem to have quite a few jets...

  Nope, same deal there.  Somewhere along the line, it seems Keihin started making part # N424-24.  The specs for the diameter of the base and the thread size are the same as the original jets, however they're about 4mm to long.  And like I said before, and this is so silly I can't believe they suggested it, Jets R Us told me to just "cut off the end and cut a slot for my screwdriver".   I need a lathe.

Hey Broshi,

Check out this link.  I've dealt with these folks before (usually through Ebay), but have always have good luck with them.  I'm not really current with the 550 but I hope that some of the jets here might work for you.  I know there is some Kester stuff (yikes), but I think the jets are made by a different company.  Hope this helps.  I know they don't give dimentions, but then just call them I did and they were very helpful.
