Topic: Cylinder 3's pipe not as hot

[2tall]

I am finally getting most of the gremlins worked out of my 76 CB550K. I have one more question for you all. (I'm sure there will be more...)

Cylinder 3 seems to be having an issue. After a ride around the block, 1, 2 and 4's pipes are all hot. 3 is hot too, but not as hot as the others. (On a scale of 1-10, 10 being one of the hot pipes, #3 is a 7 or

I pulled the plug for 3 to see if it was fouled, and it was not. I then rode for 20 minutes and pulled the plug again. Still, no real telling signs of an issue yet it's respective pipe is still not as hot as the others. I then placed the plug against the jug and it did spark. Hmmm...

Any ideas would be appreciated.

Also, how do you attach a pic? I have one of the plug, but I can't figure this thing out.

Image hosting...such as photobucket.

Then you attach the photo as a link.


As for the #3 not being as hot as the others....Have you synced the carbs?

Swap the #3 plug with another cylinder.  Does the cool pipe follow the plug or does it stay with #3?

What tune-up steps have you done?  Have the tappets been checked/adjusted?  Besides swapping the plug, swap the plug cap too.  Look inside the cap.  Is there green corrosion where the wire screws in?  If so, nip off about a quarter inch of wire.
