CB500/550 / Stuck in the middle!
« on: July 17, 2020, 09:18:30 PM »
It maybe hovering about the middle somewhere, but I had a lovely 75 mile ride on my trusty old 550 this morning. Since restoring this machine I can honestly say this is a very enjoyable middle of the road machine (even with its PD46A carbs)! Certainly wouldn’t swap for no modern “crotch rocket”!

CB500/550 / Cb550k3 Rectifier
« on: June 28, 2020, 05:57:45 PM »
Hi everybody, anybody cruising today? Went for a run just about 18miles switched to reserve fuel on my return to town so filled up, pushed starter button wouldn’t even turn over, thank god there’s a kick start lever. I came home checked voltage on battery 11.3 volts! Not good. No power whatsoever getting from alternator to battery. I have a suspect rectifier with a slightly fried red/white wire. Question is replace with just rectifier or replace with regulator rectifier. About the same cost wise from what I’ve seen so far.

CB750 / CB750K3 replacement Seat
« on: June 20, 2020, 08:55:30 AM »
Hi all, Any recommendations for the replacement seats from P&K Classics. I had my 550k3 seat refurbished by them and I was very happy. Just wasn’t sure about the reproduction base etc. Looking for 750K3 seat.

CB500/550 / PD46A setting
« on: June 08, 2020, 10:41:41 PM »
Hi all, can anyone tell me what the base line setting is for the pilot system for my K3 as my Haynes doesn’t even cover these carbs. They are set 2 turns at the minute but I have a feeling they are supposed to be 1 1/2.

CB500/550 / CB550K3
« on: May 31, 2020, 07:13:07 AM »
Has anyone on this forum had to use a series of ratchet straps and levers to fit a replacement set of exhausts which are supposedly been designed and manufactured to fit your particular model.  >:( >:( >:( I suspect I’m not the only one, very annoying to fit to a newly painted frame without damaging or chipping. These pipes were purchased a few year ago I’m hoping that they are better now.

CB500/550 / Handlebar control lettering paint.
« on: March 03, 2020, 07:11:27 AM »
Hi all, anyone know what an appropriate colour would be for a 1977 CB550K3 handlebar control paint would be. I read somewhere that it’s more an orange rather than a red. I’m not sure so I appeal to the knowledge and power of the forum.

CB350/400 / Check your ENDs
« on: October 26, 2019, 09:07:37 AM »
This I discovered last night checking the electrics, timing etc. Trimming the HT leads and reconnecting, this screwed off with the cable, not much holding it!

Misc / Open / 40 Year Confusion.
« on: October 16, 2019, 06:59:38 PM »
Hi, Can anybody shed any light on this 40 year old bike rule for gaining status of VHI. I have just taxed my CB550K3 and it set me back £66, despite declaring the bike to be 40 year since first registration. (Feb 1979) Although strangely enough I managed to tax a vehicle that didn’t have a current MOT. Not wanting to question the teller in the post office I thought I would contact DVLA when I arrived home. I contacted the very helpful assistant on the online chat facility on DVLA web site and after a few lines back and fore she informed me that my bike would eligible for VHI IN April 2020. I informed her that I was not any clearer on the 40 year old ruling reminding her that my bike would be 41years and 2months old then. Although my bike was actually built in 1977. Which I am now in the process of having to prove.
Anybody else faced a similar dilemma.

CB500/550 / Tank Badges
« on: July 18, 2019, 05:26:58 AM »
Hi all, Somewhere in this world I am the owner of two tank badges for my restored cb550k3. I just don’t know where, maybe in the house garage or with the fuel tank restorers. If I ever find them I will be keeping a firm hold of them. Which leads me to ask the question, has anybody got one or more of these that they are willing to sell, loan or give away? If so I’m sure we could come to some arrangement. These are the ones with the pins on the back, not the ones with the holes for screws.

CB500/550 / Felt seals on carbs.
« on: May 31, 2017, 08:52:39 AM »
Hi all. Anyone have any experience with replacing felt seals on throttle or choke shaft on carbs. The reason is I had one disintegrate when I was cleaning carb, and that was just with a cotton bud. I would replace them all if I could get the seals.

CB500/550 / PD46A Carbs float vents
« on: May 23, 2017, 11:02:59 PM »
Can anyone on this forum tell me the spec for the vent hole for the float chamber on the left side of carb body. I had a carb cleaning wire that I was using to clear the hole, but unfortunately you know how things have a habit of becoming a stranger to the script? yes I snapped the wire inside the small passage. aaaaaaaaagh. But then I thought I was none worse off because it was blocked before! Except this is undoubtedly going to be more fifficult to clear, Any thoughts?  I take it these passages are quite important to the proper running and prevent a vacum or pressure forming in the chamber. Any help advice would be appreciated.

Misc / Open / Improvisation.
« on: July 15, 2016, 08:41:18 PM »
Hi all. During my rebuild of my cb550k3 engine I found myself short of the large valve Spring seating washers by the tune of 6 wtf....Thing is when ordering spares I had ordered 2 in case there was ones missing, still short of four! Since sorted. When I was replacing rocker cover found to be short of 1 dowel, despite relevant labelled tubs with all parts, at least that is what I thought. But great improvisation with the help of a good 10mm drill bit now 16mm shorter than it should be. Nevertheless very happy to have replaced valves and that pesky little collets without losing any. After 6 months of being p....d off with one or two things that didn't quite go to plan I am finally seeing the project progress.

Misc / Open / Singing the praises of SOHC.
« on: December 10, 2015, 09:42:00 PM »
Can I extent my gratitude of the forum, by saying that I am one happy bunny after receiving from Spain a very nice seat for my CB550K3. I don't need to tell anybody here that these seats are getting hard to find especially in this condition. Special thanks to Piki. Incidentally I have a seat I purchased for my bike off eBay from a 550f, I sebsequently contacted a bike seat restorer to have the seat refurbished with the correct foam and cover and was told that the seat is totally different. Well unless anybody knows different it would appear that the seat pans are exactly the same.
