CB500/550 / Re: Stator coil cb550f1
« on: July 27, 2020, 11:44:06 AM »

Also on this subject. I am running resistor style plugs. I have read a few posts that mention issues relating to the use of resistor style plugs. I am mainly running them as I have a digital rev counter that requires resistor style for its pick up.

Any suggestions / advice welcome.


CB500/550 / Stator coil cb550f1

Hi all.

Has anyone out there in sohc land got a functioning stator coil for a cb550f1 1976 on the shelf gathering dust that I could persuade you to part with?
Or does anyone know of a rewind specialist who could repair mine? My local rewind company say that they and no-one they know of will or can do it.

I look forward to any help.

Many thanks all.

Hi all

Thanks for that info.

That mod looks like a great idea for reducing tappet noise. Thanks Ash. I think it could well be a possible fix for my rocker cover, as it’s only the very outside seat that has stretched. I’m going to look further into the drill out and bushing idea first, as I’ve just managed to find new rocker spindles and would be a shame not to use them now.

I will report back on progress.

Many thanks and stay safe.

Sorry to break the subject matter.

Can you tell me where you are finding your serial numbers on your Kei Hin carbs please?

I am currently renovating my bank and the only number I can find is 069A

Everything I have read and heard you guys discussing are numbers with a letter prefix.

Any help greatly appreciated.


CB500/550 / Can 550f1 Rocker cover

Hi All.

Would any of you guys out there in sohc land have a rocker cover for a ch550f1? It is the 8 shaft type cover not the 4 shaft style.

I have discovered mine has a worn rocker spindle seat. I am going to ask my local engineering firm if they could drill out and bush the damaged seat. But thought I may just ask here too.

Btw. Has anyone had any experience with drilling and bushing a rocker cover? It’s the outside seat that worn, no4 inlet only worn on the very outer seat.

Any info would be appreciated.

Many thanks and stay safe all.

I hope to be able to ride this money pit soon🤞🤞🤞🤞

Sad news!

I was picking up some parts from a local custom builder today, he had recently had a workshop fire and one of the casualties was a recently fully rebuilt CB750 early 70’s

A very sad sight indeed.

Hope he can salvage her?

Hi all.

Just a quick update on my progress with the rebuild.

So. I have the crankcase back together for the final fit. Just the primary shaft to fit and oil pump. I’ve been through the gears and all seems well.

Attached a few pics

Many thanks to those who have been so helpful coming forward with your advise and experience.

Thanks AGAIN! Ken

Yes! this is starting to become apparent. The previous owner had mounted the voltage rectifier just where the throttle cables run and I think this could be the problem more than the length. hard to tell at this stage as its in bits. Think I may leave buying one off cables for now. The bank balance is already suffering from this project!!

It WAS! The uk spec. Not much left if the original front end though.

I had an issue with the bike revving on full lock. I’m just getting some new cables made up with a bit extra in the length, but it would be nice to know how much wider my bars are than the std.

Don’t want to end up with them too long. My bars measure 760mm or 30” from bar end to bar end.

Hi Julie.

Thanks for the photos.

So I can take it from the pics that either will work. It strikes me that having it on the top of the mount does make more sense though.

Think I’ll go ahead with having it opposite to as it is currently.

Thanks for the help AGAIN!

Hi Again

Could anyone also clarify a detail on the throttle return cable please?

My current return cable at the carb end has a shaped/dished washer that goes around the the mount on the butterfly mount.

It seems that mine is on the wrong way around, meaning the dish of the washer does not locate around the mount correctly.

I notice on David silver and cms photos that they are indeed this way around. However in photos in the service manuals they are shown the other way around.

Anyone come across this issue before? I am having new cables made slightly longer and want to be sure of this detail.

Please see attached photo

Hi All

Could anyone out there tell me the std handlebar width for a cb550f1 I have wider straight bars on my brat style and the engine revs on full lock. Just looking into having new longer cables made and would be good to know the std bar width so I can work out how much longer to get them made.

Many thanks all

Hi Trigger

Thanks for the valuable advise. I owe you a drink or two

Hi Trigger.

Do you have any suggestions on removing these plugs on the head? Is this a drilling out job or is there a clever way of removal? I take it from your mess these are not available for replacement and need to be machined?

Hi all

Thanks for your advise members.

I agree Trigger. Very nerve wracking to think some media may be still lurking somewhere. Thanks for the heads up on the head plugs being a problem area to keep an eye on. Are we talking all 3 plugs per side of the head or just the central one on the Oil way?

Oddjob. I would be interested in taking a pair of black bearings off your hands if the offer still stands. I would feel more confident knowing the spot on size is down there. Let me know what you want for them.

Many thanks. I look forward to maybe meeting up with some of you guys this year. I take it there are members meetings organised?
