Honda-SOHC

Hi,

I’ve finally got my 550 on the road and riding for the first time with me just in time to catch the last of summer - (since I think 1999). A lot of titivation changing and rebuilding carbs, fork seals, tubes tyres, electronic ignition, servicing and lots of cleaning up.

I am sussing out some teething issues since taking it on short journeys where I live to try and make it reliable. It has broken down on me a few times but nothing a little roadside fix and cleaning up and improving electronic connectors didn’t solve.

However my latest breakdown blew the 15a main fuse losing all electrics to the bike, luckily a spare was there which allowed me to get home - something to note is I rode the bike for about 5-10 mins with the headlights on for the first time when the fuse blew. With this in mind I rode home using only the pilot lamp which seemed to be fine, around 2 mins from my house I switched my headlight back on which lasted the 2 mins home blowing the main fuse again right outside my house. The headlight thing could be a coincidence but they do also seem abit dim even though the bike charges.

Has anyone had the main fuse blow?

My plan is to replace the fuse box for a newer blade type anyway checking for any bad connections along the way.

Thanks for any help

I’m putting my front wheel back together after fitting new bearings but I think the brake disc bolts have been put on incorrectly.
I have fitted these nuts as they work with the lock washers (already fitted). However I have looked at pics online which looks like the original nuts don’t use lock washers. Before I had the original nuts which I plan to reuse. Am I correct in thinking no lock washers are meant to be used? The originally nuts have like a flat bottom which wouldn’t allow a lock washer to be bent over to lock. Can anyone help?

Hi,

Does anyone know where to source a wheel bearing kit for the front and rear including all the seals of decent quality? I’m struggling to find a kit with everything in it.

Also are there any differences between the 550f and 550k?

Thanks for any help

I’ve noticed you can get a Dyna S ignition plate to replace the points as an upgrade to improve starting and smooth running.

I’ve also found a unit on David Silver spares. ADACA300505P this is the part number, it says this is a good quality Japanese part and sounds tempting at a good price. No extra parts needed.

Has anyone got any experience with either and can let me know if they’re worth getting?

My bike is completely standard at the moment running points. Cb550F 1976

Thank you

Hi all,

I recently got a set of Keihin 069A carburettors in rough shape and plan to clean them up an run them with pod filters on my 1976 cb550f bitser.

I’ve had a look at all the vital rebuild parts and they all seem like they should clean up and be functional 
except for the small cap that is missing in the photos. Please see attached.

My question is, does anyone know where I can find a replacement cap, plug or whatever its name is. And if left like this would this cause an air leak?
 
These are located on the end of the shaft that operates the slide at the top of the carb.

Thanks for any advice

James
