I made do with notes taped to the tank for years.
Then started using a Garmin car sat nav in a waterproof phone case. It was a bit hit and miss everytime I went around a roundabout the screen would flip and it would get confused.
My Guzzi had the provission for a TomTom so I tracked down the mount and sat nav to go with it. Its old but works well and only cost £50 on ebay  :)

I have put some pictures with measurements somewhere on this forum, don't ask me where. There are two different brake plates with different size brake cam, different brake shoes  ;)

Nice work, it looks like you're making leaps in the right direction to getting it back on the road again.

I'm keeping my fingers crossed that cleaning my carbs will be as straight forward when I get to them shortly!
To cut through the shell marketing bullox,  those two are more or less the same spec as each other.

They both meet diesel rating of CF too.

The statement for the shell " uses both mineral and synthetic base stock" is more or less there to justify a higher price.

Neirher should give a problem,  bulk is significantly cheaper to by if you're going to use the quantity.

So I'm still ok to use the shell oil and don't need to rush off to the shops then? Long term it would certainly make sense for me to invest in a larger quantity supply, good point well presented!

Just seen that you're in Wimbledon, you must only be about 15-20 mins up the road from me in Hinchley Wood. Do you get out on your bike often? It would be great to compare notes with some other owners and kick tyres at some point.

Most likely it's from a 550F or a 500K. They used different brake plates and they will foul. Any markings on the inside of the drum, most have some identifying marks, it could be a 750 rear wheel as well, did it come with the sprocket carrier on? those are also different between models.

Maybe post a few pics to help us isolate what it's off.

I bought one from DK a few months ago Florence, he had a couple for sale at the time and I chose the best one I could find. He may still have others they haven't advertised yet, maybe a phone call to them would help.

If you weren't so far away etc I'd have lent you the tank as I don't expect to send it to Menno for a while yet.
CB500/550 / Re: What is a realistic lifespan for a CB500/550 camchain?
« Last post by Oddjob on June 04, 2020, 08:42:40 PM »
Might have been an idea TBH but manufacturers state lower than what the chain can last just to avoid some liability in case of a chain breakage. Like most things, take care of it and it will last longer, change the oil regularly and less detritus is wearing away at the linkages etc, keep it in constant proper tension and that also helps. When I was racing my 500 I changed the chain frequently as the engine was being thrashed, when I stopped racing it used to last around 30-40K depending on how heavy my right hand was.
