CB550 refurb

[Johnny4428]

I fitted this DS master cylinder kit a little more than a year ago. But it has failed big time. Not just a weep but a pool on the floor in the morning. Not even riding the bike! I would say the rubber is a touch hard and don’t like the fact that you can insert the plunger with little or no resistance. Bore in the cylinder looks fairly descent, so the question is where can I get a reliable kit from?

Buy the ropo master cylinder instead

If its laid out as it was assembled it was done wrong, the loose lip seal shoul be aginst the piston and the hard cup at the very end

It was assembled the correct way Bryan, doubt if would have worked the way it’s laid out there, it was just a pic of the removed parts. I ran the bike last summer with no issues and not a drop of fluid leaking, because I had renewed the seals and internals in the cylinder. The master cylinder looks to be in good condition for age, had it been otherwise I would have replaced it.

Master cylinder assembly complete, cheaper than an OEM master cylinder kit!😳 maybe a no brainer.

I looked out CB500T kits.
They tend to be cheaper. Paid a few quid less than this.

Thanks for the link there, I’m going to take another look at the cylinder bore before I order.

[Johnny4428]

After measuring the bore in the master cylinder which was well within spec, I ordered another repair kit. Picture shows bit of difference in the piston seal diameter.

Thought since it was a nice day I would have a go at painting tank and side panels. Disaster!!
I know there’s a lot worse things going on in the world right now, but no one could have convinced me this morning thing is I dont know where the flakes are from, I’m thinking the paint has maybe sat about for too long.
Unless someone else knows better. Thing is the filter sits at the bottom of the paint cup so it can only come from the paint or cup.

Thats bad news Johnny. I am not a painter so unable to offer any clues but on the bright side........its still sunny for a few hours yet so go for a ride and you'll feel better about it

After giving up on the freedom green dream I decided to go with Candy Jade Green, finally getting round to putting some paint on yesterday. I wasn’t convinced it was going that well giving the light I had but after taking a side panel out in the sunlight and dropping a side panel badge on it I am reasonably pleased with the way it’s going.

Nice work Johnny. I envy those of you that can paint, not in my skillset I'm afraid, it never turns out well despite plenty of prep!
Well done, great colour choice👍

[DomP]

Absolutely love that colour, nice job!

[Laverdaroo]

That looks great Johnny, as Don said, ace colour.
