OK, spent the entire weekend working on the cb550. I dont normally spend so much time on her but I have let the rot set in a bit the last year or so, and havnt invested any money at all for a lot longer. Its starting to show.
She has a couple of bad oil leaks from the oil pump and gear change oil seal. Not normally a problem but it is covering the chain and hence my back wheel in oil. (better than a scottoiler though!).
I have a new rear tyre on order so decided to tackle at least one leak. So had a go at the oil pump, by far the easier to fix. Ok no problem so far. Cleaned air filters, plugs, checked cam chain, valve clearances and timing. Changed oil. Started on the front brake system, It squeeled really bad.
Thats where it all went wrong.
Ive poured about 2 litres of brake fluid through my master cylinder and all I get is sponge! Its a relatively new piston so ive cleaned that and reused it. Fluid seal was replaced. Normally, when I get this much pudding in a front brake I suspect the piston seizing. But its good and moves freely. I can only suspect the master cylinder has decided to lay down. It is original and never been serviced.
Ordered new pads, Master cylinder assembly and bleed nipple.
Then, as im wheeling the damn thing off the drive to bed the pads in, one of the carbs starts gushing petrol! Lovely.
Its beer time now.
Cheers
