Dss only sell the chromed caliper pistons, I got mine on line from wemoto and they were stainless steel and came with all the seals. for around the same price as those inferior pistons from dss. so try WEMOTO's ON LINE SHOP.

Your right about the alloy oxidisation. Aparently the carbs are made af a zink based alloy and it is as if they have somehow reacted with the fuel or additives in the float bowl and gone weak. The outside of the carbs is fine.
Thanks.

I have taken my 4 carbs apart and cleaned them replacing any seals and parts that were showing sighns of age. While doing this I noticed that some of the parts inside the main body of the carbs are going chalky mainly the areas where the float valve seat fits and the needle jet carrier. I wondered if there was a cause for this or is it due to age.
Thanks.

I have been told that through use the valve tappet gap gets smaller as the valve beds deeper into its seat, I always thought that with wear the clearence would increase not decrease, which is true, anyone know?

Stainless pistons is the only way to go, I bought a pair on line from WEMOTO and they came with all seals. Good luck.

Cool, the frame number is CB550F-2110221 and the engine number is cb550e-1149106.
It would be interesting to find out the D.O.M.

Thanks, I'll let you know if I need any future assistance, as no doubt I will, most difficulties I experience are in sourcing up graded parts like for example stainless steel brake caliper pistons, david silver only sell the crap chromed ones. I have found a company called Kitek ltd who make stainless pistons using an old one as a pattern, they charged me

Thanks for the offer bryan, but I am in no real rush as theres plenty more to do on the bike, I am going to have the frame blasted and powder coated and at the moment the bike is almost fully assembled apart from rear wheel and fuel tank so plenty of diss mantling ahead before the trip to the powder coaters. Then a lengthy re assembly using new fork seals and various other seals, gaskets etc. I wanted to have a little ride on the bike before taking it apart as I've not riden it since buying it as a restoration project, but that is not essential, I also have a 99% restored cb650z which I could use the wheel from if I get desporate.
cheers.

Hi, The last owner of the bike had good intentions with the bike but took a few daft shortcuts that are fake economy. He had the rear wheel rebuilt with stainless spokes but then scrimped and used a crap, cheaply chromed rim which is now so rusty that there is barely any chrome left on it at all! So I have striped the wheel to bits and will throw the rim and have paul re build the wheel using the existing spokes and a new stainless rim supplied by him. Just hope it wont take 6 months! ride safe.

Cheers guys, Thanks to your help I now have a number of possible solutions to the problem, I will try to get in touch with paul jackson, (not in at moment) or if he can't help then I may take mathewmouse up on the kind offers to help. I'ts true about how useless most of the so called brake engineering firms are out there and even those companies who specialise in classic bike brake repairs, I've phoned loads of places with no luck. I am in chester UK. My aim is to keep the bike as it left the factory using as many of the original parts as I possably can so a repair of an existing part is always preferable to me rather than a replacement.

Hello, I have a 1979 cb550f and have noticed that the rear brake drum steel liner has warped and cracked, I am told this is quite a common problem and happens when the alloy corodes beneath the steel liner causing it to warp, I am finding it hard to find someone who can re line the drum, any one had similar problems? any ideas? thanks.

Hello, phil, The drain tubes are for over flowing float bowles and the drain screws you refer to are for draining the float bowles. The over flow pipes are like overflow pipes on the toilet system with a higher level drain hole whereas the drain screws in the bottom of the carbs are for emptying the carbs of fuel like the drain bolt for oil on the sump. Sounds like your floats are incorectly adjusted or have faulty float valves.

Thanks saxby for the good advice, I have found a chemical kit like the one you describe in frost restorations magazine that I will give a try and I will also fit an in line throw away filter. hopefully this will do the job with no more rust, cheers.
