Doms CB550F1 project
McCabe-Thiele (Ted):
Had the SS version been available when I assembled my carbs I would have fitted one. I sourced a much better one than my original from a member here.
If the corrosion is just on the sections between the fittings a good clean up & a some silver paint is pretty good - it's hardly vissible when the petrol tank is fitted.
My carbs had been restored by Gerben & when they drilled out the pin they broke part of that bearing - hence why my bracket had to be replaced - if you decide to drill out the pin be very careful as there is a risk of the bush in the bracket splitting in two. The bush looks like some sort of bronze colour.
DomP:
Thanks Ted, I'm not sure what is meant by the bronze bush, is there any photos on you're build thread?

The bracket that the throttle rod runs through has bushes inside the alloy bracket at each end - the bushes are not available seperately. When you drill out the pin on the right side of the bracket there is a risk that the drill will go into the bush & it could split.
Updated Found a photo.

If you are going to remove a rusty one to replace it, then worthwhile using emery cloth (the real stuff) on the open rusty bits to allow passing through the bushes with reduced chance of damage.
Oddjob:
TBH Ted I think it was either Gerben that buggered up that bush or someone before him broke it and he didn't see it until he had them. I think whoever did it didn't drill all of it out, then they started to hit the rod sideways not knowing that a bit was left in, that shattered the bush.
The new Stainless Steel rods are £50 each Dom including P&P. That's not exactly cheap but you can't buy a new rod and getting an old one hard chromed costs around £65-85, I had a couple done earlier this year, the first time I had one done they charged around £25-30, then the power crisis hit and the cost went through the roof. I have some of those dog point screws as well, if you buy one I'll throw in one for you.
ATM, I only have one rod that Max made as the test one, I intend to order 3-4 more in a few weeks. However if you want this one I can let you have it so you can get on with the carbs.
