Speckled rust on header pipes.
Athame57:
Before I enter into too much sweated labour, is the speckled rust one finds on the header pipes especially close to the cylinder head the sort of rust one can remove or is it too much from under the chrome?
Skoti:
You could try a rag coated with solvol autosol, loop it around the pipe and tug it back and forth.
Won't completely remove the rust spots, but gives an acceptable finish I think.
Good luck

K2-K6:
Chromium doesn't corrode (primary ingredient in stainless steel to avoid this) meaning what you see when chromed parts show rust is that you're seeing the ferrous structure corrode and poke through the chrome plate.
If it's taken off then ultimately it'll just come back again as only temporary dependent on conditions. It'll certainly improve appearance if you polish it off but there's not much in the way of wax etc that can live with exhaust heat to prevent water getting onto it again.
The rust treatment we were looking at on another thread, that flow product does seem to convert and give some level of protection to exposed steel rather than flash corrode after treatment.
Very rudimentary test, but some of the tools my son treated (some were really really rusty) have been left outside for three weeks without showing any fresh corrosion. Maybe of some value to convert the oxide and produce an element of resistance against further corrosion. Just an observation on that angle.

Still ok but have never seen bad weather and bike kept in a vac bag over winter.

Hi Deano
So there is hope yet! If I had known what a vac bag was ( just looked on google) I'd have got one along time ago. Thanks for this! ;D
