CB500 - downpipes

[ajb]

I've had my CB500 since August, when I got it the downpipes were black (looked freshly painted) but in the 4/5months I've been riding it they have gone reddy-brown with rust.

How fast will they rust through ? Is it imperitive that I re-paint them now ? I know it would be good practise to do so now, but are they going to crumble over this winter ? If so, anyone recommend a decent paint that is easy to apply ? (spray?).

Thanks.

PS. Just got myself a fenda-extenda.

I used cylinder black.(but BBQ paint also works)
You can buy it from halfords i think.You should do it straight away,just rub and surface rust off then paint it on with a brush.
Takes less than 10mins to do.

the wd40 just burns off anyway

I found a fender extender and bbq paint the best solution. not perfect but certainly a good option.

Painting externally won't do that much good, as downpipes tend to rot from inside out , unless they are decent quality stainless at which they still rot just slower as stainless passivises, (which is why its a bad idea to clean stainless), and forms a protective layer when it decays on its outer surface..


Unless your bike burns loads of oil there is no stopping inside out rot.
