Whilst the fairing is off i thought I'd try the Harpic trick on the exhaust headers. I was very impressed. The years of rusty oxidisation just fell off. The pipes are now a nice dull steel colour. A bit of polishing and they'll look like new. I wish I'd known about this when i had my SV's, i could have saved myself hours of slaving with solvo autosol.
the headers were far more corroded than i ever let my SV get due to them being hidden behind the fairing.
There are few versions of Harpic, i bought the power max version in there black bottle.
I'll continue the cleaning on the rear headers and cat enclosure once i get the bike into the drive.
This is just after a few minutes. Compare to the shot previous in this thread.
