Sorry to hear it Don. See my recent post - "RUST".
Inspecting my bike after several months in a damp garage with a dust cover on gave me a bit of a shock too! Like you say - it's a heart-breaking moment.
I have at last brought it back to almost its former glory, although I had to replace the mirrors (rusted to buggery). The wheels had small pits which came out easily, but most of the rest of the chrome - tank & mudguards - was OK (regularly waxed). The Golstar exhaust had just a few minor pits, easily dealt with. Downpipe was ok. Brake pedal & side stand were well pitted, but fairly easily restored. Aftermarket chrome rack/sideframes pitted but not too bad - I'm leaving it off until I need the saddlebags for trips away. These, and the leather tool roll, had mildew. Some paint lifting from parts of the frame, now sqirted with ACF50. The alloy engine covers etc are pitted alas, and will never look new again, but still shine up nicely with a bit of elbow grease. The bike (11 month old G5 DL) is now gleaming and sealed in a bag with plenty of dessicant and a humidity readout, until the sun comes out again.
A hard lesson. I'll be a lot more vigilant and liberal with the wax in future.
Or I might just crate it and ship it out to Australia and go live with my bro.
Year-round riding weather and no corrosion worries. Imagine. Bliss......
Think yourself lucky you didn't buy the new Bonnie, which needs to be washed and dried after
every ride or the warranty is void!! I kid you not.....
