Going to park up my R80GS for a quite a few months whilst I move abroad. Is there anything that can be sprayed or brushed onto the engine to keep it clean and stop corrosion?
Many things. ACF 50, Scotoiler FS365, WD40, GT 85, clean engine oil, Mr Sheen (yes really!), Beeswax, etc etc etc, dust etc will stick to most of those to a greater or lesser degreee, but when you recommision it you will of course be giving it a decent deep clean wont you....
