Hi everyone, hope you’re all doing ok in this crazy time. I’m looking for advice on taking care of my Bonneville T120 engine casing. It has some white discoloration and I’m wondering what I can do to treat it. Any advice would be appreciated.
Agree with Nick that apart from a bit on the edge of the fins and the bolt heads most of that looks like residue from chemicals (cleaning or otherwise) , maybe when the engine was hot.
you haven't been using specialist motorcycle cleaners like muc-off have you?
That stuff leaves a nasty residue if the engine is even slightly warm.
Maybe try WD-40 with a stiff brush or toothbrush, I usually give mine a wipe over with WD or gt50 after cleaning to give them a darker more even finish.
Clean up the edge of the fins with very fine wet and dry on a flat block and then protect with acf-50.
