Was cleaning project bike yesterday and found corrosion under the rear hugger around the bolt holes, grrrr! Assuming this is acid corrosion likely to have pooled there during its apparently many cleaning/detailing episodes? Also found lots of white powdery residue in the swingarm - cleaned out the hole for the brake line clip and this residue was well packed in the hole - thought it was cleaner residue, but seems like loads of it - wonder if the swingarm has been shot blasted or chemically prepped as does seem shiny. Does the rr6/rr7 swingarm have some packing material inside? . Not sure if it's time for replacement!
