I am getting ready to pull the trigger on buying a used yz450f that has been sitting for a while. I noticed some galvanic corrosion on both outer fork tubes at the fork guard wear clips. the tubes are pitted locally at the clips only and not bad enough to loose the clips...not even close. Sorry i don't have pictures but to try and describe it...kind of looks like electrical arcing occurred in several locations around the clip producing a white/grayish powder ans pits. I think it is just cosmetic but is this a sign of a bigger problem? It is a FI bike if that makes any difference, Rest of the bike is super clean.
