I know, zero rust is desirable, but I'm posting this for opinions as to what you guys live with (or not). New to me CL450K4, new paint on all the steel bits so I don't want to use anything caustic to clean the tank, so would probably go with the vinegar and chains method. Before I yank the tank and start that process, what is the collective's opinion of this rust? The pictures show the rust which is above the fuel line (about 1/2 full) and the gloved finger pic was wiped from the dry top of the "hump" in the tank, above the fuel line. Should I just run it or mess with it possibly causing stuff to break loose later and screw up my carbs? It's only got about 75 trouble free miles since the rebuild so no telling if it is a ticking time bomb or not. Thoughts?
