The exhausts are stainless, so I don't think chrome cleaning products would be indicated.
As far as the old T goes, usually the culprit was water in the spark plug boots or in the distributor cap. The V11 has no dist. of course, and the caps are soooo much better than the old ones.
I'm bad about washing my bike- real bad- like twice a year, maybe three times at most. I spray on S100 on the hard metal parts that pick up oil and dirt (engine block, rear drive and wheels) then liberally hose it off- not spray, just light running water. Then I wipe down everything up top with a damp rag or I use some simple green sometimes (again with lots of water). Seems to work pretty good.
