I'm ready to jump into my valve adjustment on my 02'RS. Any pointers from out there. There's a valve chain tool needed. Does it have to be a BMW tool, or can it be made? It will bve several weeks intil the event happens. I'll be replacing my air/fuel filter while I'm there. I'm going to get a Rhinewest kit, sprockets and chip. Yes, I know the stock exhaust must be used. My riding buddy and I will be doing the surgery and we both used to be motorcycle mechanics, still are to some extent. We have tools, beer, digital calipers, surf music, feeler guages, cigarettes, internet, DelMore Cigar-Malt Scotch, Arturo Fuente's.............what else am I missing? What should I expect?
