I purchased my 02 RC51 last week from a guy who only put 480 miles on it and just let it set for a few years. I am now having problems where the bike is running extremely rich. I completely siphoned out the tank and ran the bike out of the bad gas. I also put in new plugs hoping that the computer would correct the gas exchange. The bike will stall out at a complete stop or when I approach a red light. I am not for sure if I have clogged injectors but would appreciate any advise from someone who has experienced these same issues. Also, what is the cost for this issue and will I be able to do it myself or should I let the honda mechanics tackle it.
