I just repurchased a 2005 Suzuki M50 that I bought brand new in 05. I rode it for 2 years with no problems,then sold it to my brother-in law who lost his license that same month.Long story short the bike sat for 4 years and now I cant get it to start. I put in a new battery and changed the oil before attempting to start it.The first time the speedo rolled over and the FI light lighted up like it should,but it wouldn´t start.I took the fuel tank off and dumped the old fuel out and put in about a gallon of fresh fuel and a dash of Marvel mystery oil to help clean the injectors and used some starting fluid and it will almost start but not.Any suggestions? Any assistance would be greatly appreciated.
