I travel for my job and I did not start my R3 lately..So when I went to start the bike, it would not...Meaning if I spray starting fluid where the filter is located it will start...So I am guessing it is bad fuel or a clogged injector...What is your take on it?
I will assume with a shot of starter fluid it fires up then dies.
Try draining the tank (siphon?), add a gallon of fresh gas plus recommended dose of Sea Foam and try again, with the shot of starter fluid to get it going
