I have a 2009 M50 with 4100 miles that had a issue this week where I had a fire in the exhaust and now runs poorly after the fire. I was driving down the highway at about 70 miles an hour when I had a loss of power but still running and I started looking around to see what’s going on and I saw flames coming out of my exhaust pipe. I pulled over immediately and the bike still starts and both cylinders are running but the one that had the fire is running very rich. I want to change out the injectors and I’ve never worked on a bike like this before but I have worked on smaller ones and I’m fairly handy.
I tried replacing the spark plug but made not difference and seems like it is just getting too much fuel in that cylinder.
I have the motorcycle seats off, gas tank off and now I am just trying to locate the fuel injector so I can try changing them and if anyone has any advice of where they are or how to take them out it would be greatly appreciated.
