Any advice or help
This is what I know right now on my 2007 Vulcan 900. I was driving home after leaving shop where I had a new front sprocket, belt an rear tire put on made it maybe 7 miles an bike changed pitch out the exhaust. Gave her some gas an had no power. Rear cylinder was not firing( exhaust cold to touch) trailered her home an started looking
1. Coil is good ( swapped front coil an back coil. Front still runs fine)
2. New spark plug
3. I checked injector it makes a click, also did it while running gas came out exhaust. Also check power at injector good
4. Misted gas in to cylinder an cylinder fired an exhausted heated up.
Is there a relay or something I'm missing has anyone else had this problem
