I installed a “Cobra Fi2000 Tri Pot EFI Controller“ on my 2019 Kawasaki Vulcan 900 Custom. The instructions stated it was already set for my bike so I did not change any of the settings. After a 40 mile ride I noticed it was backfiring when I changed gears from 2nd to 3rd. It also smells like it’s running a little rich. Can anyone advise what adjustments I need to make. Thank You in Advance.
