A loose sparkplug cap caused huge problems on the 23-26 TBI bike. Ran blubbery and fouled plugs
After dealing with some low end blubbers and fouled spark plugs, that came out of nowhere, I found that the spark plug cap was coming off. I cut 1/2" off of the end of the spark plug wire, screwed the cap on until it was tight, and no more problems. An instant fix and a whole new bike
