Good evening every body, I have recently acquired and s4 that is not running. I knew it when I bought it but it was too nice of a deal to pass. The gentleman the had it before had just changed battery and spark plugs. It ran for about 50 miles then it started sputtering then stalling and then dead.
The bike will crank, here are a few things that I have checked already, coils resistance are within manual values, horizontal plug will spark against cylinder didn’t check spark on vertical . Priming happens during key on, I can hear it and I have also checked by removing hose at end of tank filter see picture.
What else should I check?
Thank you.
