2016 900 s eps. Ran perfect. Shut it off. Washed it. Started it and moved it to the building. Went hours later to ride and big backfire through the intake manifold blowing it into 5 pieces. Replaced it and tried starting it again and this happened again. Replaced it the 3rd time and reset timing. New chain tensioner. And one way bearing. After test there is no injector pulse to the driver’s side injector. Tried to start after retiming it and it backfired through the exhaust couple times then the intake blowing it off the boots but not apart this time. I’m lost to what could be causing this issue. Both injectors are good they have been swapped around. Fuel pump is kicking on and reads 60psi on my tester with a slow leak down. If not cranked right away. Bounces from 55-60 psi while cranking. I have also replaced the cps. Someone please help.
