Completely Stumped engine problem
S&S 88 Evo 2600 miles
No fire rear cylinder
Replaced ignition module
Coil
Plugs wires
Still when turning over frt cylinder fires get hot
While rear cylinder doesn't.
Any suggestions
Was ridding back last week running good halfway to golf course about 5 miles started missing bad but still ran only one cylinder. Went home it went from running to it stopped. Won't run only fire like wanting to start.
Hope it's not motor damage had 15/20 pounds oil pressure when running.
Any suggestions.

I suspect you've got a valve open....

I rode back from Myrtle a(bout 250 miles,) in 90 degree heat and couldn't hear that I had a crack in the Y pipe. The next morning I went to start it and the rear exhaust valve hung up and I could hear the piston just tap it. After that, it would only run on the front cylinder too!
Op, let us know what you find...

I did put finger over hole it feels strong it blows finger off with a lot of pressure.
Guess it might be time to pull apart

Agreed. Compare the pressure felt to the front cylinder just for perspective though. Check the wiring on the single fire ignition (I assume?) and make certain that you hooked up all the wires in the correct sequence. It's probably something simple.
