    2 stroke help gp1300r

    Hey, I recently acquired a 2004 that "ran when parked" 10 years ago. I took plugs out to check compression and cylinders were full of 2 stroke oil...shot up to the roof of the garage. I am a fairly capable 4 stroke guy but am a little stumped about how this would happen with the oil injection system. Also rear cylinder of the 3 has no significant compression.....seems even worse than rings could explain. Could it be a stuck "power valve"? No holes in piston.

    Best regards and thanks for any help.

    I am also used to 4 strokes and am learning 2 strokes as I go. You can pull the PV covers off and see if they are still connected. You’ll clearly see if the PV is out of the lever.
