    What is this is my #1 cylinder?

    Lost compression in #1 last summer. Finally got to tear into it today and found this in the cylinder. Looks like a boot for something. Not sure how the hell it got sucked in but there are pieces stuck in the valves holding them open. Any ideas fellas?

    Those are stiff metal threaded pieces? The piston walls and rings are ok? Check the intake side above the valves. If they're stiff they couldn't of come through the intake side but they don't look like seats. You were riding it when this happened?

    I was wondering that. I had a hell of a time getting the block off plate in last year. I thought there was just an o-ring on it?

    That's got to be it. Thanks for finding that for me. I still can't believe it managed to get past the valves into the cylinder. It was missing a little before it lost everything. Now to get the crap out of the valves and put it back together.
