Power Cylinder Assembly CLEARANCE

Put this in and my HAE01 started running smoother than it ever has. The piston fit is noticeably tighter and more consistent than the original part I was using.

The cylinder walls are nicely machined and fit perfectly into the HAE01 frame without any need for sanding. My engine is running smoother and has noticeably more consistent power output during the full cycle.

Finally got around to installing this on my HAE01 and the fit is spot-on, no filing or shimming needed. The cylinder wall feels smooth and the piston slides without any catching, which makes a huge difference in how smoothly the engine cycles now.
