Nope. Bdc. I put the one cylinder on there, and took the other rod and pulled till it wouldnt pull anymore. Plus, tbe piston was also reating on the crankcase. I checked. 100% positive its bdc
Oh yeah, that makes sense, carry on.
You want the exhaust port perfectly smooth and polished, and the transfer ports smooth but with a light texture to them(at least that's how the cylinders I just got back from porting were done)

It is lmao its resting on the bottom of the cylinder. Plus, i pulled up on the other rod. Thats bottim dead center
You have it exactly backwards. Intake is rough, transfer ports opened up a bit and smoothed but with a rough surface (like smooth grit sand paper) and polish the exhaust ports till theyre like mirrors. When you think the exhaust ports are smooth enough....theyre not.... keep going smoother. Like perfectly spit shined boots. I start with sanding rolls on a straight die grinder, then go to the rough side of emery cloth, then the back side of emery cloth, then to 320 grit cloth, work my way up in grits to the 1500 - 2000 mark. Then finish it off with bits of micro fiber and simichrome polish.
