Questions:

-I cut maybe .5mm past the outer edge near the opening edge, it happened when I was blending the stock port into where the template mark ended (template isn't as long as the stock secondary port). Is that a problem? Could I actually extend it out that much the whole way? Would I want to? That is where the side seal/corner seals ride, right?

I know, I should get my e-shaft and a rotor out there to check things out that way. I probably will before too long. I won't be able to do much else today though.

-Should I cut deeper at the closing edge? I only angled the opening to the template line. I've seen some ports go very deep there, and from what I've read I don't want to really do that, BUT I suspect I may benefit from ending the slope (meeting the stock opening) about 5mm lower.

-I also want to know if I should cut the template just to the line or cut the line as well.

I know I can also cut a little into the control ring area, but I would prefer not to do that with this motor. Although I guess if I cut the template out like that then that a little control ring surface would be removed...
