G111/200t base

[DillonBuck]

Working on aG111/200t and trying to get my exhaust roof numbers. After a base cut to get squish I’m at 98 degrees. I’d really like to be several degrees higher. However, the base so starting to get a little thin.

Does anyone have a rule as to minimum base thickness?

I'm no expert, but doesn't cutting the base make the exhaust lower? Semantics I know, but anyways... I don't think I can recall seeing exhaust any lower than that.

The fact that you list the China copy part number makes me think that you're grinding on one of those cylinders. If you are, it would be important for an actual professional porter to know that to give guidance, as they likely are significantly different than the real deal

It lowers the exhaust. Which increases distance ATDC. I have squish set, but want to cut the band to lower the cylinder even more.

I’m not concerned with numbers or brand……just concerned about what’s a safe minimum base thickness.

Working on developing my build on these.
Want to avoid a customer breaking a flange due to my work.

I hear ya but... As my dad often said "let your conscience be your guide" Nobody (really) knows dick about china alloy. In other words, you are probably already there...

Other than opening up the exhaust port a tad there isn’t much to do on the 020t and 200t cylinders that will gain much. They really are pretty dang good as is.

Pretty dang good can be made better.
Most saws that get ported are already pretty dang good.
