Still runs weak on top speed but it runs with full throttle and that's all I need. And with the port/polish I Can't find anyone to polish/port the head so probably won't ever be done.

I think your hot and cold jet sizes got a tad reversed there lol.

Interesting that the jet sizes are very similar to those needed for a PZ30.

As far as the head porting goes, there are a couple of guys that offer porting for the CG heads that have done a bunch for other guys. Joe Henner racing or Corey from LFR Powersports.
