I know Jack has been hanging around the forum a little bit now and I have been looking over his info in the 650 garage. I am starting to get into head porting and experimenting a bit. A lot of his info is written down and described pretty well, but all of the pictures are missing. Also his info on basic head porting is missing too. Does anyone know if that info with pics is floating around here somewhere? Or has anyone saved it for future reference? He's a wealth of knowledge, and I think it would be good to see that info here as well. Jack- if you are reading this please feel free to chime in.
