Looking for the Link to the Site where Port-Mods were explained

[camel]

hi,
some time ago, i followed a link in a thread to a site of an private person, who explained the calkulations of Port-Modifications of 2 stroke engines.
I remember he made it on snow-mobiles or water Scooters.
He explained how to grind right and so on...
Does anybody know the link and post it to me?

Thx
