blacksheep Posted November 8, 2009 Report Share Posted November 8, 2009 Can someone tell me what kind of porting i have on these cylinders? i purchased these locally and they where on the guys bike that sold them to me when he bought the bike. They have Varner scribed on them. Googled search says they where ported by Terry Varner a very popular dirt bike porter.

crustydemon Posted November 8, 2009 Report Share Posted November 8, 2009 I dont know much about porting yet but you have 5 degrees more on your transfers and exhaust than I have right now on my Trinity mx ported jugs if that helps any.
