No i dont think he is member at TYforums, but he has some pictures at vintagevmax at my project.
Yes he is from Norway, have talked with him earlier this Winter. I will start with my srx 500 restoration at the summer 2008. Have almost all original parts now, just missing the windshield(OEM). Jon Bertolino have been excellent helpfull to me.
Jon is a great guy. I´ve been intouch with him time to time. He has some of the greatest Yamaha snowmobiles ever made on his garage, especially the Bender ones.
Post some pics or a link to the vintagevmax.com thread. You have one great sled on your hands there.
