To update others here I sent a P.M. Alley about a valve problem and adjustment and whether it was metric or sae at .004 and .005. I had asked the same question on several other sites and no reply was forthcoming. The guy is great, informative and bright. Rofl I wanna be just like him when I grow up. Im even going to tell Mrs. Newbie's Trike how good his Ice Bear is to him. ;D Thanks again Alley.
