i started this thread to see if it would help me change my mind from semi to full and it did .. Motul 7100 is what i am gonna get ...I went to Amsoil after the initial break-in. The bike shifted noticeably easier. I thought it was BS until I actually tried the oil myself. Amsoil has gotten pretty expensive up here in Canada so last fall I did some reading and am going to give Motul synthetic a try for the upcoming season. I changed the oil in the bike last fall before putting it away for the winter. The Motul oil is red in color which surprised me! It should make reading the dipstick a lot easier. The oil-check procedure is a big enough PITA without having to look for nice clean clear oil on the dipstick!
