I have completed front shock Evol upgrade. The MBRP trail can is installed. Ten pounds of dead weight removed . 144 studs installed. My airbox has been modified and installed . I would like to thank Allen Ulmer for his guidance and customer service in helping me thru my first clutch install and a ulmer flashed pc5 . The sled sounds great and appears to gain rpm at a much higher rate . Only rear shocks to go thinking about fox with Hygear dual rate springs . Cannot wait to see my ski doodle buddies on the snow . This viper has turned into one pissed off snake !
