an "isovibe" is exactly what the name implies lol. Its a handlebar riser block that incorperates rubber bushings to deaden some of the vibration of the sled that is transmitted through the handlebars. they also take the edge off big hits. As for skis, almost everyone here runs C&A razors. SlP powder pros are also common. Clutch kits can do a bunch of things for performance. They can change the maximum rpm of your motor to best suit its powerband, they usually make for harder upshifts, and can tune your available power for a variety of riding styles. There is alot of talk here on many different clutch kits and feedback on just about all of them. do a search on the forum and look around :div20:
