I have a few newer sleds but still love riding my old Yamahas. I have 2 SS440s (a red one my dad had since 1980, and a blue one I got free from my friend), well I rebuilt the blue one and clutched it, and man that thing rips. I would bet that it keeps up with newer trail sleds in a drag, it easily runs over 80mph. What is the hp of one of these sleds? I was thinking about setting it up for ice drags next year as a low money project since I spend enough money keeping my other sleds going. thanks alot.
