    Have you tried running a string around the "route" of the belt & getting a measurement from that? Might be the easiest route if nobody knows the actual length right off hand.

    Yep thats what you are goona have to do most likely for the accessory belt (string method) to get you close atleast. The actual blower belt, it would help if you provided the diameter or cog teeth numbers for the blower pulley and the crank pulley. Or you can call ASP www.aspracing.com and they can help you with sizing the belt.

    You need a 1440 or a 1392. I think a 1392 may be the ticket with the small cogs. I run a 1440 with a 27/77 on my YSi.

    Get them from Vortech or ASP.
