    cogs

    Anyone have experience running cogs with a small tooth blower pulley?

    looking to run a 73 lower with a 27 upper on a ysi. I heard that anything under a 30 tooth makes it harder to keep belts on.

    Yup, under 30 makes for a tight radius for belt wrap and it tends to clean the teeth off.
