    Has anyone ordered carb diaphragms from JBM Industries? Are they good quality? And if so, does anyone know if they carry any diaphragms that will fit a yx600 Radian? I was looking around their website but it is quite hard to navigate. Looks like its from 2004 or something.

    Several members have, though I haven't. Reviews are good overall, but some have found the diaphragms to harden after a few years of use.

    The Radian is an XJ550 Maxim with different clothes on. Get diaphragms for a 550.

    JBM diaphragms fit like a glove. The bike is running phenomenally. Cutting off the big metal washers on the carb pistons was a bit of a hassle tho.

    I was just thinking I should go ahead and replace mine after all these years... I see this post about JBM Industries, and find out they're 14 minutes from my house!!!

    Jbm make it very clear to never use fuel system cleaner with the diaphragms.
    Good thing I read that after wondering why mine got all sloppy.
    Also a good thing they are cheap!
    Bought more and have learnt that lesson.
