    The Viking's CVT drain plug is a little difficult to access. A 3/8" OD barb and some 3/8" vinyl tubing is all you need to relocate the drain to a more convenient location. The stock plug can be reused. The additional benefit to ease of access is you can easily see if there's any water in your CVT housing from a quick glance at the vinyl tubing. I zip tied mine to the steel brake line to keep it from rubbing against the rear disc brake or suspension components.







    Maybe someone can explain the logic behind Yamaha's muffler heat shield, but I fail to see it. The stock heat shield is open towards the area right behind the driver's side cavity, right where your stock CVT air intake is. It seems to me the stock CVT system would suck hot air off the exhaust, especially at low speeds where cooling is most critical. I made a block off plate for mine:

    Brilliant idea for your cvt drain.
    After sucking in water once due to my cvt intake becoming discounted by it self from a loosened hose clamp it was a pain to access and to physically pull the plug out.
    Definitely going to copy your idea. Awesome

    Did this mod today. I have never accessed the plug. I can't imagine trying to drain the CVT trailside w/out this drain extension. Thanks to OP for sharing.

    So, by looking at this, I am thinking that I need to remove the side panel to access this. Any tricks on removing this panel? I removed the 3 plastic screw/rivet do hickies. and the two bolts on the back wheel well area but still feels attached. Am I missing something?

    I can't remember if the seat pan needs to come out too or not. I do remember that it is a little fickle to get out. You have to slide it toward the front of the machine while prying the bottom end by the rear wheel out quite a bit at the same time.
