  • Tusk Magnetic Drain Bolt

    Tusk Magnetic Drain Bolt

    Steen in UT

    Upgrade over stock

    Would definitely recommend grabbing these if you need a couple more buck for free shipping. Not necessary, but nice to have. I'll know how useful they are on the next oil change, but they fit perfectly. I wish it took the same wrench size as stock, but at least it's not a weird size like other Tusk items.

  • Tusk Competition Clutch Kit

    Tusk Competition Clutch Kit

    Mackenzie in NL


    Only had a couple hours but I'm not sure if it's something I've done but I find the clutch super stiff to engage when cold and it slipped like crazy on the first start up but it gradually started to grab after breaking in.

  • Tusk Clutch Kit With Heavy Duty Springs

    Tusk Clutch Kit With Heavy Duty Springs

    ronald in FL

    Good price

    Kit is a good price but doesn’t include the friction plate that mates with the aluminum pressure plate. It works ok, but wears out the pressure plate. They need to include this plate or make a steel pressure plate. I will have to get the correct one from Honda.
