    Swing Arm Buddy Chain Adjuster Bolt Repair Kit

    Christopher in CO

    Just get a new swingarm.

    Tried using this for a few months after a seized bolt... No matter how many times I tightened it, my chain kept falling off. Don't even bother with this. Found a swingarm on ebay for 70 bucks... 2001 KTM SX

  • Motion Pro Belt Tension Gauge

    Motion Pro Belt Tension Gauge

    Must have to Check Belts

    I've been working on Harleys for over 5 years and when you are doing a service on them you have to check the drive belt deflection. I would rather use one of these and get the belt precise than using the "feel" method. I've never been good with that and would rather use this to let me know exactly what the deflection is. If working on your own Harley, you should have one of these in your tool box. I'd buy another one if mine ever broke.

    Pro-Taper Rear Aluminum Sprocket

    BRYAN in NM

    Wearing faster than I expected

    Compared to the Tag sprockets I've used, this one's wearing faster. I'll probably use something else next time. Bike is a KX144.

  • Liquid Performance Chain Lube

    Liquid Performance Chain Lube

    Mark in NH

    Was worth the money

    Got this on sale so it was worth it. I wouldn't use it on a regular basis, it's kind of thin and I'm not sure it will work as well as one of the big name brands.
