December, 2013: Good news! Harbor Freight has started selling the motorcycle attachment for their tire changing stand again!
If you've already bought your Harbor Freight motorcycle tire changing stand, you've probably noticed the rim-grabbing jaws are made of powdercoated steel. That's fine for the crusty steel rims from your '82 Pontiac, but what about your beautiful, chromed/painted alloy motorcycle wheels? In an effort to protect their rims, users have tried lining those jaws with all kinds of things: electrical tape, duct tape, sliced-up rubber hose, and plastic dip, to name a few items. But unless you're careful about securing this stuff, it can slip out of place, leaving you with damaged rims.
The solution? Mojoblocks:
With a set of Mojoblocks, you can easily retrofit your Harbor Freight tire-changing stand so that it will grip your rims without scratching them. The cutout in each Mojoblock is wide enough to accommodate even the tubeless wire-spoke wheels from BMW's GS-series bikes.
The Mojoblock package includes three Mojoblocks, three Nylock nuts and three bolts - one for each jaw on your Harbor Freight tire changer. To install them, you just need to drill a bolt hole in each jaw on your Harbor Freight tire-changing stand, and bolt the blocks in place. Click here to view the installation manual.
To my knowledge, there are three different jaw styles on Harbor Freight tire changers. If you have not already purchased your Harbor Freight tire changer, I recommend doing so before you buy the Mojoblocks. Examine the rim-grabbing jaws on your changer and compare them to this chart:
The price is $30, and that includes postage to anywhere in the 48 lower United States. If you need it shipped somewhere else, email me and we’ll work something out.
I currently have a limited quantity of Mojoblocks ready to ship! Please email me to confirm availability of the type you need and receive payment instructions.

If you haven't already got one, you might also be interested in a Mojolever.
