Since the first one rolled off the assembly line, the KZ1300 has struggled to “keep its cool” under anything less than favorable conditions. David Ewing, the founder of KZ1300.com and the man responsible for bringing international recognition to the site, once did a Muzzy fan upgrade for the big six. After joining this site a few months ago, I researched (what I thought) were all the tech articles, but was unable to find any detailed information on the conversion. I am certain that the process I used is not identical to the one he used. I am equally certain there are most likely numerous other ways to accomplish a successful installation. The following process worked best for me with a minimal investment of time and money and yielded satisfactory results. Hopefully, I have provided an adequate explanation of the process, along with pictures, which should make it a fairly straightforward procedure for anyone wanting to cool down the big behemoth. Feel free to contact me with any questions or suggestions that others might use in the future to make it a still simpler process.
4 Blade stock fan and the new 6 blade Muzzy fan
Notice: This particular fan (Model HT-H8) is still available through Muzzy for $39.95 and is designed to fit every 1300 model EXCEPT the KZ.
With a few modifications, this becomes an easy install for the KZ.

After removing the 8mm nut and two washers, you'll need to remove the center aluminum hub from the stock fan blade. Don't worry about salvaging the old fan....you're done with it.
Notice you not only pick up two additional blades, but they appear to be at least 25% to 30% larger than the stock blades.
Using an arbor press, remove the center hub from the stock fan. If a press is not available, using an appropriately sized drift or socket, (with a hammer), drive the hub from the fan. Don't worry about salvaging the stock fan...... you're done with it.
