I just finished installing my KD 700HO (single) upgrade, and I documented the process on my website: http://www.mech.ubc.ca/~mabauman/kershaw700HO.html Those of you already familiar with the KD system will find nothing wildly novel here, but I hope that it can provide some info to those who are interested but aren't sure on the details.

As far as my impressions go, the new motor rocks! At 16.8V it's definitely faster and has more torque than stock. I'm very pleased with the whole thing. If you think there's anything missing from the walkthrough, just post it here and I'll add it to the page.
