Hello, Currystomper,
You're welcome to add to other posts or start new ones, as suits you best - we are not etiquette-driven around here. Sometimes your post will get more attention if you start a new one...
An interesting frame for sure, you'll certainly be up in the air, but you'll want to keep your seat height lower than 3 inches less that your inseam to insure you can handle the bike at stops and starts. You can lower the rear suspension to lower the seat a little, but you may want to get your learning done with first, because lowering the rear will increase the trail and reduce slow speed tracking - after you've learned the MBB riding style, you'll not even notice the rear height adjustment.
The stem looks like a threadless type, which is what the kit is designed to work with.
Keep us posted on your progress!
Be well,
Doug
