Ran this on my old H1 for ages but I've since upgraded to more modern forks and wheels and don't really see needing it any more. On my H1 this was a BIG improvement on handling especially combined with taller shocks. This is a Moo inspired mod. Do a search on here. I'm sure there's info on it. It's simply an 18" rear rim laced to a stock H1 front hub. It a good decent wheel but NOT suitable for a flawless bike. I got it from Cody years ago. Great function, decent form. Has a few tire iron marks and the spokes are not flawless. But it's straight as an arrow, handles great and come with a really good low mileage Bridgestone BT45 tire and perfect low mileage bearings and speedo drive. $150 plus actual shipping costs. Was in a hurry tonight but would be happy to take some daylight pics or answer any other questions.
Can I have 24 hour dibbs so I can sleep on it? 
JaMoo is the real expert on this (i think he more or less invented it) but It basically drops the front end and alters your geometry to quicken up your steering. I wnt to Deals Gap one year on a 19 and cam back the next on the 18 and it was a huge difference. Had all the other usual mods (tapered bearings, bronze bushings etc) and taller 13.5" rear shocks and it was night and day. Not quite like my RD400 but a lot closer.
