http://www.valkyrieforum.com/bbs/index.php/topic,40130.0.html I just did this last week or so. It's your bike and all but I would not go the freeze plug method. IMHO, the two front plug locations are simply too difficult to get a good position/angle on. Plus I've read on this forum of an installation causing some expensive repairs due to cracked heads.
The Redeye kit is great and I highly reccomend it.
All the best,
Mark
