I just got done making that same engine swap. It's a piece of cake. The only brackets you'll need to fabricate are the front motor mounts. I made head stay mounts and took them off, more vibration than I could stand. I just got my FTZ Super Fat drag pipe on and recommend going that direction if you can spare $310. I plan on extending the swingarm 12" and going hunting for stroked Banshees. If you have any "tricks" you've come up with, let me know! The vibration is bad, but I think I can stand it for 100 yards at a time!
