To add to my post and Frank's post. If I had the mechanical skills, I probably would go with the complete Wiseco kit and do it myself. BUT, I don't feel comfortable doing it. D&D including all labor, parts, and dyno runs, cost me right at $1250. They are my Triumph dealer and the nearest place there are people I trust to do the work, so I went with their complete kit. They don't do the sleeves anymore.
If you do it yourself, you still have to have your barrels bored and the sleeves put in by a machine shop. OR, you could pay to swap your barrels for a set from D&D already done with a complete kit.
Whichever route you go, I guarantee you will love the performance results. At my 5,000 miles per year, it would be a long time before either BB kit could be a problem. Whether it lasts 60,000 miles or 100,000 miles probably won't make any difference to the more mechanically inclined. Like the Nike ad, just do it!
