Action Update:
I have been riding the bike for about 1.5 years since the conversion, and I have logged around 4,000 miles in that time. Most of the riding has been on local country roads, and I have been on one group ride of 120 miles, and made a couple of Dragon Trips with the bike. I am not sure how many miles we rode on the Dragon Trip last year - but this year MM, Oldfellor and I rode 250 miles in the Lynchburg area, and MM and repeated the 250 miles each day in the 2 days we rode together in the Dragon and Waynesville rides.....and for me that included 6 runs up and down the Tail of the Dragon at a fairly aggressive pace (aggressive for me). I did have a group of Sport bikes and Motards with slicks that seemed to be doing twice my speed. I believe I rode about 900 miles total during those 4 days.
I did find at the end of the Dragon Trip that my rear wheel spokes had an issue - I had 4 broken spokes. After a little research I found that I most likely did not have the spokes tight enough, and it is common to break spokes when they are not torqued tightly. I bought replacement spokes and a spoke torque wrench, and I have the wheel ready to go again. It may be good that we had wet roads for a some of the riding, as I may have broken more spokes with more faster riding.....with potentially scary results. I now believe that for an amateur wheel builder like me, that the spoke torque wrench is a necessity.
I installed Pirelli Sport Demons on the bike during the conversion. When I took the tire off to work on the wheel, I dediced that although there is some tread left, there is not enough to justify putting it back on. I am surprised that I have worn so much tread off in just 4,000 miles. I don't do a lot of heavy acceleration and I try to corner aggressively - and yet I have worn the center tread down until only about 1/3rd of the original depth remains...the flat center is about 1/2 the tire width. The photo doesn't really show the flat spot like it looks in person. I would expect that if I left it on until bald, I would have gotten about 5,000 miles from it. The Pirelli Sport Demon is on the right in the following photo. It is supposed to be a Sport Touring Tire, and note even a soft SPORT rated tire.
I decided to go with a Bridgestone Battlax BT-45 Sport Touring tire and try it out. This tire has a harder tread compound in the center for extended mileage with the sides being a softer compound for grip. Hopefullyl this will even out the tire wear and keep the tire from wearing out the center too quickly.
This post update is not only to provide a warning to those who have built their own wheels to check their spokes frequently - but also as a way for me to chronicle a few things. The total mileage on the bike is 7,365 miles. The miles since the Cafe' Conversion and miles on the Pirelli Sport Demons is 4,000, the mileage since the engine upgrades (cam, Wiseco 95mm, Mikuni VM36) is 6,000. The bike averages around 54 mpg, and top speed to date is 101.1 mph.
