The Silverwing has about 11500 miles on it, and I decided to change the belt, and plan it around changing out the rear tire. I bought the S/wing with the intention of keeping it stock, and possibly riding it down through South America and leaving it there.
My choice for rear tire was fairly limited, so I went with a Pirelli Diablo Rosso in the standard size, and it was when I realized I would be taking off the exhaust that things got a little out of hand.
I ended up installing a Malossi Variator with 24 gram rollers, Honda outer plate, because the old one had wear and I figured I might as well start with fresh parts, Malossi Kevlar Belt, Dr. Pulley slides, even though the Honda ones looked fine, Malossi clutch, which seems to have better material than the Honda clutch, malossi white contra-spring, Honda fixed driven pulley, clutch seals and o-rings, Malossi oil filter, Malossi racing final drive oil, BelRay EXS 5-40 synthetic ester oil (got a deal), various bits and pieces from Honda that had fallen off over the years, K and N Air Filter, and a Malossi exhaust. Because I don't excel at reading directions, I had removed the header pipe before realizing the Malossi exhaust is a slip on. Comparing the Malossi exhaust to the stock one, I figure it's about half the weight.
For some reason, it seemed like someone had set the bike on it's side and put as much gear oil in as possible. I removed the fill bolt and though I was draining it.
I was surprised to learn from the Honda directions that you fill the inside of the Fixed rear pulley with about 28 grams of grease, which they include, before you put on the movable pulley, pin cover, and spring. Very little is lost when you reinstall the clutch. I also figured out that you can use a tool to force compress the spring once you get the clutch onto the bike, in my case a vice grip sort of universal clutch tool, and get the belt far enough down in the clutch that you can put the front variator plate on a lot easier than tightening the bolt and and turning it over. A set of alligator jaw vice grips should also work. I got the belt into the clutch, stuck the outer plate on the variator, oiled the threads of the bolt, and hit it with my impact wrench. It's not going anywhere.
My first ride was about three miles of 45-50 mph surface street, then on to the interstate to find out what I'd done. The exhaust note from the malossi pipe is pleasant. It's not loud, but it sounds more like a motorcycle. The bike seems to accelerate a lot quicker, instead of a steady increase of speed and engine rpms, the rpms jump to about 6500 and the bike surges forward. The variator comes with 21 and 24 gram rollers, and I went with the 24 grams. Now I'm curious about difference in performance between the two roller weights.
One of the issues I had with the clutch was that it shuddered and jerked from stops when the bike got hot, and I still don't know if I fixed that yet, but I'm hoping the different materials used in the Malossi clutch will work better to keep the bell from glazing up.
I put Malossi sintered rear pads in. The stock Honda pads are also sintered, so not a big change there.
As far as top speed, I really didn't have much of a chance to see how well it performs compared to before, but I was hitting indicated 105 with ease. I removed the Tucano Urbano termoscud before starting the work, but I still have the Givi touring shield I put on for winter, and haven't had a chance to switch back to the sport screen I prefer in the Summer, and that seems to have slowed it down a little, as well as made it more susceptible to buffeting from the wind.
Overall, I'm pleased with the change in performance and sound. I haven't had a chance to really push the bike yet, but I suspect the suspension is going to need a little work to take more advantage of the performance additions.

Nice to hear from you again, Mondodemundo. Thanks for your update. We’ll be looking forward to further reports about your Malossi upgrades. It would be nice to see that rpms at what miles per hour (indicated) you report with those upgrades.
