It sounds like this addresses the Majesty's major weakness, and that is the acceleration under 30 mph is weak for sure. Slightly lighter weights would allow the engine to rev a little higher and pull harder out of the hole without raising the cruising rpm much. For best fuel economy on the highway, I have already figured that much over 60 mph or over 6000 rpm really eats into the economy. Once the variator has spun out above about 65-70 mph, the final gearing is the same, so what we are talking about here is midrange anyway. If you ever ride two-up and you and your SO add up to significant weight like my wife and I do, then the extra oomph off the line would be welcome. One comment indicated fuel economy was better after this mod??? If that is the case, I would be really surprised. I believe Yamaha would have tweaked the stock setup for the best economy/performance tradeoff right out of the box, but the proof is in the trying. I may give that a shot and do it when I have to replace the belt the first time. I don't enjoy doing the mechanical work enough to make those kinds of changes unless I am already in there for another reason. Then we can kill two birds with one stone. At the rate I am going, that will be next year sometime. I only have a little over 2000 miles on it after buying it in mid-May. I'll am putting about a 1k miles per month on it, which will drop some in the winter. But not to hijack the thread, I think making the change when you're doing other maintenance in the same part of the bike makes the most sense. I do have one question...can the lighter rollers be bought through Yamaha? Or is there another source we have to use?
Cheers and no gears!
