I would be interested in seeing...or rather hearing what this does for a CFMoto but will remain skeptical until someone does it as the CFMoto has lighter springs then most others and only has 400-500RPMs of stall....at least mine does. From experience I know a few grams of weight can make hundreds of rpm s difference in stall for example, my Kawasaki, with only a change from 4-58 gram flyweights to 4-56s, it increased the stall by almost 300 rpm. That's only 6 grams to make that difference. So, increasing the shoe weight will have the same effect but in reverse. I don't know what these slugs weigh, but whatever you do you don't want anything less then a 200rpm stall for the warm-up when the loop is open or you may have shoes making contact with the drum all the time at idle making them wear faster and even more miserable to shift gears then they already are....I know you can relate to that. Sure you can put in heavier springs..but doesn't that defeat the purpose? And..doesn't all this add to that infamous "rotational mass-performance-killer" we are trying to reduce with the wet-clutch delete systems? I do see the Rhino guys swear by it and the CFMoto wet clutches do tend to wear faster ...and there is no question a heavier shoe will generate higher contact pressure at speed, it's the idle to full engagement I question with the Moto..so let's see someone do this and report back. Mine is just fine for now...lol
