Ditto, MRP....junk.
Since your kinroad already has a CVT transmission, changing out the clutch is doubtfully gonna increase your top speed, Top speed is controlled by the variator, and how high up on the pulley the belt can pull. If it is already at it's max height, then you are getting all the gear mutiplication available, and your top speed is set, until you either change some final gearing,(sprockets) or increase the tire size. Either of these is going to put more load on the engine, and may then require clutch and variator mods to return the belt to full extension. In some cases, you will even need to mod the engine for more power to get the belt back up on the variator. Just depends on the tire size, and or sprockets you choose.
A clutch change CAN allow you some adjustability though, with different "shoe" or pad > pillow springs. And a slightly stiffer torque spring can be beneficial as well. IF you are not currently getting the full belt extension, sometimes a stiffer torque spring can allow engagement at a higher RPM, getting the engine in the torque band, before it starts loading, which can allow full belt extension. The CVT has quite a few variables working together, and you can go from a higher speed(top end) to a lower speed, but with stump pulling power, just by changing some weights, and or springs.
But expecting a MAJOR difference, simply by changing out the clutch, ain't gonna happen, unless your present clutch is completely worn out, and slipping throughout it's RPM range.
