My clutch is strong and grabs great. Back when I joined this forum I did a post about a diy no slip clutch. Stacked 2 clutch plates together with a bigger flowernut.
It allows for more tesnsion on the spring and gives you more suface weight when being pressed. The second plate also absobs some of the heat keeping the lower plate cooler. Been running it 3 or so years now
The modded clutch will need the right adjusting. It took me a bit to find it but their is a sweet spot where it grabs like a bear claw. clutch arm, flowernut, and main spring. Mine hasnt sliped a day yet even with all the added power
