Start with the spring @ .225" and adjust from there. I have no idea if you have bolts added to the weight levers or not. Also, what is your air gap? That could be as much your problem as spring heights. Is the clutch new or used?I hve a bully 2 disk 6 red spring "adult" clutch, i need assistants in setting it so it works "correctly". Setting the springs specifically etc. Please help !
