Ayup agreed get softer springs. oil ''will not make the clutch do this'' The sooner you get into the power band on these motors the better power you get. They make softer springs..only way is to change the springs soft= low rpm stiff= hi rpm. some say oil wt but i dont think it does that much. good luck dennis
Must be why they are made that way. Ware did you get the springs? i may not change.
