Yeah the new springs the kits come with are stronger. Your clutch may be out of adjustment since your old springs have probably weakined over time. They would have had to adjust to make up for this. So if you want your stronger springs in you would need to adjust it back to the stock setting on your adjuster that would be right on top of the motor. The stronger springs will just make your clutch grip a little better because they make the plates go togeather harder when you let out the clutch all the way to reduce slipping.
