koso clutch spring

How often do you guys change your koso clutch spring

Torque spring changes are something that are handled differently by most.

I have heard of changes after every race or every few races....some once a season.

The sping does lose preformance after use and interaction with heat.

So you should try to tune with this in mind.....Rollers that are just right on a cold spring may be a little too heavier on a long race where heat can become a factor.

You can also use and RPM guage to see where your quad shifts between low and high when the spring is new.....If you notice that it is shifting to high gear sooner then your spring could be suffering from fatigue and/or is either broken in to where it will perform at or need replacing.

Koso makes very good springs though
