Default heavy vs soft clutch spring ??

General question

What on track differences would you see from a standard clutch spring with heavy tension on clutch nut versus very stiff spring with light tension on clutch nut.


standard mrx4x spring versus orion crf spring.

I think one benefit would be the spring being able to hold it's tension longer, this keeping the clutch pressure constant over a longer period of time. With the longer mains and the heat generated by the clutch engaging and disengaging, a spring will eventually soften and loose tension. I know most people at my track with the MTx4 jump straight to the super hard MSR spring before they even build it. Haven't tried the Orion spring yet though.

But I could be wrong....

I had the chance to run the orion spring and it is a good spring. Hits like a ton of rocks when setup correctly. Very good for high grip conditions. I like the softer springs for when tracks are loose or low grip. Sometimes its hard to get all the power to the ground. Its hard to answer the question you asked. You have to take into account track conditions and what shoe you were running?

For qualifiying, I like to run a softer spring tightend down with a soft shoe, but in the mains, a harder spring and hard shoe.. thats just me. others, run the same all the time
Am I going back racing?...Hmmm.. Not anytime soon... But soon enough.

Harder spring = more explosive. Try it and you will not go back.
