Spring Question

[The Goat]

So I'm doing my annual clutch inspection/service on my '02 800 Edge, and one of the things I'm going to replace is my primary spring. My jetting is right where I want it, and I'm about 100-200 rpm shy of where I want to be, so I'm thinking a spring with a higher compressed rate. Am I right? I like where it engages, so I believe I'm only wanting to change the 1.25" rate. I'm kinda new to clutch tuning, so let me know if I'm completely off here. Anyone have any suggestions for a new spring that'll help me accomplish this?

Current primary setup:
10-60 weights
black spring with green mark

completely stock engine
9,000' - 10,500' elevation

Thanks!

Polaris Almond round or save some cash and buy the SLP Blue/pink.

Is the SLP Blue/Pink supposed to give me higher top rpm than the one I've got? If so, any guess on how much higher?

Thanks guys.

It will give you that extra 1-200 that you are looking for.

Dropping a tooth on your large chaincase sprocket will also give you higher rpm and better hill climbing power, without the hassle of buying and testing out a bunch of springs. The chaincase gearing was for Minnesota wheat field riders, though.

Thanks for the input. Turns out the SLP blue/pink spring has the same compressed rating as my black/green spring, so it won't do anything for my top end, only the engagement. I ride at around 10,000' so I'm going to drop a size in my weights (down from 10-60 to 10-58) and see if that does the trick.

That's not true. Go search through the clutching section and read about springs. Also notice that SLP rates their springs at slightly different measurements than the stock springs are rated.

Or open up Excel and plot a straight line graph of the two springs and you'll see that at any given clutch compression the blue/pink has more force.

Not to mention the black/green is a horrible spring and is likely sacked out some.

I won't say that you won't have to drop weights to 58s, but seriously, try either the blue/pink or the Polaris almond, I think you'll be happy with it and it will give you want you are looking for.
