I've been thinking on why does the cam chain wear so fast on this motor.... looking at photos of things it looks to me the valve springs are large heavy wire type, also dual springs, this motor doesn't rev high enough to need a really stiff spring and it has a very mild cam.

You think that the springs are just way over kill and its putting to much strain on the chain ??

I'd like to see someone test the spring rate of these, maybe able to loose the inner spring to lighten the load...

I know On my Kawasaki ZRX the chain is on the very outside left, the lower cam chain sprocket gets cover'd up to 3" deep in oil and gets oil'd from the top at the cams....
Some guys get up to 100,000 miles out of'm..

I'll just replace mine on the Savage every 15,000 miles as I can get them for $50 each...
