Someone suggested to me to put a "Almond round spring" and 66 grm wieghts in my 2001 800 xc. I already have a silver spring in my secondary.Does this sound right ? Any ideas?

Their talkin primary, almond round *or almond square I definately would try and if it doesnt rpm go to 64 gram weights, if the guy seems to know his stuff try the heavy weights first. Your in the right direction.

a proper running 8 should easily pull 66,s

thanks for the help guys, hope it works
