    Maybe EngineerMike can enlighten us. I didn't know crower made them. It says special grind so maybe it was a custom order.

    If I read the spec sheet in the ebay add right it should have a lumpy idle with that amount of lift.
    I think I heard these cams are regrinds

    YES..... that in combination with the lightened cam gear, lightened rods and lightened counter balancer lightens the rotating mass of the engine at lets it rev faster......... BET! so u would think a high performace cam would be lightened in anticipation of use with other high performace parts!PERIOD!

    i can't speak for the rotax racing cams... but every single other cam floating around from all different sources are regrinds. which according to cam companies should not be a deterrent, cams have been getting welded and grinded for longer than most of us been alive and they claim them to be stronger and prone to LESS wear due to the new welded material being harder

    here's a ski i used to have that had a little bit of a lumpy idle ... quite a bit more lift than stock

    The lightening of the cam rotating parts is more about making it reliable to rev than about gaining performance IMO, unless you are talking crank/flywheel and balance shaft.
    gotta love that idle!

    funny thing with crower cams is they recommend using mineral oil and not synthetics, hmmmmm

    exactly... IN COMBINATION.. so taking everything stock and throwing a lighter cam in there with all stock rods and postons and crank and CB shaft.. IMO, jack shit to be had from a cam unless u go balls out on the whole motor lightening...

    do it all, or dont bother ranting and raving about a lighter part bc in reality throwing one lighter part in the mix ur not gonna feel on the seat nor on the GPS

    get into the reciprocating assembly for gains u'll feel and see... i'm not a proponent of throwing a couple lighter spinning parts in the head that aren't reciprocating and preaching about gains.. they just arent there.. IMO
