    torque specs for cam and head

    i was wonder what the torque specs were for the head studs and the cam sprocket bolts? it will have the hotcams in it but i assume they are the same cam torque specs. i don't know if they changed much but it is a 2003 if that matters.

    also, i don't know if anyone has had a problem but we cracked the exhaust camshaft holder while torquing the head cover on. we had it set to 10 ft-lbs and we didn't even get it that tight and that cam holder cracked. i don't know if this is a common problem or if we just had some bad luck.

    is there a cheap place to order suzuki parts online? something like service honda, but for suzuki's? the quicker the shipping the better too. thanks again

    See the part that says "Camshaft journal holder bolt"... 7ft/lbs like I said.

    I can pull my head down and switch cams in my sleep.

    nator, i thought that torque was for the 8 bolts on top of the head that hold the camshaft holders down and not for the cam sprocket?
