I am replacing the Camshaft on a 2005 650 h1 , The Cam Lobes were chipped and cracked and pieces were missing looks like it got to hot and brittle. My question is Are there other Models and sizes I can Cross Reference this Camshaft with? I am finding Camshafts but they super expensive and i can't find full Kits with gaskets . Anyone have Suggestions for finding a good Bang for your Buck? Or are there other Models that use the same Cam I can find it for that would be cheaper? Need like a Cross Reference Guide. Any Help or Suggestions would be greatly appreciated.
