My situation concerns the fact that I have a SL350K2 rolling frame and a CL350 engine. Now, I am aware that the SL head has different porting along with a different cam for more torque (also has non-CV carbs). My questions are : #1 Would getting an SL cam and putting it in the CL head be worth the effort? #2 Or would the SL head be needed to make it worth the effort? I can get the cam for $20. This bike will be built for messing around in the woods (up and down hills too) and never see any "road time", while I have it.
