cam questions

Cam Motion recommends G2's (for a 16 valve 1100 motor) if you're planning to use the stock rocker arms. Any more radical and you're going to need hardened rockers which really jacks up the cost. An 1168 big bore kit is cheaper even with the machine work factored in.

Not true as I run up to .380 cams on stock rockers with NO problems. I put G4s & G7s on STOCK rockers all the time! It is the SPRING pressure that makes the biggest difference on the rocker life. Take it for what it's worth from an engine builder. Ray.

Hey Ray, out of curiosity, @ what lift would you need to shorten the valve guides using CM cams. My bike has g21's installed from PO and was wondering if the guides would have been shortened?

I agree with ray 100%

The rule on 16 valvers is pretty much .370 & over you use shorter guides. Ray.
