Hi guys, I’m new here and I have the shovel head engine. And as you say when you take the cam cover off the cam comes out with it . No timing marks. I’ve been trying to get a hold of Jim for a while and no reply. You say he has an updated cam and you have the valve timing diagram? Wow! Could you help me please? It would be greatly appreciated! Thanks 😊

Hey vbiker 👋

It happens dude.. After having issues w’ my R31, I got ahold of Jin and asked him about the cam / flywheel timing.  Here is a diagram Jin sent me that will help

Position the grub screw on the flywheel straight down, then install the camshaft with the 2nd cam lobe pointing straight down
