I tried to tap it back after loosening the nut and unwedging the bolt. It moved a little bit but not enough, I was hitting it hard though. Still there is more than half a mm difference. I checked out the pics I made when I assembled the head, can`t see any obvious misalingment. I wonder I should take off the head cover and loosen the big nut to deliberate the other half of the camshaft. Is that doable leaving the motor in the frame?

With this type of problem there isn't a way other than to remove the engine and get the top open and work on the cams.
\Are those cams Race Grind?. . ................lm

Sounds really bad... Next plan is to take off the right side cover and support the right side cam when hitting the left side. Those cams should be standard cams taken from a donor Scrambler, I don`t think they had been modified. What makes you think that?

Did you drive the outer of the bearing or the cam end?
When you hit the left side the right side will have the bearing driven to the right side cover.
The profile and side view of the cams in the pic show what may be modified cams. .............................lm

I drove both. I assume that when I hit the left side the right side bearing hits the right cover which is aluminum and therefore it is more soft. Therefore if I support the right cam with a metal hammer and hit the left side, I have a better chance to shorten the cam because I can exert higher force on the cam (it does not recoil from the right cover). Just a thought, I`ll give it a shot.

What you are saying about the cams is very interesting. How can I figure if they are racing cams? How would that affect the otherwise stock engine?

Just noticed your tank badge is in backwards. Sorry, not relevant to your current issue, just an observation. 😊
