Thats the one thing people don't understand. The crank and cam don't know where they are. Which is why you couldn't shim a modern 4 stroke as fast. They want you to install the cam at T" and the cam chain/tensioner also and torque the bolts, take a measurement, change the shim, check it out and repeat.
The very 1st one I did I laughed at myself; I thought "You idiot, the crank has nothing to do with this, leave the damn chain off!".
So I just popped the cams in as my buddy watched in horror saying I didn't follow the manual!
If you understand it, you don't have to.... Any degree of dwell or "the time the cam doesn't do chit!!" is where you adjust the valves.
A two stroke is actually very more complex as to timing of the port windows and their height, etc etc etc.
I was afraid to shim a 4 stroke 12 years ago when they came out to compete with the 2 strokes. And I realized how easy it really is.....
