how tight should the camshaft chain should be?

[Jenya]

Hello,

I've installed camshaft per Clumer manual instructions and in the end noticed that the camshaft chain is extremelly tight. If I try to move the chain up and down in the middle between the chamshaft sprockets, it moves may be only a couple of millimeters. I may be imagining it, but I seem to remember that it used to have a little more free play before I took the camshafts off.  It also feels like it is harder to spin the crank as well.

I wonder if I did something wrong with the chain tensioner. I followed the instructions and used a flat screwdriver to relax the internal spring, which pulled the plunger in. I then inserted the tensioner into the head and removed the screwdriver. That, in turn, released the spring and pushed the pluger out. Because of the force of the plunger against the chain guide, the tensioner got pushed out from the surface of the head a little bit (~4mm). I then tightened the tensioner's screws, which pushed it flash against the head and created a high tension on the chain.

What I noticed is that despite the amount of force I tried to exhort ontpo the plunger before installing the tensioner, the plunger wouldn't move at all. The Clumer, however, makes it sound, like it should be moving freely when pushing on the plunger: "Push in on the plunger (B) and then release it. the spring should offer resistance when the plunger is pressed in. The plunger should move in and out with no binding".  Like I said, I wasn't able to make the plunger move, regardless of the force I was pushing it with. However, when I turn the internal spring clockwise, the plunger is pulled right into the tensioner very freely.

I have a spare tensioner that behaves exactly the same way. That makes me thing that it isn't that the tensioner is broken. Perhaps, I shouldn't have released the internal spring before tightening the tensioner's bolts, and hence preventing it from being pushed out from the surface of the head.

Any advice is very appreciated. I feel I am so close to getting the bike back on the road,
