Or you got the wrong chain. You need to take the top off and check.

I'm using the same chain that has been there the whole time and what really confuses me is how this can happen at this late stage. Fiddling with the clutch and all that, should have no impact on the chain as far as I can tell.

I probably have to take the top off, but I really, really would like to understand how this could happen.

I suppose I need to have the engine out of the frame again, in order to take the top off?

I don't know what that would prove though. Either something is binding at the crank shaft, or at the cam shaft. (Stating the obvious)

There is no slack, period.
turning it now may get the teeth to engage with the chain, but I'd be uncertain if it was timed right.

I wouldn't pull the motor! you just need to take the top off so you can look at the gear and chain on the cam.Either the chain is not properly seated on the cam shaft gear or the drive gear on the crank shaft, It's the only thing that would explain the chain being that tight.Instead of plastic to lock the gears when working on the clutch it may have been better to use aluminum.At this point I don't think rotating the motor backward will help,but if it did allow the chain to mesh with the gears the timing might still be off.

Just a thought, and hopefully not an evil one.
Is there ANY chance you put the cam shaft in with the piston at BOTTOM dead center, instead of TOP dead center?
Can't be.. would have shown up when you were adjusting the valves.

As Versys says, and as much as I wouldn't wish it on anybody, I think you better open up the top and take a look at that chain all around.

You can, but take the starter out. The one way starter clutch will engage and you can bust out the mounting or crack the case.

Pressing left side of chain: Pressing right side of chain: I'd still take off the top, you need to inspect.

I went in for the day, to grab a cold beer and read a good book. Needed a break.

No matter what, I now need the top off to check timing etc., so will start on that day after tomorrow as we will have guests all day tomorrow.

I cannot thank you all enough for the responses and help. I will let you know what I run into going back in.

If the cam is on the backside of a lobe and a valve is closing - the valve springs can be trying to rotate the camshaft forward and it is pulling on the cam chain.

If it was turning before the clutch work, most likely it is something to do with the clutch work. Common sense says undo the last thing you did and check.

And pay attention to the oil pump drive gear. It's easier to get backwards than the oil filter.
