Tripled my compression upon assebly?

Hey Forum, (I'm Danish so might not have the best grammar)
I just took my newly purchased TE610 95' apart to locate a very strange noise coming from a unknown source inside the engine. My theory (as read online) was the camshaft or cam chain tensioner was the source. I took the top piece off and found out that the previous owner didn't have had the camwheel bolted on tight enough (it was actually loose). Happy that I have found the error that probably was the source of the noise, I put the bike back together, and that was when I found a new problem. I was unable to use the kickstarter because the compression was at least twice as hard as before, I was like kickstarting a two-stroke. I quickly gave up because it was to hard and I never got the bike running. My question now is; what have I done wrong? I haven't touched the timing and never disassembled the camchain or anything? I have had the top piece off, and tightened the bolts on the camwheel. Put it back together and now the damn thing is to hard to kickstart, and its pure compression, because I can put pressure on the kickstarter and make it come over the TDC, as I would do on a two stroke.

I haven't touched the timing but I didn't pay any attention to where the the timing was when I put the top piece back on? Is that the problem?

I really am lost on this one guys, I appreciate all the help I can get.

This was the only piece I had off and tightened the bolts on the camwheel

Not sure exacly but it sounds like there is an auto-decompression that is not working. Cam.

EDIT: Sorry, response was not correct.

Take out the spark plug and see if it turns over easy...If not...back off and reinstall the cam chain tensioner.

The cam chain may be super tight now that you tightened the sprocket.

May also want to check the water pump impeller. Some people have noted when reinstalling it, the impeller actually was making contact with the cover causing damage.

how do you set the timing i feel as if my timing might be out as well

Timing is as per the workshop manual, it might be similar to my 630, but I'll let someone with a 610 chime in on that. However, you basically just have to align certain markings on the cam sprockets (both intake and exhaust) with certain locations (or other markings) on the cylinder head. This is done with the piston at a certain position in the sleeve, which is normally with the piston at Top Dead Centre (TDC).

Sounds like cam timing and the piston is pushing up against the valves
