Recently took of the head to adjust valves and do some extra work. I put it back on and the bike is struggling to start and it sounds heaps louder, what are the possible issues?

I’m guessing that the valve clearances are wrong, the intake is not properly seated or an exhaust leak.

I adjusted my valves about 4 months ago in December. I have now driven approximately 3800 km and I have bad compression again.

Is there anything to do to fix valves going out of spec so fast. As far as I’m aware they should last 7500+ km.
