Honda CB750K bike engine oil leak problem

[garystephen2012]

I have a Honda CB750K bike which was used by dad before 15 years ago, but still its in a good condition but there is a small problem in the engine head, there is a small oil leak in the engine head which some times makes difficult to start the bike so i asked a mechanic about the issue he said it may cost a huge about to repair the head.
I have no idea whether to repair it or buy a new bike instead of it. If you have any idea about it please share it below whether its worth to repair the bike.

There are oil seals in the cylinder head that over time will have gone hard; especially as the bike has been unused for a long time and these may leak engine oil. I would take the engine out and lift the head to see whats what first. Chances are it will be a simple fix.
Good luck with it
