1988 Honda Fourtrax 300 Cam Plug Replacement Procedure

Hello,

The Black cam plug on the Right Side of the Head on my machine is pretty well tosted. It’s leaking quite a bit of oil now.

How does this plug get replaced?

Does the entire Cam cover need to come off ? or can it Just be replaced by taking it out & reinstalling from the side?

Thanks for Any info, links, tips and help!
