GPZ500s rocker arm o-ring replacement

[Bomberman]

Hi,

My GPZ has developed the tiniest leak from the left front rocker arm shaft. Not really a problem atm but obviously a warning sign. Is it possible to replace the o-ring without having the rocker cover off?
I'm assuming not and that if I drew the arm out everything falls about inside there Also worried about affecting the cam chain tension etc...

Advice anyone?

If you mean the allen headed plug just take it out, replace seal and refit.

Yeah, four of them, 8mm allen heads.

Simple as eh? Excellent, get that sorted on the weekend. Cheers
