Need to remove rocker shafts from cb60

So I’m doing a head gasket on my g11 figured I would port and polish it while I was at it but can’t for the life of me figure out how to get the rocker shafts out when’s for a search couldn’t find anything read the workshop manual which is helpful for anything else you want to do but didn’t help me as it list a specific tool i don’t have has anyone rigged something up that has worked for them

To remove the rocker arms, you will need to remove the distributor and the housing that turns it 90 degrees from the cam. Then loosen all the rocker assembly. The rocker arms wool well come out with a bit of a yank.
