Cb125s stuck two piece head

[rowdyrandy]

I've got an 82' cb125s with a two piece head - doing a rebuild and can't for the life of me get the two halves to separate. Won't budge at all and I've already chipped a fin wacking the crap out of it (with a rubber mallet) - any ideas of what I could soak this in or advice from anyone who's encountered the same? Thanks in advance guys

You sure you got all the bolts out? Honda is notorious for hiding one or two too keep things interesting.

There are 5 Bolts, 4 nuts holding it on according to the fiche.

Not OP but... I'm trying to take apart my '74 CB125S at the moment and can't get the head off. I know mine is the 1 piece head but the bolts are near identical. Looks like I might have missed one. Thanks!

Edit: I missed the bolt marked what looks like 11 in your picture. Everything came off no problems with it removed!
