CB500 K1 rocker cover woes

<< < (3/5) > >>

Kai.chris:
Not sure how to proceed now. Closer inspection of the cam, rockers and rocker pins shows worn pins where the rocker rocks as mentioned by Seabeowner.
The knock on effect looks like a ruined cam and rockers wearing on one side.
One cam lobe has a crack near the edge, it looks like the other side of same lobe had the same issue and somebody has taken a grinder to it. All lobes have uneven wear and pitting to some degree.
I was going to send the cam to Newman cams but without new pins(unavailable) and rockers (£22 a pop) there doesn't seem much point in re-profiling the cam anyway.
Where should I go from here? new head, cam and cover out of the question.

Bryanj:
The small pitting is relatively common and wont hurt as the rocker runs on the middle, the rough edge howeverdoes look bad.

Now the head, cam and cover are the same on all 500 and 550 engines, i may have a spare cam and bare head but not a spare cover at the moment

Kai.chris:
Thanks Bryan.
My cylinder head is currently with a local specialist having the valves cut in, won’t have started it yet.
Would it be unwise to say throw your spare cam on my cylinder head, or are
your cam and head matched? How much does it really matter for a bit of gentle back lane riding. 
I’ve managed to source 3 of the 4 rocker pins NOS but they won’t be cheap.
Am I overthinking it all, tempted just to knock that rough piece off the cam and throw it back together. £2k in parts and now this, the gift that just keeps on giving  ::)

Bryanj:
I can find you a cam, pm me and i will work out how much, head, cam and camcover are all made seperately so not necessary to keep together, secialy for a low mileage use gentle rider, full nutter racemobile different!

Oddjob:
If you’ve found 3 of the 4 rocker shafts nos you’re doing extremely well. Are you sure they are the pinned type though? Honda did the longer rocker shafts on the late 500-4 but they weren’t pinned, just long shafts with no cutouts for the locking pin. Easier to find those, which is why I ask.

I was looking for pinned shafts a few years ago and whilst some sites said they had them in stock they didn’t when you ordered them.
