CB750F2 .... silk purse from a sows ear.
Bryanj:
Dont know what trigger would say but i rebuilt many with worse journals way back when and they were OK. By the way the cam does not have to be in a specific position to undo or tighten the sproket bolts, you can turn the engine between bolts but before you replace followers and pivots
SumpMagnet:
Thanks Trigger :)
I will definitely be needing new o-rings.....and new pucks. Were those originally rubber? I really can't tell.
Plastigauge ..... I know of it....but have never used it. So as long as the clearances are OK, then the carriers are fine. I was worried about hte state of the surfaces on the lower half of the carrier. The caps are perfect. If those are OK, then I will re-use them.
As far as the caps go...I was worried someone had already swapped them about. The L and R marks etched in them just seemed the wrong way round. I was taught at an early age that what wears together stays together. But what do you do if it's not where it should be? Is it better to leave as is..... I probably will. Could well be I am over worrying :)
I am also going to need a good gasket set. Instant gasket is not something I approve of where it isn't designed to be.

As you know Bryan, there is a picture and then what the naked eye sees ;D
The cam caps never really have any ware unless the cam has had a problem. The cam is pulled down by the chain and pushed by the rockers.
Never seen cam towers with those markings before, they are usually marked on the sides with a letters .
Trigger:
This is how the match letters or numbers are on most towers. Don't build F2's so, not sure if the markings are different.
These are 100% fecked towers Bryan ;) These are beyond capping and line boring back to spec ;D

Trigger, back in late 70's we had a man who subbed for Dowty and he would grind the cam bearings, bore out the towers and make split bronze bushes that were pegged to the towres and caps. This was when we had a standing order with Fowlers for a complete set of cam, towers and folowers which they could only supply every 2 or 3 months so more common to repair
