Progress!
Been beavering away at this one in the last few weeks, and I'm now - hopefully - on the home stretch.
The motor went together OK until it was time for setting the tappets - Combat head and standard pushrods don't match, but I believe that's how they left the factory :shock:
Apologies for the crappy phone photos - I promise to do better when I finally wheel it outside
I've found that holding the pushrods into the head with elastic bands saves about half an hour of faffing about.
When I stripped the head to get the port threads re-sleeved I noticed that the tappet adjusters were showing a lot of thread above the rocker, so expected some issues.
The original inlet valve tops were badly worn towards the edge, and it looked like the tappets hadn't been near the middle of the valves in all its life. Can't have been very good for the guides either, so they've all been replaced.
I assembled the top end to find there wasn't much adjustment left, so I removed 2mm from the pushrods and it all lines up properly now.
Didn't think to take any 'before' photos, but here's the result (note the sexy titanium valve spring collars):
I made up some 'combat' decals, but I'm not 100% sure I'll keep them on - they're only vinyl, so no biggie.
I still need to finish cleaning the carbs up - I'm limiting the work to new hard anodised slides and Viton tipped float needles as they didn't seem to be particularly worn.
Just waiting for a crimping tool to arrive so I can finish off the original-yet-messy-looking fuel pipe work.
Here's where I am as of today - waiting for a new LH switchgear, and I need to finish the wiring, as well as putting the front mudguard on.
Still not sure about the 'combat' graphics... :roll: Perhaps they look OK :wink:
With luck I may have it running by weekend - we'll see!
