Laverda Dave:
Making good progress 👍

Put your wiring loom in the dishwasher on a 50c cycle with a dishwasher tablet. It will clean it nicely and make it a lot easier to identify poor connections as well as making it cleaner to work on, they really hold the dirt.

Make sure you use a dishwasher cleaner afterwards though unless you want plates tasting of dirt😐.

Engine strip down went ahead as planned on Saturday, fortunately Ash was around at work to help out with it.

Overall the condition of the engine isn’t bad, all seemed fairly clean apart from one piston and bore which would have been the seized one.

I think it was Bryan who mentioned checking the oil filter (on the newbie post) as it’s often neglected, I was finally was able to inspect it and it didn’t look too bad, I’ll put a photo below of it.

The piston bores don’t look too bad, there is some staining on the bore which was seized and a bit of corrosion, but outside of the ‘running face’ portion of the bore, I think it would probably clean up as I can’t feel any visible pits.

Ash has a Sykes Pickavant honing tool which I could use to clean up the bores, but I don’t know what grade of stone I should be using to clean up the bores?? If anyone could point me in the right direction that would be great.

Other than that I need a new cam chain and roller, (managed to get a NOS roller on eBay) since it’s been slapping the wall and worn a grove into it.
New pistons rings one of which was broken into three parts. Full gasket and seal kit for the engine.

I think I got fairly lucky with the engine, there doesn’t seem to be any major issues. Got the long process of cleaning out and inspecting all of the parts then hopefully start the rebuild in a few weeks time.

Bryanj:
Honing takes a bit much metal out use a flap wheel, dont forget Honda piston to bore tolerance is very tight

BenPowell:
Cheers Bryan, good shout on the flap wheel. Suppose it will be a lot more forgiving than using a stone.

Once they’re cleaned I was going to measure the bores to see how much life is in them, ideally want to avoid re-boring if possible. Hopeful they should have a bit with 8000 miles on the clock.

Bryanj:
I commented to Ash that all our restos are never going to get ridden like they were when new, we are propably more fragile than the bikes!!!
