Great attention to detail always pays dividends. You mention Nitromors I dont think that is as effective as what it once was. They must have changed the formulation. I tried it on my workshop floor to remove paint over spray that had built up over years but it had little effect.

I am partial to an Irn Bru myself when I can get it.

Another update.

Been a busyish week, again. I seem to have spent ages sorting out the cylinder heads. I have the two that came with the bike, I have two from a spare engine I bought a long time ago, and two that came as a part of a load of spares when I bought the bike. All have been stripped and inspected. One was a right off. The spare engine had been in a crash, and suffered damage on the RHS cylinder head. One had worn valve guides, two had pitting around the sealing face around the combustion chambers. This has left two which are fit for purpose.
The valves were cleaned and lapped. The valve train was stripped and the shafts swapped round to minimise the wear. When the rest of the cases go for vapour blasting, these will be included.
I was talking to a mate about the pitted sealing faces on the spare heads. He pointed out that some of the aftermarket cylinder head gaskets appear to be the same size for all the 4 cylinder bikes. This would leave an area not covered by the gasket on the 1000 and 1100 engines. I have only ever used Honda gaskets, so never noticed this problem.
Is it possible to skim the face of a wing cylinder head. Is there enough meat to allow sufficient clearances. The pitting looks to be around 0.25 mm ish.
When I manage to get the new workshop sorted out I will be looking to have a go at replacing the valve guides. Never done this before, so should be an adventure. I will try the scrap head first.

Sorry no pictures this week, will do better next time

I have heads resurfaced all the time. No issues.

Changing guides is easy. But know that if you do you will then have to get the seats recut. Any good machine shop can do that. It is pretty rare for these guides to be worn. Might want to check the valve stems first. Those will usually wear before the guides will.

I've even resurfaced a head and the mating block face with files and sandpaper on glass. Machine shop is the recommendation, though. BTW, LIGHT lapping. The valves have very thin stellite faces that are very hard to increase their lives.

Hi There
Thanks guys, all noted.
The valves were very gently lapped, just enough to get an even ring on both faces.
I will have to find a good machine shop to face the spare heads, a task for the winter I think.

Hi There

Been another busyish week here.
Looks as though I might be getting out of shielding soon, so I have been working on my 18. I don't own a car, so if I want to go anywhere when released I had better fix it. The alternator decided to throw the towel in just as I went into lockdown, together with a wet patch on the garage floor. Looked into this and found that the water pump had also decided to call it quits. Just as well the alternator had to come out as the starter motor also has to come out to allow removal of the pump.

There was a mix up with the parts order, which should arrive tomorrow.

Been working on the 11 as well. Had a look at the wear in the bores. Bore gauges are not something I use very often, so it has been a bit of a trial and error kind of thing. I think I have the correct readings now.

And here are the results. All seem to be within spec, but I will hone out the bores again and take another set of readings. Don't think that will be this week though, the 18 is a priority.

The workshop is still ongoing. I have had to increase the size of the garage back door.

An airbag model? That has to be LOTS of fun!

Not good. I wouldn't want to do this for a living on a regular basis.
It is an airbag model, it was the only type sold in the UK. It has done 86000, so not too bad.

We have over 123000 miles on our '06, and the only work other than scheduled maintenance was replaced splitting seat and speed sensor - both under the extended warranty. I measured the valve clearance four times now. Changed a few shims after the second check, none needed after that.

Shielding partially lifted, so was able to picked up the new alternator yesterday.
Going to be scuffed knuckles and swear words this afternoon.

So, been away for a while.
18 is now running fine, not too many scuffed knuckles, but the swearing went well.

Don't know about everybody else, but I have been living quietly due to the pandemic. Now I need to get back to doing something more rewarding, so back to the 1100.

Had a good look at the wiring harness. Not too bad condition. replaced some of the outer tape, removed the terrible IDC DIY connectors and refitted the original push connectors that were missing. Cleaned all the connectors, some needed the HP treatment. Main harness is now back to original.
I had picked up a new horn harness from CMSNL a while back, and picked up the correct horns on E Bay, just waiting for them to arrive. When I bought the bike it didn't have the right type fitted. I dare say these will need to be refurbished.
The other harnesses cleaned up fine, Just need a new piece of heat proof wire for the neutral switch, this was damaged.
The only sub harness that needs replacing is the 3 wires going back to the tail light. This had been totally butchered, but will wait until the rear mudguard is fitted. I will be fitting Honda panniers, so no need to run indicator wiring to the back.

Getting to the point where I need to use outside help. A colleague has a small vapour blasting business and he promised mates rates, so all the engine cases will be going off to him. The frame and sundries will be going for powder coating when I am allowed to travel. Its a long story.
Wheels are inching up the to do list, not too bad but will need a fair bit of cleaning.

Not wanting the belt covers to be polished, just brushed. A mate who lives just round the corner knows far more about this kind of thing than I do, will be keeping me right.

There you go, the devil makes work for idle hands. Can't wait
