Plenty of restored bling out there, looks like you could end up with a mint unrestored survivor .... nice

Cheers, however, It's not mint, but certainly in very decent original condition.
I have another brown 900 on it's way, so I can choose the best parts from both!

Had a bit of a poke about the bike yesterday and found that the rear light bulb had failed and was the cause of the stop light on the console flashing.
However, after replacing the bulb the light on the console still flashes.
So I need to see whether the brake light failure indicator switch under the tank is working correctly.

Also, as the bike is running roughly I checked that I have spark on all four plugs, which I do. So the issue is likely the carbs.
I removed the air filter and found what appears to be a home made air filter which uses a microfibre cloth as the filter!! :shock:

Front brake works really well. I checked the fluid and it's nasty, so that will need to be changed.

Inside of tank is rust free with a small amount of the usual brown residue.

I'll be giving it a deep clean over the next few weeks and that will help to find any issues.

Found out a bit of history about the bike. It's had one owner until 2017, when it was sold to the person I bought it from. That original owner racked up the whole 8000 miles showing on the clocks by 1982 and then the bike was mothballed. It was occasionally cleaned, checked and started.

Anyway...

Made good progress on some other things today so had a few hours to take a closer peek 'under the bonnet' of the 900..

Removed the tailpiece to look at the rear sub frame and mudguard. Sub frame a bit dirty but no rust.
Rear mudguard had some moderate pitting, I cleaned ab it up with Quick-Glo fine formula and it came up nicely, so I removed the mudguard and got to work in stripping off the rear light and cleaning it all up fully.
Slight crack in by one of the mounts on the inner rear mudguard. :|
Image

A closer look....
Image

Under the tank shows pristine paintwork. Wiring should clean up to look like new I think.
Image

Rear mudguard cleaned up nicely with Quick-Glo. I also stripped the rear light and bracket and cleaned all that up too.
Image

What's this lurking in the airbox?
Image

Carbs are leaking and full of crud. So I'll be whipping those out to clean and sort them.
Interestingly, I notice the flat connecting plate across the carb tops. My previous A5 didn't have those...

Got a good six hours in today. Carefully removed the exhaust, rear wheel and battery box so that I can get into the nooks and crannies for cleaning.
Also removed the carbs, stripped them and ran them through the ultrasonic cleaner.
Figured out that the issue I have with the rear light warning light is the little controller box. Disconnecting has sorted the issue...

What have I started?
Image

Engine bay is not bad.
Image

Very carefully removed the OEM exhausts!
Image

Battery box is in very good shape with no corrosion.
Image

Under the battery box is decent too, just a bit grotty on top of the swingarm.
Image

Doh! broken tool tray mount... :(
Image

Carbs all stripped. Apart from the gaskets being porous they are pretty clean inside and no wear. The air screw o-rings have disintegrated though. T-pieces look OK.
However, the finish of the carb bodies is not brill. Never seen this before. It's almost like they are plated or coated in something, but the finish is inconsistent. Or the bodies have corroded in some way..
Ran them through the ultrasonic cleaner and they are not really any better. So I'll need to decide what to do with them...
Image

Old dry grease, so will need to repack them with grease.
Image

Rear brake and hub are in good shape, just need a clean up.

I'm impressed on how the chrome came up on the rear mudguard.

Indeed. That's why I took on the rights as the UK re-seller for Quick-Glo!

Cheers.

By way of an update, I'm not happy with the finish on the carb bodies, so going to get them vapour blasted. and get the engine cases polished.
Any recommendations for anyone in Yorks/Lancs for both those?

Agrigg chrome plating in Leeds has a good name. As well as chroming he also does polishing and ultrasonic cleaning on carb bodies.
He might be worth a call, and he's up your neck of the woods. Paul.

Did a bit of fine detailing on the rear wheel yesterday. I used Quick-Glo Fine Formula https://www.airevalleyclassics.co.uk/quick-glo-fine-formula-8oz.html (plug, plug) on the rim and hubs, using a tooth brush to get around the nipples.
Has come up pretty well and should now be protected for some time.
Spokes and nipples are dulled but not rusty and minor pitting to the chrome, but no thinning.
