The ongoing saga of the GS rebuild post repair of clutch and input shaft....

Took the bike out today after running through gears. Started to run rough fairly quickly and then died, prompting the walk of shame pushing the bike back home (luckily only just got down the road).

I'm sure there's a fuel supply issue, so will pull injectors again and am thinking of cleaning out the tank as may be contaminated fuel....

Main question - my fuel gauge constantly reads as full (only about 6 or 7 litres in there). I was hoping this would miraculously self rectify, but obviously not. Any ideas what the cause of this might be, I'd have thought if knackered would read empty....
 
Bruce, I know its not the same but I had a 5 series that read full when I bought it from a salvage Co. It was only the locks that had been damaged and I soon had it on the road, I drove it about 15 miles and it ran out of juice but still read full. I filled it to the brim and drove it as normal and the fault did go away. I think in my case the car had been drained to near empty whilst sat in the yard and the float had stuck in the full position.

Hope yours is as simple to sort and good luck with it, I would deffo drain and flush the tank and fill with fresh petrol.

That's also a good suggestion.

Opened up the fuel tank and noticed the paint inside has blistered and is peeling. This may be partly what has blocked the injectors again. Any ideas?!

Doesn't look good but I would think that big lumps of flaky paint would be trapped by the fuel filter.

They may well start as big flaky bits but agitiation breaks them down into much smaller particulate, and it can get everywhere, which is a nightmare. This is know.....:blast

You gotta sort that tank out.
 
Any suggestions? I've read about chemical strips for the inside followed by sealant, but the GS tank would be quite a difficult shape....

The first thing I'd check is the fuel pump gauze.
That way you can rule out/confirm where your problem is.

Nothing worse than getting the tank internals fixed to find it's still got the same fault.

Your tank may have been like that for years and may be ok for years to come.:D
