Not updated this for a while! Stuff has been happening in the backgrund, albeit slowly.
At the weekend I decided to remove the fuel tank as at some point it's going to need a clean up and paint so it was a good time as any. I knew there was old fuel in there which turned out to be a gallen and a half and it stinks! Taken two days to get rid of the smell off my hands.
Turned out good and bad(ish) news. On the outside there is a few scabby bits as I whould have expected. The drivers side is a great mud trap between the tank and side. Looks like the rear wheel throws mud and crap up there as it also taken the paint off the tank on a corner. I may look in to some sort of plastic sheild to help stop that. When I refitted the straps last time, I put two strips of flat silicon on each tank strap to avoid metal to metal contact. That worked a treat as the tank underneath the straps was as good as the day I fitted them. The inside of the tank is going to need de-rusting. It isn't that bad yet. The bottom is actually rust free. It is full of crap though.
Used Hylomar blue on the cork gasket and never showed any sign of a fuel leak.
The tank is for another day. First need to sort this out:
Looks like it's been in the sea for the last twenty years! 😱
Could be worse, could be paying nearly £200 for a new one. Sod that! Can we fix it? Yes we can! (hopefully)
Scrape off any loose rust first. Put in to some hydrochloric acid (Patio and brick cleaner) to de-rust.
Just takes a few minutes to get this. The bits that are left practically fall off when touched.
Badly pitted but still strong and usable.
Still got to get a few tiny bits of rust still to remove but 99% done.
This is most of what was scraped off first!
The plan is, when all the rust is removed, to copper plate then nickel plate the parts. Just wating for some copper sulphate to turn up. The nickle plating solution I made myself.
The filter wasn't great.
The pipe entry end does pop off which makes cleaning easier which I didn't discover until later.
All clean and ready to reuse for the next 100k.
The resistive track still has plenty of meat on it and resistance checks out all through the range.
That's about where I have got with this.
