TOPIC:

Its not a weld in cap its a straight bolt in one. I did have a bandit600 cap with drain tubes and breather etc but I couldnt find a welder willing to take it on so I found a place in England (thank Z1OCUK) that sell bolt in caps. I posted a picture earlier of the first one I got but that wasnt going to work,as it wasnt waterproof(!) so I changed it for a sealed unit with a seperate breather.Looks pretty much the same only it has a lock and its in silver rather than black. (Ill probably reanodise it black ). Just waiting on the posty.

ah sweet !
guess i hadn't realized that.
i welded one in my buddies tank that we removed from an old rz tank.

Well,it finally arrived.Again,not the one I ordered (no lock).The quality looks good but I cant recommend these people based on the length of time it took to finally get the wrong one again!
Anyway,I decided to go with it rather than risk returning it and waiting,god knows how long to maybe get the locking one I wanted.
This is a sealed cap (hopefully) with a seperate breather valve.Ill run a hose off that to somewhere up by the clocks, a la early GSXR or dirtbike tanks .














Then my camera battery died.So,no pictures of the fitting process but ill post some fitted and finished pictures soon. It was pretty straight forward anyway and Im happy with how it came out. Now I can start thinking of paint.

Just did a big post and the computer eat it!! Bollocks!!!!!!!!!!!!!!

New tank cap fitted






So,I took it out out again for cleaning and derusting the tank.Going with the brown vinegar again.Heres how it looks

and heres 15liters of finest(cheapest) brown vinegar,ready to go in.

The old neck as a test piece



Ill give it a few days and see how it goes

How do the nuts stay in the tank, if you see what I mean, I can see that you need to cut a hole for the cap and drill holes for the bolts, but how do you get the nuts on the bolts.

I'm interested in fitting one of these to my J

In the first photo of the previous post you can see the a 'C' ring. This has the nuts welded onto it. It goes inside the tank and you bolt the main body down to that ,sandwiching the tank skin and a rubber gasket in between. The opening in the 'C' goes to the front and allows the breather valve space to be mounted. Hope that makes sense.

Bike looks amazing love the seat!!!

Loving the tank cap, I might have missed it but where did you pick it up? I love the more modern style, it matches my intentions but I was hesitant to cut and weld on as others have done, this bolt on options looks fantastic!

Heres a link

but like I said earlier,based on service, I cant recommend them

A quick update. I put the ( untaped ) loom back on the bike a while ago and everything seemed to be working ok. I took it all off again to give it a good clean and sort out all the old connections and replace the dodgy wires. It looks well now.fresh insulation tape and shrink wrap where I could fit it. All the old tape and goo is gone. I put it all back on the bike at the weekend for a final test before wrapping it up and of course nothing is working!!!!
Im sure (hope) its something simple,I just have to trace it,so, back to the schematics again.

Other news. The vinegar is merrily reacting away,doing its thing. Not there yet, another week maybe. Though I cant see much of whats happening inside the tank,the test piece I have sitting in a jar is looking good. The bad news is now I have a hole in the tank.Bugger!!!! Right behind the bracket where the LH badge mounts. The vinegar started weeping out the other day so I poked around a bit and it started more than weeping.I slathered a load of silicone kit over it to keep the vinegar in until the inside is clean then Ill have a better look at it.
Hope Im not looking at a new tank. Any suggestions/solutions welcome.

that silicone will need to be cleaned off very well before you try to pant it .

No Leon the silicone is only temporary to stop the vinegar leaking out. Painting has been knocked back (again) until the tank is derusted and the leak is sorted. Itll probably be a while!
