Hi Everyone,
WHAT HAPPENED!I look away for a day or so and a whole page of
Fanatics have filled a page and I couldn't get a word in edgeways! What a Dreamer!
David Lahey wrote:I am starting to work on a couple of TY250A (steel) fuel tanks and was curious to see if I could tell if there was any bog in one of them.
The nice-looking one is original paint and has never been rusty inside - 2389 grams.
The yuk yellow one is dented and looks like some of the dents have been pushed out using a tool inserted through the filler hole. It has a coat of yellow put over the dented areas with the
decals masked off by a previous owner. From what I could tell by looking at where I could see under the yuk yellow, the original paint is still underneath. It looks like it has never been rusty inside - 2386 grams.
The unpainted tank has been rusty both inside and outside and been treated with acid and had pinholes soft-soldered all by previous owners - 1810 grams.
From this I'm fairly sure the yuk yellow tank has no bog and the unpainted tank is not very robust.
My plan is to pull a sharp dent out of the yuk yellow tank and redecorate it. Still deciding what look to give it.

David, As you can see, I am struggling to keep up. You have me curious about your
"A" model tank, which dint removal method are you using and am I too late to see?
Continuing on my
GREEN THEME for 2008TEEN, I have been riding
FrankenKT. Last year when I rode it before storing, I was a little careless when parking it against a sapling on the throttle side. Poor bike was pointing downhill in 2nd and it inched forward turning to the right and fell on the left, leaving an impression in the tank the shape of the ground it fell on, Damn!

Any suggestions?

I'd be surprised if that wouldn't pull out easily using one of those 'panel suckers'.
See your local friendly panel shop? Or DIY...

Thanks Rod. That looks promising
Any chance you could post a pic of the underside of the 183 head please?

Hi Everyone,
Greg I have had some success with compressed air with shallow dints like that on the
KT. I did a
TL125 tank and blocked all the exits & at first I put too much air volume in and the tank splayed out somewhat.
However the process did work after having to re shape the tank back.

Yes Chippy, but the danger is that that technique can blow out good seams.
EEEEeeek!
The actual problem is that with compressed air you can't control WHERE the compression happens, so it's just as likely to split a seam or push out a good area as fix the dented bit.
Maybe if you heat the dented part to soften the metal there then pumped it up...
I'm a sucker for the sucker.

I took photos but it's not pretty yet. I welded an 8mm nut to the dent and applied force to a bolt screwed into the nut while heating the tank strategically. I plan on posting when there is a pretty "after" photo to go with the yukky magnetite-coated-steel photos
