I am looking at buying a 03 M800 for a very low price because it was dropped. The only problem I'm not sure about fixing is there is a crease in the dent in the tank that leaks slightly. I am thinking of using JB weld or some other product to repair the tank temporarily until I can afford to fix it right. Anyone use JB or any other epoxy type repair kit?
03 m800 = plastic tank, right fellas?

I thought it would be metal. ???

Should be metal.
Definitely steel...
To the OP.
You may get away with a JB weld repair, but...
surface prep and application has to be perfect.

Def is metal. Thanks for the reply. I see other tank repair kits(like victor), but I think JB weld will work better. Oppinions?

I only use it if I'm also coating the inside, and then only if the customer insists. I guarantee my work, so I don't use "shortcut" or temporary repair methods.
Not familiar with that product. Have a link?

It is a two part system, I see it advertised as for sale at ace hardware. It looks like two past sticks.

I'd use the JB weld I think.
It will 'flow' into the repair area better than the thicker stick type IMO.
Nate,
It sounds like this tank hit something with a sharp edge and has a dent with sort of a slice in it. How would you repair this permanently? I think I'd try to braze or OA weld it. Depending on the dent location I've heard of some guys going to the effort of cutting a hole in some other area of the tank so that they can get a steel rod inside to knock the dent out. Then repairing the hole of course. I've had mixed results trying to knock dents back out of bike tanks with a rod through the tank fill hole.

Bob...
That is one way to do it. Access through the filler hole is always limited, but even more so on Duc tanks due to the airbox relief. I personally think adding holes is counter productive. I use a stud welder from the outside. You can do really nice work with one if you take your time. Once the dent was pulled I would use an electric process to weld the 'slice'. OA welding adds too much heat IMO. I own a mig, but tig would be easier. I don't do enough of those types of repairs to justify the cost of a tig machine. I would then finish the job as normal with an internal coating.
Thanks, the stud welder is a good solution. I've used one on an old truck in an area that was only accessible from one side with great results. Guess I just forgot about it. I didn't like the slide hammer collet thing that was supposed to grip the studs so I modified the slide hammer to hold a pair of vise grip pliers. That worked good and had a much more positive grip on the stud.
This is the bike. The circled area is where the split is. There is a lip from the upper part of the tank overlaping the lower edge of the split.

That tank needs ducpainter's loving touch. You will get it back better than new.

I think you've hit the nail on the head, here, Ducpainter. I believe that any fix of a leaking fuel tank involving less than a weld repair is irresponsible and dangerous. Opinions vary, but that's mine. I'd use TIG if practical.
My 2 (OK....4) cents.

Those have gotten much better, and smaller, since they were first introduced.

That looks like a stress crack as opposed to a 'cut'.

I think it was me, not Lowthudd, that suggested it might be a slice or cut from a sharp object, before we got the picture. Surprising that the steel cracked like that by being folded, it must be an alloy or higher carbon content and is more brittle than a basic mild steel.

Aside from the damage that tank is great [drink]
LOVE the black and gold, shame to see it like that... Ducpainter's work is amazing, he did my tank and I am very happy with it, I'd send it off to him.

I'd love to...and most likely will eventually. But I just can't afford it right now. My goal is to get it rideable for a few months until I can afford to properly fix it.
you can just buy a spare tank... i have one if it fits. it has a dent in it.

WHat year is it? Needs to be a 02+ I believe to fit. Please correct me if I am wrong. I am interested if it will fit.
From the pics that looks like a good crack/split. That could be big enough to move and crack open again if you just plug it with JB weld or similar. I find JB weld or other epoxy tank repair putties to be best for small areas that either rusted through or punctured but are otherwise sound.
If you really need to get it up and running take it to a tank shop and see how much they would charge to just weld or braze it up without knocking out the dent. Then rattle can paint for now. If you do try to JB weld it, drill a small hole at each end of the crack. That allows any stress from the end of crack to distribute over the circumference of the hole instead of concentrating at the end of the crack where it would tend to let it spread.
Ducpainter, am I overanalyzing here?

From an up close(but amatuer) inspection, it apears as though the metal at that crese folded over its self, and the scraped to make a small leak. The leak is extremely slight, hardly noticable. I don't think it is a stress crack. The is a sharp edge on the lip of the crease from grinding against the ground(?). I don't think it will spread, but I'll look at it more closely once I have ownership of the bike. Thanks for the input.
Ok, looks worse than it sounds. Still, a braze touch up will last indefinitely, JB weld may not. Good luck!

its an 02+ steel. According to the Tank thread ( see Acc and Mod or Tech stickys) it will fit all 02-05 bikes, and some 06/07 bikes (plastic tanks) I had the intention of borrowing a stud welder and pulling the dent, then blasting the surface paint away. Give it a slight polish and clearcoat. But Ive fallen out of love for my monster to care to much about looks. PM me if your interested.

Scott,
You're not over analyzing...
but you are forgetting that heat applied to the tank in its' present condition will make the repair more difficult and the possibility of cracks due to heat induced brittleness more likely when the dent is pulled/straightened.
Plus...
a stud welder can't be used over brass.
To the OP...
I'd try the JB weld repair. It costs little and has a chance of working.
If it doesn't...
winter is almost here... [thumbsup]

Thanks, will do. And I'll PM you when I am ready for a repair/paint.
