A forum for owners of Yamaha TTR250 trail and enduro bikes!

Hey guys, I have a ttr-250 and have noticed that my fuel tank has a crack in the top of it after it started leaking when I filled her up. The crack is about 7cm long I would say but it's only a little hairline crack. I have tried the solder iron trick but I can still see the crack, I'm not even sure if this theory works or if I haven't done it properly. Reason being I was quoted $800 dollars for a new tank and I thought that was abit rich. Please if anyone has any ideas or any cheap tanks they know of, help would be much appreciated, Cheers

Thanks Steve, yea that's the other trouble I've had, I'm based in Adelaide, South Australia, and I've phoned many companies about welding my tank. One placed agreed to do it them I phoned them today to find out that they couldn't. Ive tried wreckers also and they just tell me how hard it's going to be for me to find one
Thanks for the reply Steve I appreciate it.

Too easy man,

                     If your going down the Selleys kneed-it road just make sure you roughen up the surface with some 400-600 grit sandpaper so it sticks and clean surface is always good  http://www.selleys.com.au/putty/epoxy/knead-it-multi-purpose#information

Put two layers one small then one over the top of it then you can sand,file,drill,cut or do want you want with it.

Interesting story....

Once i was up in the middle of nowhere visiting a friend of mine and it was a rough road. It turned out rougher than i thought and a big rock bashed a hole in the sump of my Holden kingswood. I had some Steel kneed-it handy as always in the glovebox,so i waited for a bit for the oil to drain out.After some time it was still draining and it was getting dark.

I had no torch with me and was a long way away from the nearest house so i had to move quick.

I decided to wipe it down with petrol and a rag then jam what i could into the gaping hole still pouring oil.

After some effort of trying not to mix too much oil with the kneed-it i finally sealed it.

I still was'nt sure because alot of oil had mixed with the kneed-it

I then scrached it up with a rock wiped it clean again with the petrol and rag and put another big ''wadd'' of it on.

To my suprize it worked better than i thought and lasted me another four years like that.

When i sold the car ''just about a wreck'' it was still sealed and as far as i know it is still sealed today.

Amazing stuff

Here are some other fixes i  have done with no trouble at all...

Side crankcase covers ''even 35mm holes'' Steel kneed-it

Plastic torch light cover multi-purpose Kneed-it

Car Body repairs Steel kneed-it

Copper fittings Copper kneed-it

The other fixes are boring and you'd get the point by now

It has'nt failed for me yet except for my carby support mount but i think that was asking too much  see here http://ttr250.activeboard.com/t50560400/repairing-a-broken-carburetor/

Don't like to bring up the past but it would be good to know what method was used???

Did the kneed-it work or plastic weld???

Jarrah.

Can you get it "plastic welded"? See here

This link - CLICKY LINKY - takes you to an article by wikiHow regarding tank repairs.

It may contain the answer you're after, Marshall.

On a personal note, I have successfully repaired many of my "plastic accidents" (NOT petrol tank) using my electric soldering iron.

What a great tip, I noticed a massive (275mm) crack/split in my tank which leaked fuel when full yesterday and thought new tank or plastic weld job needed for sure. However after reading this tip I have just bought a tube and carried out the following repair (still to sand and repaint) but it's not leaking yet, will let you know if it holds up after a couple of tough rides.

Once again, thanks Jarrah.

I bought a TTR250 on 3 days ago and what do you know as soon as my father touches it, he pierces the fuel tank loading it onto the truck. Cant find any original fuel tanks anywhere and I really do not know where else to look, whether buying the same one or whatever. I am honestly very new to bikes so I have no idea what to do. 

If it's beyond repair then you may get a cheap alternative from a breakers yard - see here

PS And welcome to the forum!

I managed to find a company around the corner that repairs plastics

 

Left it with them for the day

showed me the pressure testing and it was all sweet

another $80 down the drain but much better than finding any other alternatives

 

And thank you for the welcomes, much appreciated

I second that, where are they, Just in case ?

I think you will find that the metal tanks, over a lot of time, have a problem where they are rubbed with the saddle and at times rust and leak.

Repairs with JB have often been shown to work, but must be really regarded as temporary.  

Welding a metal tank is the really sure way to repair - but is dangerous for the amateur repairer. Best entrusted to pros. who know that petrol, fumes and heat are together lethal.

Totaly TTR has a used, refurbished steel tank currently HERE

A much safer, neater and cost effective (£40 plus post) repair.
