I had rust in my bullet's tank. The above mentioned process was done. I dont find any rust inside now.

Best is remove the rust from tank completly apply very thin layer of engine oil and get a nickle coat by any chrome guys works preety good.SS-Traveller said the same thing.

...get the inside powder coated. As has already been said, the exterior paint is ruined when they put he tank inside the oven to cure.

The zinc metalizing process does not need to have a curing cycle in an oven. It's like a flame-thrower which blasts out superheated molten zinc onto a freshly sandblasted metal surface, and the zinc bonds on as it cools. The resultant surface is slightly granular in texture, but eternally rust-proof.

The bike was in dis-use for a couple of years and was not stored properly resulting in the rust issue (Visakhapatnam is on the coast and rust sets in quite easily if proper care is not taken). I got it out, did a little restoration and started using only since the past two months.

Thanks for the info on the zin metalizing process. I was not aware of that.

Price depends on the model.. Std350 tank is around 4k without the emblems or knee pads. Just black tank with gold lines and clear coat.

When my tank developed a tear near the side facing the seat. I took it to a welder.
Atif (Ranigunj, Hyderabad, 939109-9990) does stuff for bikes.

He cut open the tank. Added a new layer of metal to make it bigger.
Total capacity is around 18 liters now.

Then I got the tank painted by Hira (9290118319).
Hira's shed is close to Ranigunj area on the necklace road side.

Sudipto: You might try and find such a welder in your city.

I am very happy with my new tank.

[Gansan]

A lot of people used to add a little 2T oil in the petrol to mitigate this. Another option was to add a magnetic fuel filter.

[Slick]

@sudipto,

I had the same issue in my Rx100, I got an epoxy coating done from the inside.
The bike is fine now, earlier I faced the same issue of engine starving because of rust clogging the carb.

The same has been mentioned in the thread earlier. In case of a tank tear, like bblost said get it welded.

How much does this magnetic filter cost? Where can I find one? I need one for my 74 yezdi type b...

[Gansan]

^^ May be around Rs 100 - 150. Has to be connected in the fuel line. It can remove rust, but the magnet has to be removed and cleaned from time to time. There will be a provision for that. Looks wise, not aesthetic.

I am looking for this product, any idea where i can get similar product in India.
Thanks in advance.

Hi folks, I am new here.
I have a cheaper way, that I have tried already.

ELECTROLYSIS.

You will need 1/2 of washing soda, a bucket of water or a half of it, a battery charger, wd40, an old drive chain.



1st - Remove the fuel tank, drain it and seal the fuel outlet.

2- Dry the tank for a while and spray the entire 50ml/100ml wd40 and put the chain inside the tank.

3- Shake it a couple of times, let it settle down.

4- Now shake it like hell, take breaks and keep on shaking.

5- After an hr or so, drain the things.

6- You will see a lot of stuff coming out.

7- The chain will be easier to pull out of the tank than nuts and bolts, I even used keys, stones, a knife, just whatever I found handy.

8 - Repeat the process and let it dry.

ELECTROLYSIS

9- Add the soda to water and mix well.

10- Fill the tank with the mixture.

11- Insert a non painted iron rod in to the fuel inlet and make sure it doesn't touch the body.

12- Attach the + terminal of battery charger to the iron rod and - to the body.

13- You may use the battery of your bike alternatively.

14- It doesn't drain the battery completely.

15- Once connected you here a low shhhhhhhh sound.

16- Leave it like that overnight.

17- Carefully remove the connections and drain the tank.

18- You will see a brand new inside, mark my words.

19- But it's still steel, so will instantly attract rust, wind the chain with a cotton cloth and spray some wd40 inside the tank, throw the chain inside and shake it.

20- I don't prefer painting it or coating it with epoxy, cause it would surely chock the carb one day when it starts getting peeled off.
21- Fill the tank to the maximum to avoid rusting.

22- I have installed a selfmade additional fuel filter system and in both I have dropped two magnets which don't let the rust flow to the carb. The secondary one is made up of glass, so I can easily monitor it.



But the fuel cap sucks, it lets peterol to pass while holding the tank upside down. So it would surely be letting the peteol vapour escape when the outside is hot.



Does anyone have a solution for this?

Fuel tank caps have a breather hole for releasing built up pressure and vacuum when the petrol is being consumed. I recently bought a new fuel tank as the old one had rusted to the point that it had pinholes.
