Will it catch fire?

also if you do go down the water track you can use Meths to flush out any residue water, as I believe meths absorbs water or makes it easier to flush the water out then flush with petrol a few times. Safest method take the tank off. after tack welds are called that for a reason they are not permeant and easily reversed with a grinder

just take the tank off and remove it fromm the scene of welding

The safest method is actually ... connect a hose from the exhaust pipe of a car and poke it into the fuel tank (take the tank off First) and run the exhaust fumes into the tank for about an hour. This dries out the interior and removes ALL petrol fumes.

To avoid an explosion the OP really needs to talk to someone who actually knows that of which they speak. FJRider's comment is the first in this thread to meet that requirement.

Where is the fun in that? I mean it's a big job looking up a phone number ......

Hey - at least no one has suggested he buy some porn and commence to fill the tank with sperm. That may actually work as the sperm will absorb any residual fuel in the tank.


I did a bit of Googling out of interest on welding motorcycle tanks and there are lots of questions on multiple forums. It appears you will die if attempting this at home .......

A interesting comment based on some 'book' was steaming the inside of the tank for 24 hours.


But basically unless you are a pro it sounds like a job for one.

I recently had a couple of discussions with mechanics of my acquaintance and exhaust fumes were stated to have long been their method of choice. I seem to recall that carbon tetrachloride might have been used in days gone by, but that may no longer be an option.

Spent the Saturday morning with a professional welder and the job is done! Thanks for your comments and advice. It wasnt as bad as I thought and I also feel like I stepped up my customization game too.

First of all, I dried out the gas tank compltely then ran exhaust gas into the tank for 20-30 minutes for good measure. Despite the precaution, the welder didnt seem worried at all since the job was not actually on the tank.

I sketched a concept then this happened.

I've sanded, primed, putty, paint and clear coated as well.

Will post an image of how it looks like on the bike once the paint dries.
