How would one such as yourself go about cleaning out and relining a gas tank that has been exposed to the weather, I am talking about inside don't care much for the outside yet

The petcock needs to be cleaned also from the looks of things, might just get a new universal one and get new o rings...still debating on that

Are you talking about having rust inside the tank????

Yamaha makes a tank rust remover that works great. The first product etches and removes all the rust from the tank and the 2nd part of it neutralizes and removes any moisture remaining. Its about 20.00 or so and works great.

Others may mention Kreem, but I like the Yamaha system better.

As far as the petcock - remove the petcock and clean with kerosene or diesel fuel and change out the o-ring seals and you should be good to go.

Have used Kreem and was pleased with results. Not familiar with the Yamaha system. 1Adam, does it also reline the tank?

YAMAHA does not line the tank
only KREEM lines the tank.
ive used KREEM in 3 tanks and was pleased but if i do another i will use the YAMAHA kit and just keep the tank full of gas. :wink:

The Yamaha one leave the tank as it should look - bare metal. I looked at a Kreem tank and hated the white murky stuff it left behind. When the Yamaha one strips all of the rust in the tank there really is no reason to seal it if it is maintained as it should. My tank is almost 20 years old and you can see the gas to the bottom of the tank and see the silver metal on the bottom.

Keep your bike in a garage or a shed out of the rain!

POR-15 is good stuff too. they all work fine.

Agree with all of you....reason I mention Kreem was that after my cleaning process, seems the tank had a leak in the seam...previously sealed by rust. If you have a mildly scabby tank, a good cleaner would be the way to go, but it seems the problem here is a very rusty tank, petcock included...I would go with a liner material kit.

You can use Kreem with the petcock still installed on the tank??

NO, make a block off plate out of wood/plastic etc. if you use the KREEM version make sure you dont KREEM the filler cap cause it has a VENT HOLE in it.
