Rusty tank - Pirate4x4.Com : 4x4 and Off-Road Forum

Kellydayz · 06-01-2005, 09:57 AM

I picked up this bike the other day and I would like to seal the inside of the gas tank. My searches have not turned up much yet.
Anyone have any tricks or tips for removing rust from inside the tank? Any suggestions on a good paint/sealant?
Also, anyone have any info on this style Kawasaki 100? The previous owner thought it was a 76 but was not too sure. Thanks

You can put a short length of chain inside the tank and rattle it around for a while. I have put coarse limestone rocks inside an old B/S generator's gas tank and rolled it. Then poured those out and put in some sand. Poured that out and cleaned with water then acetone. To seal it, I used some stuff from the Eastwood Company.

get some ball bearings or some washers (bout 10-20 of them) and put them in the tank (once u take the tank off) and add a little diesel and shake it baby!! shake that around for a good while then pour it out and repeat if nessecarry!

You can also put a couple handfuls of drywall screws in there and shake the tank.

Thanks for the ideas, I will try the diesel and screws/washers/chain/sand tomorrow at work.

From what I've read also, CLR works well for cleaning the insides of tanks to. I need to clean the inside of my RD350's tank one of these days.

My uncle has a 90 he bought for his grandson. Was enduro tho, so it was street legal at one time with blinkers and all that. Will do about 50-55 if I remember right, wound out. The oil injection in his wasn't working so the guy he bought it from was mixing. Pulled it apart and it was plugged fitting at the oil pump. Runs great have fun with it!!

Use this method with some laquor thinner (make shure your tank is sealed first!!) It works best. I have done it countless times...... Have to when you restore old bikes.. The sharp edges of the screws are the secret

Thanks for the ideas. I endeded up using 60 drywall screws and 20 washers and diesel fuel. I shook till my arms hurt. It did a real good job of cleaning up the tank. I took a pic of the diesel, not sure how it will look on here.

Now to dry the tank

Kellydayz · 06-02-2005, 12:26 PM

I filtered the diesel just to get an idea of how dirty it was.
I also bought some Damon brand Red-Kote fuel tank liner at $23. a quart

I'm letting it air dry a little more before I try and line it.
