Anyone have any suggestions on how I could remove a bunch of rust from the tank of this 79 250 OR? I have to take care of this project, befor I can get serious about running it! Thanks! Husqrat
best is to clean it up really well then use a high quality tank sealer like Kreem tank sealer http://images.dragspecialties.com/i...play/6a40ccf4-e522-4a78-badc-5234371b14f5.jpg
I used this method to do a really nasty steel tank...... Buy a Kreem kit and throw the sealer away. What you want is the chemical solution, that you clean the tank with before you seal it. Buy a pound of steel BB's and put them in the tank with petcock hole sealed. Add the chemical solution, cap the tank and shake it for all you are worth. Make sure it is sealed well! The chemical and the abrasion of the BB's will take the rust off. I've bought bikes with Kreemed tanks and it's joke.... Usually floating in the tank! The worst was a RZ350, that had the silly little "Unleaded" flap in the filler! I ended up buying a new tank for that bike.
Do a seach on Caswell,they supply a 3 part kit,I also had problems with Creme in the past,the main thing is you have to follow the directions and take your time,its a boring tedious job,to be honest if it was me I would be wacking the tank first in a Pickel tank,engine recon places do it,that will strip it all,paint rust bog the lot.
i just did one on a 74 gt80 i had in the shed a mechanic at work said fill with wd-40 and some nut's like nut's and bolts you can either shake the hell out of it or he said throw in bed of pickup for a few days turning it over now and then and just drive i did both and turn out good
Product that was recommended to me by guys who restore vintage enduro (vinduro) bikes was Evapo-rust.. In the link they explain how to remove the rust from a motorcycle gas tank in one of two ways.. Either filling the gas tank (2.5 Gallon = $45.00 + ship) or pour 1 gallon and rotate the gas tank (1 Gallon = $21.00 + ship) till the rust is gone.. Also available at Harbor Freight (1 Gallon = $19.99).. The stuff really does works..
One pound of salt, one gallon of vinegar, one pound of bb's. Super cheap, quite effective. I just did an XR 80 tank. The most difficult part is getting it all out! I tried a vacuum, but the little lip around the inside of the gas cap make it difficult on an XR. What this did do is expose the weak spots in the tank. I need to patch about five or six small holes on one side.
