Go to Harbor Freight, look for the gas tank sealer. I stick of sealer for $2.50. Works wet or dry.



That, or a can of Permatex Motorcycle Tank sealer for $15.00. 24 hour dry time.



Where's it leaking from? The seam? Gas valve?

I've done this twice over the years. If the tank is steel drain it thoroughly. Wire brush the paint off of the cracked area. Make sure that you expose the entire crack, looking especially for any hairline crack. Then wash the tank out thoroughly with soap and water. Put a garden hose in the tank and run water through it for about 10 minutes. That should eliminate gas fumes. Then take it to a professional welder and have it brazed. Then paint the exposed metal.



Both times I did this the tank never leaked again.



If it is plastic then you are shyt out of luck.

i had the worst experience w/Kreem...the guy who did it didn't put the solvent in for a long enough time and the kreem peeled off/cracked and then ended up fouling my pet***** and carbs...now the bike awaits a tow to my friends house because i'm giving it away.

c'm ooooon, if it's rusted enough to eat thru in one spot doesn't that mean entire insides are shot or soon to be shot? chemical stuff will do it? i think leak is close to a seam, somewhere on bottom, i was having a virginia slim at the time and ran screaming from the area like a girl...

That Kreem stuff is crap, it has flaked off in every tank I, or my freinds have used it in.

If the tank is metal, have it welded.

My experience with epoxy based sealers is they will work for a short time, but the extra vibrations of a motorcycle have them cracking and leaking again.

Don't use the Kreem stuff ever, its a good way to force you to buy a new gas tank.

No. Always use Kreem! Treat your oil with Slick 50. When engine performance fades with age use Mechanic-in-a-Can to revitalize it. Use Bardahl, too!

Of course you ran screeming like a girl. Smokin that durned girls sig. If you where smokin a manly sig (marlboro, winston, unfiltered camels etc) you would have finished the smoke and put it out right where the leak is to make the spot, and then swallowed the butt because you don't want to litter.

Since I fool with old metal tank dirt bikes Ive dealt with this problem several times.Ive had bad luck with "home repairs " and Kreem. Take it to a good radiator shop. He will braize it up and coat it...has worked for me.

I used Kreem on my SRX tank about four years ago, and it worked fine. It was an especially necessary deal because the tank was modified to get bigger carbs to fit and the weld of the new bottom could have been better.



Yamaha sells a two-part product that is reported to work better than Kreem. I'm going to use it on the Z50 and see how that goes.



Good luck, Monsieur Burns (I thought of you this morning when my friend showed me his brand new XB12 Lightning...he's happy as can be, and I'm looking forward to when he'll let me try it out).
