I have an 08 frame that has done some sliding on asphalt, and the high point of the side angle is abraded to the point where there is a pinhole leak in the deepest part.

I emailed EBR Tech about welding it, and was told that although Buell never recommended welding because of the lining that would be damaged by heat, they know it has been done a number of times.

Has anyone tried any cold repair methods on one?

I know NAPA used to sell a pretty good gas tank patch kit, but that was 25 years ago, and may have changed by now.

Thanks Two_ seasons.
I've never tried JB Weld on a fuel tank, but a guy on another bike forum whose word is suspect claims fuel softens it.
I could try contacting the manufacturer, I guess.

I need to check with NAPA too, and see if they still sell the same fuel tank patch kit.

All it contained was a section of Fiberglas cloth and some fuel resistant epoxy.

Don't know what you're planning to do with the bike - roadworthy or "pretty", but can you drive a sheet metal screw covered with a fuel-proof sealer into the pinhole? Grind down the screw head and refinish the frame??

Yes, it is easy to do and very effective to weld. I have repaired two crashed frames. FIRST, clean, clean and then clean again. Remove all traces of fuel and leave everything open for 24 hours. Vapor ignition can be very exciting!. I usually cut out the damaged section with an abrasive cutting disk. Then fabricate a replacement piece. I then "V" cut the new seam. I then purge the tank with a 50/50 mix gas Argon/Helium mix eliminating all air. Then I weld up the tank blending the welds afterwards. Of course the tank/frame must be powder coated afterwards.

On edit, seal off all openings and pressure test for 24 hrs at 2PSI not more, before powder coat!
