For those who may have had the same problem, I had to repair a leak in my fuel tank yesterday.
Turns out the PO had had the tank repaired but somehow failed to tell me when I was looking at the bike (surprise!). The repair was on the underside of the tank at the right front mount and looked like melted wax that had rehardened but was not visible without pulling the tank.
Anyway, after smelling gas for about a week and not seeing any leaks by carbs, etc., it finally let loose after a three hour ride and started dripping down along the edge of the tank onto a hot engine and exhaust pipes (fun!). Having never pulled a tank, I was nervous about breaking something but had no choice. Five tubes and three bolts later, my just refilled tank was now off the bike. After hooking up a siphon hose to a spare gas can to empty the tank, tragedy was averted.
After calling a few shops to see if anyone locally could install tank lining (no one seems to know anyone) I decided to to take one shop's advice and just try to repair the leak (besides, not being able to ride really sucks
Anyway, after checking this forum for options and talking to a few more bike mechs, finally settled on using Permatex Instant Gas Tank Repair ($3.99 at NAPA). It's like TV's Magic Putty but for gas tanks (fuel proof...no pun intended) and sets hard but flexible (handles vibration/temp changes). Cut off a piece, knead to activate it and press into place. Five minute job, leak repaired.
I'll probably get the tank relined at some point but looks like I'm set for now. Don't think I'll have issues later, but I'll let everybody know if I do. For $3.99 I get to ride for a while PLUS I learned something new like how to pull a leaking tank off a bike in 5 minutes or less!
Anyway, thought I'd pass this along.
