Mine are 1/4-20 as well. Can't say if this is original or not. I had to Heili Coil one of mine too. Threads were still there but if I were to rely on them they would have stripped out.

Hey guys,

The threaded holes in the gas tank into which the dashboard screws go have stripped out on my KJ. Before attacking the tanks with drill and Heli-Coil, I was wondering if any one else has had this problem, and can give me any guidance on fixing them.

Q #1) What are the correct screws/threads?
Mine had 1/4 x 20 tpi x 2" flat-heads screws. Is 1/4 x 20 correct? Shouldn't they be oval heads?

Q #2) How deep are the threaded holes in the gas tank?
One is 1/2" deep, the other is ~7/16".

Q #3) How much meat is there in the "bosses"?
From looking through the filler hole, the bosses (probably not the correct term) seem to be pretty fat, but I couldn't get a reading on how deep they are. I really don't want to drill through into the gasoline section of the gas tanks.

Sorry for these pretty basic repair questions, but KJ tanks are pretty hard to find, and I really don't want to do anything I'll regret in the morning...

Dave

Even though it's freezing in my garage, I gotta get the bike ready for the show in the next two weeks.
