Nice idea, but the studs aren't long enough for double nuts.
Sound like a personal problem to me
I found those nuts you pictured earlier, ARP brand at a local hot rod shop. I got them for $2.25 each. So next time I tinker with the bike they are going on.
I'm always paranoid about those things falling off since I upgraded the exhaust. I check them about every 500 miles just to make sure they are still tight.
I ordered 4 of the Aircraft nuts in the link (Thanks cHarley).
Maybe I can rest a little easier knowing they're on there.
can these
thx - tin nuts be re used when tinkering with exhaust or are they a one time use?
