Blew a fork seal last week. I couldn't find the torque spec for the drain plugs in the manual. Tightened them and then hit 'em with an impact driver (I was advised this was a good idea). Next day some oil around the plug. Plug spins freely. Oops. Got a helicoil at Autozone. Drilled it out using the specified drill on the package 21/64's. Tap spins freely. Look at tap which says 17/64's. Oops. Good news is 21/64's is the drill out for a 5/16's so now I have a hex bolt instead of the stupid metric (8mmx1.25 in case anyone needs to know - that was hard to find out on-line) phillips heads at least on one side.
But now I'm back where I was before. I can't find the torgue spec on the drain plugs in the manual

Thanks!
Feedback: I tried the teflon paste, but the threads were stripped too badly for it to stop the leak. The cost of replacing the chrome fork leg was $189, quoted from the Dealer. Figured I'd try JB Weld as a last ditch fix before shelling out the big bucks. It worked like a charm. Only drawback is I have to disassemble the front fork if I want to change the fork oil in the future. I'll worry about that in 20K miles.
