[ARC5] Military bolts

[Gary Pewitt]

Years ago I bought a Triumph 650 with the typical oil leaks.  I drilled 
out -every- threaded hole and re-tapped to the next largest size with 
American threads.  I put it back together with RTV sealer and Allen head 
cap bolts and I had the -ONLY- Triumph in the USA that did not leak a 
single drop of oil.  It can be done.
