@5ten.garage: Fixing stripped spark plug threads! I show you how I fixed the stripped spark plug threads on my 3 wheeler using a time sert threaded insert. We drill out the old threads, counterbore, cut new larger threads and install the insert! These inserts are a life saver! 1984 Kawasaki KLT 110 three wheeler #howto #stripped #sparkplug #fixed #enginerepair
