Riding into Moab UT with some friends a tvalve started knocking pretty badly. At the hotel I went to unscrew it's cover and the threaded neck striped off flush (holy crap!). Not sure what to do, I pulled of the #1 in order to finish the valve job and it tore off too (j#s*&C$%#@t!)
Next day, bought some RTV to seal the oil in, and some JB weld to glue the covers on. It occurred to us that if I lost one of those covers on the road, I was going to need a tow truck or a whole lot of spare oil so:
One of my co-riders says in his thick South American accent "In Argentina, we use wire like Americans duct tape" He goes into the hardware store, buys a roll of bailing wire and wraps about forty feet of it all around the head and those covers, then JB welds it in place.
Finished the ride through Southern Utah and Arizona with only mild oil leaking
Ever after I'm calling the bike "The Argentinian" and using bailing wire for something (currently as a cotter pin on the rear wheel).
