If you've owned or currently own a TX750 you will probably be more than aware of the starter clutch issues?
Apparently there is someone called "Argo" that has been producing an upgraded "sprag clutch" to replace these troublesome originals. I have had starter problems myself, to the point I am now unable to ride the bike.
I have been unsuccessful in contacting Argo. I have now since been able to successfully been able to manufacture a conversion kit myself.
I am now considering manufacturing these "sprag clutch" conversions here in the UK. So I am 'dipping my toe in the water' to see if there is any interest out there?
