If I may ask what presta tubeless valve are you using, didnt know of a presta tubless valve in recent year that wasnt two piece. Maybe I'll learm something

If that is the case I would just pick up a set of stans valves and their injector makes like easier even easier if you buy their core remover it works on both shrader and presta. who caboodle should set you back around $30 really makes set up and maintenance easy. Plus with the injector you can add sealant to shrader and with a little work presta tubes.
