I can vouch for central wheel components to convert tubed into tubeless.
Had it done back end of april so far so good on my thruxton R.
Was also a good opportunity for me to learn replace my brake pads, clean the calipers and pistons, adjust and clean chain, setup wheel alignment as garages wouldn’t let me leave my bike on stands for a couple of weeks.
opportune timing as tyres needed replacing anyway.
Yet another excuse to buy additional tools 
To my delight I can now carry a puncture repair kit.
i’ve seen plenty of posts in favour and against conversions but central wheels do moto X conversions if its good enough for those boys then its good enough for me.
I would steer clear of DIY conversions, for safety reasons, and inconvenience of not getting it right v what price central wheel components charge. No brainer IMO.
