Handlebars riser install questions, please

This is reference my 2016 Speed Triple S.

I am installing a set of SWMOTO risers. These came without instructions :-(.
Would anyone have access to proper torque settings and is there a suggested pattern or order of tightening these longer bolts?

The bike currently has a one piece top clamp but the risers came with individual top clamps. Are there any pros or cons as to using the original one piece?

Thanks for any facts or speculation.

CHEERS,

Chris

PS I did cross post in the technical sub forum hoping for wider coverage as I'd like to get this done.

 

Update for all you 2016 Speedy owners. I bought the SWMOTO 28mm dia. with 30mm rise in the silver color. They fit perfect and do not restrict the cables. Easy install and I got the correct torque setting which is 23 nm. I love the ergonomics and I no longer am sliding forward in the saddle as much.
