TOFTY - liking the renders of the axle stand and the footpegs
but have you noticed the symetry of a KR head - for manufacturing a custom head it's going to be far simpler to make individual heads. (negating the KIPS cable mount)
The old YPVS mod - whether its beneficial to longevity - certainly probably better for piston to bore alignment and never warps heads.
Its a 10 minute job to hack saw a head up, cleaving off the themostat housing.
Then weld up the wall along each head where the thermostat was cast.
Lathe two tubes out that will become the new water outlet at the top rear most of each new head - weld into place. (source suit bends/hose to determine new outlets diameter)
If you have a meltdown on a particular cyclinder you now have only a single head to replace rather than throwing away a good cyclinder head on the twin set up. For those already with damaged combustions lying around this will make use of half pitted heads (use the good half).
Also becomes alot easier for someone to machine the correct squish clearances for each barrell.
Consider the radiator Y bracket to be made out of carbon fibre or plastic that would be more flexible than the pressed steel original. The purpose is allow individual expansion
Reuse part of the thermostat housing and have a backside made for it with 2 inlets from the INDIVIDUAL HEADS.
when you need a new head gasket tell them you only want to order half of one. (':-
