Not really a project - but have been transferring everything from my KR1 / KR1S hybrid on to a new frame (old one had damage) since just before the winter.
Sprayed the new one and polished the main frame spars.
Everything has been checked/cleaned/sprayed/lubed as required as i went along. Replaced most of the manky fasteners and put good
a lot of neglected jobs over the years.
Almost finished now and looking forwards to starting it up and refitting the body work.

often wondered, is how much stiffer the KR-1S frame is to a KR-1
second moment of area says about 9.4% stiffer
the 0.7mm thicker main spars will add estimated 400g to the KR-1S frame weight

on my old B I filled the frame rib depressions with black vinyl strip (kitchen draw vinyl)
also around swingarm pivot
saw someone do it once on the original old e-box ZX-10
quick and simple mod makes the KR-1 frame look more different and 3 polished ribs will really pop. since you are going with black accent vs polish
Pity I couldn't find a 1S frame for my project- a 9% increase in stiffness is a worthwhile gain which more than compensates for the slight weight disadvantage.

factory frame mods to other bikes: road to race trim (such as YZF750) included welding plates on key areas to stiffen.
the 9% stiffness KR-1S advantage could be eliminated between the two by doing either of following to a KR-1 frame...
1. glue a 80 x 1.2mm sheet along the inner face of each beam
OR
2. glue/weld a 20 x 2.5mm strip along the top edge of each beam section
I suggest glue/bonding because unknown what weakening affect welding could do to the frame over large area.
BUT I wouldn't bother - less weight is better. Nothing wrong with a KR-1
