Well in theory...on a conventional symmetrical wheel the center of gravity is in the middle of the centerline of the axle. Each side of the rim is equally close to the CofG and so neither side is preferred for adding weights and this also gives good opportunity to correct dynamic imbalance if needed by adding weights to either side of the CofG. With a dished wheel like that of the GTS the CofG is actually a lot closer to the side of the wheel where the weight is concentrated, probably fairly close to the RHS edge (sitting on the bike) of the rim. It would make sense therefore to add weights needed for static balance to the edge of the rim closest to the CofG to avoid upsetting the dynamic balance. The other edge of the rim is relatively a long way from the CofG.
Having said all that, due to their narrow section, dynamic imbalance is not often a problem on motorcycle wheels. I have used stick on weights and as I've discovered, it's difficult to put them anywhere but on the "wrong" side of the rim. I tried once to put them in the center of the rim but there isn't enough clearance to the brake caliper. Even so I've not encountered any out-of-balance problems. If I were having balancing problems though (especially a shimmy), I'd try the factory weights, because the particular state of balance of my wheel may make the location of the weights more important than on another wheel.
