Since a lot of my riding thus far has been put-putting from stoplight to stoplight in the city, it still runs hot-ish, as I described earlier.  Maybe that's just the way it is; however, I am considering changing the spark advance in the above table to zero up to and including 4000 rpm and 40% throttle. This is where most of this slow hot riding is, so maybe it will run a bit cooler there as a result.

While there is a correlation to ignition timing and heat, it's not the main determining factor. 99% of modern FI vehicles run a hotter temp (Normal Operating Temp) to assist in cutting emissions and maintain "complete" fuel burn. The often lean condition on our bikes due to high AFR's *probably* causes the most heat – more than acceptable timing increases I would think. Timing has a particular influence over EGT (exhaust temp) and temp in the head, but don't expect lowering the timing to drop the temp 2-3 bars under normal conditions. The cooling systems are designed for the higher temps. The super high temp fan switch also plays a role, which is why many ADV riders change it out with a lower one (185-190º suzuki IIRC). And if you're put-putting around, there may not be much air moving through the radiator.

If it feels good, I'd say watch the plugs and leave it be. That mid-range punch you feel is likely the timing increase.
