Way too much editing of your posts going on Griz... Next time just make a new one instead of changing what you said (optimal results with 13.5 or was it 14.0?) and adding stuff 5 times.

So you tuned your KLR with the G2 gauge then? Did you do it on a dyno? Any graphs?

If you are not very well versed in a topic, maybe you shouldn't always make these absolute statements like "And btw, 14.7:1 is completely safe. In fact, contradicting such a fact would be disagreeing with decades of hard scientific evidence regarding the internal combustion engine!". Keep an open mind man.

Whether 14.7 is completely safe depends on a multitude of factors, for example the compression ratio, fuel octane, ignition timing, induction type, etc. I would like to see you run a high compression drag racing engine or even a low compression one with 20 lbs of boost at your "completely safe" 14.7:1 on standard gas. You'd be picking up your pistons in pieces.

In case of a stock F800GS, this is unlikely to be an issue. But then again, if you were going to reprogram your EFI to compensate for the free flowing exhaust, air filter, etc why not make it optimal instead of just safe? You know, like, rich at full load and lean for cruising? More power and still get better mileage?
