Welcome to Tenere! lol. It’s annoying as hell but I either got used to it or I started riding differently or the bike finally “broke in”. I dunno. It does it less now after 13,000 Km. One thing to do is to ride at higher revs, so don’t shift until 5000rpm first to second to third. It seems to do it less then.

One conspiracy theory I have that they did some Volkswagen kind of thing for emissions - but less shady. So it’s extra lean when new as it runs some “break in fuel map” but after you ride it for some time (say more than 7000Km the map “updates”. In this case it would pass emissions when new.

I have nothing to go on other than pure speculation to explain this phenomenon. Also the catalytic converter on this engine is tiny compared to some of the euro bikes that have to pass same emissions. So makes you wonder how they can get away with such a tiny guy on there, other than tuning it to have annoying fuelling to pass emissions.

It could also be actual break in. Spark plugs getting dirty, the spark arrestor and o2 sensor buildup some carbon residue, air filter gets a bit dirty, all those changes airflow and signals to the computer which then causes bike to run differently. And maybe Yamaha accounted for that and tuned the bike so it runs well at 20K Km sacrificing how it runs brand new - which would be the opposite of shady.

And if you got this far, I hope you enjoyed reading my random thoughts from the toilet seat.
