Stav, when are you getting your bike on the Dyno at BSD? I%u2019ve got mine booked in for a dyno run next Wed as my low end fuelling is rubbish, ive got the Stage 3 Brentune flash so want them to evaluate it. Also will see if they can do 2 runs - as it currently is + I%u2019ll take the handheld with me to reset the ecu back to stock, if they%u2019ve got time for 2 runs, bearing in mind I%u2019ve got aftermarket headers on a Gen 1 so a very different set up to yours.

No idea when I'll manage to book a dyno run at BSD mate, I've been spending quite some time and money on my little Suzuki GSX-S750 at the moment so the XR has been dormant, mods wise...
It will be great to hear your experience and get BSD's feedback on their tune. I'm not familiar with Gen 1's but as far as I know the newer bikes run on wideband sensors and can be tuned to run almost exclusively in closed-loop mode targeting at set AFR.
I bet your bike is a proper animal though! Enjoy :)

Same here. By the time I roll it out of the garage and put my gloves on, it's warmed up and ready.
And I don't find this feature annoying. To me, that angry start and high rpm's fit perfectly to the XR's character.
Those who don't like high rpm's, noise and aggression, should get a Goldwing  :001:

I couldn't agree more, that such an "angry start and high rpm's fit perfectly to the XR's character."

its just an unnecessary and unpleasant noise that delays you riding off, and it not just for the first start of the day.

Unnecessary? Are you more qualified on the subject than BMW Motorrad's entire engineering staff? I doubt it.

Unpleasant? Eye of the beholder and this beholder likes it.

I enjoy the higher revving on start up and it certainly does not delay my departure either.
