low rpm stumble

[IanDark]

So i just traded my 06 ducati monster 620D for a 2007 xb12r in black and red. Loving the bike but it has the low rpm stumble and miss ive read about on here, i heard harley had released a fixed ecm map for this and was reflashing bikes with it, does anyone have this map that just fixes the stumble and works with stock exhaust? Ive found the race maps but dont think i need that until i get an exhaust which will be after winter. let me know what you guys think. Damn this bike is cool if it ran right at low rpm it would be even better

Here she is.

how low is the rpm when it hesitates?

what is your mileage and setup?

 

[IanDark]

its 1000-1600 rpm or so. Bikes got 12k on it and its all stock, gonna do plugs filter and breather reroute soon.

so i was reading more about the ecm and how it runs closed loop up until 3000rpm then it opens up. Makes sense that the bike runs crappy under that rpm at this altitude. 9k+ elevation. Now im wondering if im running lean or rich, some logging will find that though. Anyone else at high altitude with issues similar?

9k+???

 

[IanDark]

yeah 9000 + FT altitude/elevation.

to update this issue, i did a breather reroute, upgraded to uni air filter, reset the tps and adjusted the idle properly, 1050-1150. Bikes ALOT more responsive and the stumble is pretty much non existant. Next is logging and tuning for my elevation.
