Iron 883 stalls on down shifts
Question to the mechanically inclined:
The bike stalls on down shifts. The rpm seems to dip too low when downshifting where I need to throttle it to raise the rpm (while holding the clutch down) so the engine wouldn’t die on me.
2011 Iron 883
FP3 installed (MAP: Generic 2:2 with high flow air filter)
VH Big Sucker
Bassani Sweeper Exhaust
Installed a DK Custom external breather to the air filter
Q: Can the external breather cause this problem by having too much air? Simple logic tell me that it shouldn’t cause it just an exhaust/breather and shouldn’t play a role in the air/fuel mix. Am I wrong to think this? Serious help and advice is greatly appreciated.
