If its just exhaust then your EFI should be able to adjust properly. If cam and other changes then you would need to re-map the EFI.
Have fun and ride

:lol: he´s done his Intro! :up:

In regards to the K&N filter, YES! :2thumbs:

I know some guys who experienced hard to adjust/fix performance issues on EFI bikes when the exhaust baffles were completely removed - YMMV.

Your good just reset the efi sensors and ride it for about 100 miles and it should calibrate itself.
