    Drastically fluctuating revs at idle

    Hi gents,

    First post, (will introduce myself shortly after this...)

    Has anyone had the issue of idle revs dropping massively from 1500rpm to about 700rpm and then increasing again?
    Doesn't seem to matter if its a cold start or not.

    I'm currently running the SC project CRT slip on, with stock ECU (awaiting race ECU within the next week). I originally thought this might be causing it, but I don't recall my last V4 doing this. Bikes only got 300 miles on it.

    Any help appreciated, thanks.

    Oddly enough I was thinking about making a post regarding this issue. I recently fitted the exact same exhaust on my ‘18 RR and flashed the stock ecu with OFT stage 2, I’ll be at red lights and the idle with fluctuate ALOT, to the point where it almost feels like the bike is gonna stall.

    Check to see if and what codes you're getting.

    Did you have the airbag off, possible you crushed one of the MAP sensor lines?
