CB1100 Idle speed instability problem
Ok I went out and tested my 2014 DLX. Fired it up and it went to 1400 ish rpms normal cold idle. Dropped it into first and without touching the throttle let out clutch to just before engagement point and the idle went up to maybe 1700 rpms. Did this several times to verify. Let the clutch out any further and it starts pulling forward. Very Interesting.

Then I put it back in neutral and let it continue warming up until it got down to the 1050 ish rpms normal warm idle. Dropped it into first and without touching the throttle, let out the clutch to just before engagement and the rpms DROP to near 800 rpms. That's as low as I could get it to go before engagement started and bike started pulling forward.

So on cold idle a rise of near 300 rpms and on warm idle a drop of near 300 rpms by putting in gear and letting clutch handle out to near engagement point.
