Rough idle on 2004 1200GS

[GS Mark]

Hi all. I fitted a new clutch friction plate to my GS last week and since reassembling the bike it has developed a really rough idle. I got the Twinmax out after my run home from work tonight and sure enough, it's leading on the left cylinder at idle (constantly between 0 - 2 on fully sensitive setting). Slight lead on the right cylinder at 3500 rpm which I'm sure I could adjust out on TB cables. I've put a video clip on Youtube showing the issue - https://youtu.be/5Rh55MT3_hM

Is there anything I can do about the idle speed? Something obvious I might be missing/have disturbed having dismantled bike for clutch refit? The only slight suspicion I have is that I adjusted the valve clearances a couple of days before the friction plate went - I'm sure I did them correctly but if they were out would it cause such a rough idle?

I don't have a gs-911, but apparently this can be used to balance the TB's - anyone near Sheffield have one?

Thanks, Mark.

check the throttle cables are seated properly in the junction box and at the throttle bodies.

I had a similar problem with my 2011 bike. I connected it to my gs911 and discovered that one of the idle actuators was not functioning. A quick check on oem to see what the idle actuator looks like, then on examination I saw that I had somehow dislodged the canbus connector which feeds the back of the actuator. Once the connector was reseated all was well.
I don't know if this helps, bearing in mind the model difference between our bikes, but check your idle actuator.
