CB1100 Idle speed instability problem
Guys, update. My lazy butt finally got the resistor mod done.

I've been riding with two 330ohm 1w resistors stuck in my IACV plug for about a week now.
My experience:
On startup, bike kicks on, and has a considerably lower idle than before, around 900-1000rpm. Prior to the mod, it was consistently idling at 1200+rpm, even after warm.
A short ride around the neighborhood for a couple miles, the idle does not change and rev high, and still runs like a normal motorcycle.
Once I get some miles in (I commute 20mi both ways during the week), and the bike heats up, it starts running just about the same without the mod, revving high while in gear with the clutch pulled in, revs ramp up when letting the clutch out, and only drops the revs when putting the bike in neutral.

I'm not sure if the resistors are heating up too much and losing their ability to..... resist?

I haven't tried any other resistors yet, as I wanted a baseline on how this would perform over a week of riding.

So unfortunately the resistor mod has not 100% fixed my issue, maybe I'll bump up the resistance and see if there's a change.
