It had been 25K miles since last spark plug change (I know, shame on me) and TBS adjustment. It makes sense to me to do them together since to take advantage of being under the tank.
I was surprised how much difference there was between the cylinders.
Before adjustment:
I took the photos with rpm set at 2500.
After adjustment:
Yes the engine is running in this photo. Only took adjusting cylinders 2 and 4 to achieve this.
I didn't take it out for a ride to see if I can't detect and performance (smoothness) improvement.
But I must say I was surprised how out of sync it was before the adjustment. Previous times the spread was noticeably tighter.
