Jittery at low revs

[darrsi]

4000 feels perfect to me, its ok down to 3000 and too rough below that. What rpm do you change at? I change up at 5000 (normal riding)

I just rode home from work and thinking about what you said earlier i looked at my RPM, (not something i normally do), and although i think i only went up to about 40mph due to rush hour traffic my revs didn't even touch 4000rpm!
The needle was bouncing between 2000 and 3400, but running along nicely at about 3200rpm.
So basically it sounds like you are either revving the nuts off it because your carbs are out of sync, or you are riding too aggressively, but my money is on the carbs after what i just saw on my own bike.
I'm not really one for watching the rev counter, i prefer to keep my eyes on who's about to walk out on me or pull out on me instead!
