Couldn't say for sure but 29mm is a little small in my opinion.
You will get very high gas speed through the venturi and may need to down jet them, making the overall set-up un-rideable.
34mm or 36mm seems to be about optimium from approx 1100 to 1300cc with a road setup all things being equal.

What air filters do you have and i guess we are talking about 34mm CV's?
Is it standard setup for the top end; cams, porting, valve size and valve timing etc etc etc?
Which exhaust is it?
Which ignition set up do you have? 'S' or 2000 or another?

Roughly; CV's work best with standard airbox give or take. You can get a K&N for the standard airbox. Radical or incorrect valve timing can supress inlet vacuum giving problems with flow characteristics, it can help to set the two inner carbs a little richer, you can 'pre-load' the springs above the slides to stop them opening too quickly (not recommended) slower opening of the throttle often results in increased power delivery, a weaker mixture can give better power delivery also (right up to the point of detonation) but care is needed here, air leaks around the inlet stubs are a common failing, and so it goes on.

What are the specific symptoms of poor performance you are experiencing?
