Recently bought an MC18, great bike, but its carburation is lumpy to say the least. The bike's been stood for a while so it's been treated to a new battery, plugs, fluids, a carb strip and intake rubbers, yet at times it feels as though it's being starved of fuel before picking up again. It normally does this at 9000rpm - not all the time, it will pull through to the redline, just sometimes, and it's pissing me off to say the least. When it running fine it flies, in every gear.

It's not seizing, but could it be the PGM control box? Any help would be appreciated coz it's driving me nuts.
