good to know krannie, I was remembering a bike that had a flat spot after accelerating hard but if you where gentle on the throtle it just went fine no hick up and that bike did have  a blocked squirter jet- but I'm still learning.

If your problem only occurs with very quick throttle (at rpms that are not too low) then it is your accerator pump, and it probably is clogged

If it happens other times, it can be either a rich ( blubbering sound) or lean (like a kill button) or a bad electrical connection (usually random, or after the motor gets hot)
