Well, that's the point isn't it. Off idle transition on the stock bike is jerky. If you ride it like a motocross bike you'd never notice. If you ride it slow in rocks and roots (i.e. eastern mountains), it's hard to manage. I rode the same bike after installation of a power commander or the like plus an aftermarket pipe. Much better... for only $800 or $900!!! OTOH, an old-school KLX250 was far easier to make "perfect" for my kind of riding with only minor carb tuning. Plus, if you're so inclined, you can bump the Kaw to 300cc with OEM KLX300 parts.
