When I first got my 300D, it was quite sluggish at first. Turns out the Bowden cable was way out of adjustment, and by the time I got to 30mph I was already in fourth...talke about snails pace! After a few turns to make the cable a little more taught, the accelleration was wonderful.
For more info, do a search on bowden cable...maybe include the word adjustment.
