I depends on the pipe, if you fit a 35mm carb to an engine that has a low/mid pipe you will defeat the low end of the powerband. The stock 26mm suits that application fine.
If you have a mid/high pipe then the 35mm carb will suit it just fine.
Broad range pipes like the Toomey B1 will work very well with a small carb and the highs will be somewhat better with a larger one.
The V force reeds will give a much snappier throttle response if married with either a large or small carb, a good investment.
