It wont run 'fine' without the exup unless its tuned to do so.
My understanding with the gen 1 is that the exup helps with low down power by creating back pressure at low rpms.
With it removed and no change to the fueling I believe it would become rough and a bit gutless down low.
I'm sure it would be rideable but I doubt it would be an improvement
