If you haven't put in a KLX needle and leaner main jet, I recommend it. The KLR main jet has a lean spot just off idle that really screws driveability then they put in a too-rich main jet to compensate. http://www.schnitzracingstore.com/catalogs/catalog.asp?prodid=4929812
It's not an accelerator pump (or a larger piston), but it does improve off-idle response.
