Hi,

I can't help you with drill bit sizes, but I can point you toward some general guidelines. For CV Carb jetting, see the very informative article at Factory Pro. Also see the carb jetting tips at Motorcyclecarbs.com, Inc.


Thank you for your indulgence,

What pods? K&N or something different?

You are probably better off getting a DJ kit. The holes you need are going to be in the range of 130's.

Pods and a Kerker? Sounds like my setup before going big. Get a Dynojet kit and I'll help you set them up.
