Jetting? need help please

Jetting is different from bike to bike, and elevation and temperature also affect jetting. But from what you say is done to your blaster, i would think somewhere between 250-270 should be right.
 
I didn't have to get a different pilot when i rejetted mine. But if u r planning on doing your future mods i would suggest just buying a bunch of jets at once, that way you will save on shipping and already have them if you need to move up to a larger size.
