Blaster stock jettings and mod pipe

[waveblaster146]

I am getting a factory b mod pipe put on my stock waveblaster. I am not sure if i have to change the jets or if they can stay the same

Can anybody tell me wat the stock ones are and what they recommend for that pipe?

Factory pipe gives you jetting recommendations in the instructions and actually supplies you with the jets if you buy the pipe new (good luck with that). They say to use the stock needle and seat with a diff spring (also supplied) but some folks advise getting a larger needle and seat as well to lower the pop-off even more. I followed the info in this thread and it got me pretty close:
