pro design pro flow

[CSR400EX]

i have just installed a pro flow kit, and im wondering how many jet sizes i need to up. i would be out doing it right now but my neighbors hate it when my quad is started after dark:D

right now im running a 158 main and a 45 pilot without a choke stock needle on the third notch and 2 turns out on the air screw

so i just need a ball park starting point

allrite im runnin a 170 on 3rd notch on needle....i have a fmf header and hmf slip on with the same filter and billet piece...i did it trial and error and found suttin that works... put a new plug in and run it for a while then check it...the electrode or w.e. should be liek the color of cardboard if it is jetted right...correct me if im wrong ppl

actually, the kit i got came with the UNI filter. so i think that may change things. so im looking to start around 165-170. if amyone else thinks differently, let me know
