Technical Jetting Question... Yeah i know...

[TripleR400]

Alright so i got a full system curtis sparks exhaust... They recomend 155 main and 45 pilot(45 sounds a little rich to me) which i have put in... My bike is a stock 05 w/a uni filter (no lid) and im just wondering if not turning my air fuel screw will do? Do i need to move the needle? Any help will be appreciated and yes i did a search for two hours...

45 sounds way to high.id throw a 42 in it.the air fual screw is like the adjustment for the pilot jet.you may need to move the needle one notch.

how it running?bogging alot?popping on wot?
