So i've been reading this thread, and being new to customizing, i'm a little confused.....
I have a speedmaster, that thanks to Brent... I've decked out with alot of Newspeedmaster parts...(mostly cosmetic)
(performance wise) I have put on an 18 tooth front sprocket on and NGK Iridium spark plugs. i also have a Freak airbox removal kit coming.
So here are my questions, with the freak on the way i want to change out the needles since i have to re-jet anyway. I was orginally going to go with TBS needles with .33 shims, but now with all the talk of Thruxton needles i'm not sure. What is better for my speedmaster? If i go with Thruxton needles do i need shims? and what main/pilot jets do i use with them?
Current setup:
'04 speedmaster
AI removed
Stock Pipes
Stock Carbs
Stock airbox (for now)
