Phil....dowop has a speedy with pretty much the same setup as mine, tho his is an 04 and mine an 05. Plus i drilled my airbox which he hasn't. Anyway, he just put the richer thruxton needles in and said them made a considerable improvment. as much as he got removing the snorkel, which he said was quite a bit just as i noted. So hopefully they'll do me some good. Also, redbird over at RAT said he measured the TBS and thrux needles and found them to be the same with the exception that the TBS were longer. He said two 0.5mm shims shound approximate the same length as the thrux needles allowing me to closly simulate them if the TBS aren't rich enough.of course thats unlikely i suppose, but i do have the box drilled, snorkel removed and am getting a unifilter so who knows. By the way, according to that chart that shows where the different jets and all overlap, it shows the needle taper as having an impact on a much larger portion of the throttle range than shims. so i would think shimming a stock "nail" wouldn't be the same.
Deuce......yea, i saw that today while searching the archives. in fact i think i read every post here about needles there is !
