What kinds of gains can I expect from making this change? I just want to know if it's worth it and where to get it if it is.
 
mate i wanted 54's for ages and finally got some last week, but i'm now trying to move house without selling the bike so i put them ebay today without fitting them. gutted. but there'l be other 54's i keep telling myself! check em out on the bay
 
lots more info over on the AF1 forum

not a lot by themselves but with other mods they come into their own..but why not just fit 57's while you are at it

what other mods have you got?
 
I have a bunch of mods to put on that my wife has been picking up for me while I'm on my business trip. When I get back I'll put on the open carbon fiber airbox that's in the mail from Tash at XPS, I have your collector dual mod getting done right now, and I have a Dr. Rossi Eprom mapped for the modded collector already.
 
from what i've read 54's are more suited to the early 4 spark plug motor and 57's for the later 2 plug motor. both are an improvement on standard tho. like red rat says theres loads of info on the other rsv forums
 
Is there anything else like the stacks or anything else I will need to change?
 
CER 57 TBs worked a treat on my 03, they just slotted straight on, add in all other poss mods and its well worth it

I don't think that I'm gonna inside the motor and do any porting, polishing or big bore kits.
