I did mine... make a big difference.
Also have some Triumph pipes, don't remember, picked them out of the dealer catalogue..
Dont' remember what the rejet was either, but my mech took it to work (he's an instructor at Cleveland-Hopkins, Ohio airport).
Said he had more guys out there admiring and drooling over that bike than any other he's ridden to work, including my Yamaha FJR 1300 sport touring bike.
Ummm.. it still looks stock, BTW...<BG>
(Doesnt' SOUND stock, tho!
