Hey, i have noticed that jet kits are seriously different between the years 03/04 and 05, and again between 05 and 06 ok i can understand the new kit for 06. totally new bike design. thought the 04 and 05 were pretty much identicle. dont they share the same carb.. did they change carb styles?. does anyone know what the stock main jet was in the 03, the 04 Yamha says the stock main in the 2005. is #165 and needle is NFLR-4 and a #45 pilot jet in a 39 mm FCR Dynojet cant tell me what the stock jetting is. Im sure they can but are too lazy i called them today they just told me what needle and jets come in their kit. no specs out on the 2006 and i really dont care. I have a 2004 anyone know what was stock on that so i dont have to hunt thru thousands of jetting forum posts.
