Alright so im putting on my jet kit from FMF for a 2005 450R when I pull the main jet it is a 180 stock and according to my FMF kit it says to install a 175 for a "stage 2" set-up (exhaust and filter). The largest main jet in the kit is a 180, but I read somewhere that each company has different sizes for what they call 180's and so-on. Does this sound right or is something messed up? My atv is a brand new left-over 2005 and the kit is for a 450R 2005 so im wondering if FMF just has there sizes all messed up because for the stage 1 setup it says to install the FMF 116 main jet.:eek2:
