i am looking for a good starting place. i bought a 04 450r, it was running terrible. the motor is stock, has a full hmf exhaust and stock air filter. it has a 48 pilot and i put a 165 mainjet and removed the airbox lid. runs good now, but i haven't pulled the plug jet to see how it looks. just wondering if someone is running the same setup and how you are jetted. thanks for any help

i have a stock 05 stock cam and piston,with a bills full pipe hrc lid on airbox uni filter running hrc needle 3rd clip down and a 185 main with 50 pilot 2.5 turns out on air mix screw. she runs mint and flys.

your main sounds alittle lean for a full exhaust. im in ohio so im close. and im running 175-180 main (dynojet) and im using a procircuit slip on.... bump up your main alittle then mess with the a/f screw and it will rip.

05 450r, full exh., no airbox lid, prodesign air filter, 48, 185, 2 turns on air screw, I live in ohio.

put lid back on with back section cut out. running 48 pilot with 175 main a/f 2 3/4 turns with stock filter. seems to be the right combo now. thanks for the help guys
