HRC Needle and Jetting

[Ex'rMike]

I know this has been beat to death.... Sorry Guys. I need some help. I just bought an 05' 450r and made theses mods to it.
-Cut back section of airbox
-Drilled out crankcase tee
-Cut out spark arrester
-Modified intake tube
-Installed Uni Filter

I have picked up an HRC needle and some jets. Can you please give me an idea on needle clip postion and jetting. Thanks

ALL I CAN TELL YOU IS WHEN YOU GET THE HRC KIT IT IS JETTED TO A 185 MAIN. BUT THE KIT COMES WITH A DIFFERENT CAM SO I WOULD TRY A 150 MAIN TO START. WITH THE NEEDLE I WOULD START WHERE THE FACTORY HAD YOU OLD ONE. WHY DID YOU DRILL OUT THE CRANKCASE TEE? YOU WILL HAVE TO KEEP TRYING IT TO GET IT RIGHT. GOOD LUCK

go with a 185 main, just like in the kit. cams don't effect your jetting
