450r jetting with hmf s/o??????

[hendrix450]

i have a 450 with a hmf slipon and i am running with an open air box and i am figuring out that jetting it is quite teadious. i started with a 170 and the low end felt really weak and plug was white. then moved up to 180 and the throttle response was a little slow and the plug was a light tan. i was wondering what other people were running in there 450? i think i am going to move up to a 185 and see what happens. is there anything else i should change beside the main? thanks

Buy the HRC jet kit from your dealer for 30 bucks.

I'm running an '05 TRX450R with HRC kit, JE 13:1 piston, and HMF slip on. I think pilot is a 48, HRC needle in middle position, and 185/190 main.

HMF slip on, 175 main, HRC style cut lid, uni filter, and boy does she rip!
