Hey guys was curious if anyone has ran a 440 or 434 big bore kit with a hmf exhaust and header. If so what jetting would you recommend at sea level? Tried 155 main 27.5 pilot and it seemed to be still too lean. Any help would be appreciated!
I live in ky my elevation is around 400ft I have a team Suzuki yoshi slip on and a uni filter air box lid on, snorkel on ( no point of removing it I’m not racing it) but I just want to know what jets I should run and where my needle should be thanks.
