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!

We have a jetting database on the site you can check out. What main jet are you using, DJ or Mikuni? Stock needle?

If all jets are clean, and you dont have an intake leak, you should be very close if you are at low elevation. That stock needle probably wants another size up on the main compared to a DJ needle. I would bump it up one or two sizes on the main, see how it likes it.
