Jetting a 440

[gotsand400]

i just did a 440 kit and wanted to know
what main jet everyone was running. I will
be riding at about 4000 ft. with no airbox lid.
Any info would be helpful, thanx

any other mods? pipe? whats the temperature?

I have the 440 kit with hot cams stage 2, and pro circuit
slip-on. Temp should be around 70 and up.

i would start around a 160 keihin mainjet.
