[tmccaughin]

what is your elevation and are u running with no airbox lid

[prepracing]

anywhere from 155 to 165, good luck:D

[JukeU25]

no.. mine didnt come with them.. yes im keeping lid on b/c i ride in mud alot... and elevation im not sure but i live in east tennessee if that helps anybody... ???

[JukeU25]

yeah and does anybody know the best way to run that with ... the silencer in... how many plates on.. or everything off????

[tmccaughin]

i put dinojets in my 400 and the main is 146 and the air/feul screw is 2.5 to3 turns out and im below 3000 feet obove sea level

[B-rad D]

how do u like UNI air filter and the megamax 2

[JukeU25]

uni was great on my old cobra pipe but i gotta rejet it now but im sure the megmax will be great....??? so fur sure 146?? will it matter if its between sizes as long as its close????

[prepracing]

just an FYI - remember dynojet sizes are different than other jets sizes(khein)

[JukeU25]

yeah.. I got the right jet in and man it gives it a good boost... but there is a little lag in my throttle response can anybody help me with that????

[plkmonster2]

Use a 152 main in summer, or a 155 in winter. run a 42 pilot, with the screw 2-2.5 turns out to get rid of the bog.

[Jonas]

Ya, about what monster said. Don't run a 146 main jet though, unless to are running at really high elevation.

[JukeU25]

hey thanks guys.... I was messing with my screw earlier when iwas rejetting and i dont know why but ill have to get it bak to where it needs to be... well thanks again

[MR.BIG]

With no airbox lid you should be at about a 160 or 165 main jet.
