Jetting question

[reconmaster]

j/w do i have to rejet my 300ex if i just put in a uni air filter
i got a jet kit fromK&N/Dyno Jet that for it to. I plan to use it when i get a pipe.
if i do have to jet it whats the best main jet size i gog 106, 110, 114, 116, 118, 120, 124, and 128.
Thanks for the help

for the main jet size,follow the dynojet instruction sheet

I think that you will better to rejet it because with a Uni filter you will run lean because the filter will increase the air flow but with the same main jet

it says 4 stock pipe go 114 if i'm below 3000feet

Stage 1 : For midly tuned machines using the stock airbox with stock or aftermarket filter.May also be used with a good aftermarket exhaust system

Then I put the stage 1 in my stock 400

well i ran in2 a bit of a problem here the jets are not long enough and the 1 thats on it is a 122main jet. My question is whats the factory jet size for the 300ex and could this be a stock 400ex carb on it
when i bought it it came with this jet kit never used

If you have the Dynojet kit, the jets require an adaptor that is in with the kit. Atleast the kit for my 400 did.
