Question on a 400ex???

[thumper250x]

I just got a 416 put in my 400ex and a hot cam stage 1 and i just put an Hmf full system on it. I put a 180 main in it, which is what they gave me with the pipe and i tried to start it and it wouldnt start. I have a snorkel plug on it and i toook that off and it started right up.. any suggestions so i could run with the snorkel plug????

Ignore what HMF told you about the 180 jet. Put in a 160 (sea level) less if in the mountains. Your bike will thank you.;)
