Sticky this??? Jetting!

[400eXr1d3rZ]

Okay, I was looking in the YFZ450 section and I saw they had a thread for jetting stickied, now if we had one in the 400ex forum, people wouldn't be posting a new thread about jetting everyday. So can a moderator please sticky this?

Post your jetting!

White Brothers E-series (with JE 416 10.8:1 piston, stg2 hotcam, twin air filter and cometic gaskets)

Sea level
165K main
42pilot
needle one notch DOWN from stock
air/fuel screw 3 spins out.

whats a good starting point for jetting when i have a 406ex with a wiseco piston piston,hotcams stage 1,hmf full system,and a k&n air filter.o and i live near atlantic city so im probably near sea level.(don't know exact feet)

Start out with a 40 pilot, 160-162 main and lower the clip on the needle one notch.

My Setup-440 Stroker 11.3:1 comp, Stg 3 Hotcam, P&P head, Stock carb-no choke, Slip-on, K&N Filter-No Lid.

42 Pilot, 175 Main, One notch down on clip 2.5 turns on the screw. Works great from sea level to about 3000 ft. Although at 3000ft it's running a bit rich.
