[QUOTE="Coach in ND, post: 144960, member: 22352"] Here's what I did on my new 400SX. 14-54 gearing for motocross 13-52 gearing for off-road Pro Circuit T4 Exhaust Jetting Specs OCEMN needle, 3rd clip 168 main fuel screw 1 turn out I installed an Emgo filter on the crankcase breather hose and placed it under the fuel tank. My dealer had a plug that fits right on the spigot on the card that the crankcase breather hose fit on. Putting it under the fuel tank would be a better idea but would require a longer hose to reach back that far. [/QUOTE]
