Hey All... I got this 400ex a while ago and ive been working on it in between everything. I was trying to get the jetting dialed in but I could never get it to run just perfect. I found out my header was cracked...

So... I had a friend weld it up for me.

Then I decided to wrap it. I used the hit-temp silicone paint and black 2" dei exhaust wrap.

In an attempt to keep the heat down, I fitted a small transmission cooler behind the front frame rails. Its plumbed in-line with the factory system for now, but im thinking about re-doing it like the four stroke tech kit and adding some better mounts.

So after new crush rings and a fresh plug, I got to work on the jetting again... The previous owner cut the baffle out so it flows a little better and i ground down the header welds. Right now thats the only mods and im using a 40 pilot with a 152 main fuel screw 3 1/4 turns out and I tested the plug at idle-1/8 throttle, 3/4 throttle, and wot. All 3 tested very very close to this color, tell me what you guys think...
