Before any "bolt on" mods to my 400 I could run WFO and not overheat the engine. After adding WB E pipe, WB Rev, Dyno Jets and K&N I have overheating problems. (I think)
Main is a 170, air lid off.
While crossing a salt flat south of El Golfo, wide open, my bike died. I waited several minute and restarted the machine. 5 miles later the same thing, this time 5th gear and 1/2 throttle.
I pulled the plug and it is black. Not a wet black, but a very dry black. There is some oily looking black stuff on the threads.

If I put the air lid back on, will that fix the problem? From what I have read i'm running lean? Does that mean reduce air intake? or install a bigger main jet?
Thanks,
