Just realized i posted this in a for sale thread for a water tank....

im not claiming to be correct here, but i think if the headers were glowing due to a lean condition, the valves would be toast. I'm guessing fuel burning in the headers is why they were glowing. you cant run a lean engine hard and live to tell about it generally.

so, what makes you guys think its lean? im concerned if you start leaning it out trying to fix the problem it might burn something. Any reason not to fatten it up first and see if that gets better? does it have O2 sensors?
