    Lost #1 Again

    Please give me your opinions. #1 has 90 lbs compression. Nice dished out section on top of piston. I've lean seized several times now. Have had injectors cleaned, controller sent to Rive for testing, added fuel pressure gauge. Settings 7/9/4/6. Still looks lean on 2 & 3 to me.
    This happened after an extended run @6000 rpm
    '03 with v force reeds, 3 degree key, race filter, d plate , free flow, etc

    I'm going to go out on a limb here and say air leak. Those look really lean to me. Did you pressure test the motor after installing the reeds?

    I pressure test before I assemble. Bought the kit from Lowell last year. No leaks

    Talked to Lowell today. He questioned my cross-over setting. The high speed red circuit has been set to come on @ upper 5000 rpm range, Lowell said it shouldn't come on until closen to top rpm, around 7000.
