just got back from the cup race in valdosta with son's 07 zx10. monster track, packed out with racers. only got one pass due to a problem. bike ran 5.494 at 130.08 in the eighth which is good, but shifting into sixth rider said bike leaned out, made a noise and he killed it. still ran 8.595 but mph off about 10 at 150.87 from previous runs. engine not hurt, seems to be a injector or injector signal, runs good one moment, skips the next. anyway, new best on motor. goal is 5.40's/8.40's on motor, then spray when that goal reached. good nitrous system already installed. stk. pistons, stk. bottom end, .50 hg, 08race int, stk. ex. cam, my head. pleased with progress, only 4th time ever at strip, got to be happy, but really wanted a good full 1/4 pass as i think we would have reached both our goals, but not bad at all for a streetbike.
