I just had a new motor put together for our big open comp. We had a practice session 1 week before the race the motor seemed to run fine. I only ran 15 laps. Wanted to save it for the race. Well we went out o wheel pack and the motor didnt sound right. I pulledin and pulled valve covers and noticed #6 exh. wasnt moving any where near the rest ...anyone have any ideas... We broke it in 3000rpm for 20 min..

check the oil. if it is really dirty, you most likely have a flat lobe.
