Good post Matt and I agree. I ran one of my old gen 5 7 ports for a club race 2 weeks ago. We are talking an 8 gallon motor with rear ceramic and 3 gallon old con rod. Anyway it lost power in the middle of a qualifier so I pulled it off the track. I temped it and it was at 432 degree farenheight . It turned out that the glow plug came loose and it was sucking air so without ever killing the thing I tightened the plug back up and fattened the high needle 2 hours and put it back on the track. I finished the qualifier and the motor came of at 289. When I got home I took the motor apart and discovered the only things wasted were a $4.00 front bearing and the plug. It was crazy because I fully expected the motor to have no pinch left at all but it was perfectly fine.
