Sounds good I think the occasional pop and the raspy sound is valve springs. Never had the opertunity to go inside the sym motor, but mine sounded just like that and cleared up after the springs were changed out. You prpbably won't get to but 82-8500 rpm with wheels on the pavement. I may have asked this before but do you know if you have the 2 or 4 valve head? You looked like you were cold out there. It didn't feel cold to me LOL
