been too long since i have seen my 750 run, have forgotten a couple things. when idling how much oil should be visible in top end with valve caps off? what should oil flow thru the tank look like? i fired her for the first time on this new F3 motor today, have bubbles in the tank, oil level rose slightly, continued to bubble a bit. eventually got wee bit of steam out of the tank opening. on the upper end, it looks like its getting oil, but i forget how much should be up there. no oil pressure guage, its out of budget reach at moment, but the motor sounded real healthy with no noise. I only ran about 1/2 float bowl of fuel, just enuff to notice all 4 firing, and my dyna dead on. no noise from top end, no discoloration i can see. please advise, if i have to pull motor out again, need to know now.
