When I'm riding my 79 kz1000st I get a loud screeching noise whenever the revs get above 7000, it is especially loud and screechy in the higher gears. It only happens when my wife is on the back with me. :woohoo:
But seriously, I took the carbs off and reset the fuel level again ( 1 of my header pipes was starting to blue) and also went back to the stock 15 pilots. The bike was running great before but is running freakin awesome now!
