Yes,i have to agree,but this still doesnt account for misadjusted oil pump settings-i couldnt believe the oil my f5 was using compared to all my zr500s-my f5 was using a quart and half at 100 miles,this means i would be getting 200 miles to a tank of oil,thats plain sick!!!!Was using twice the oil as my zr500s-took it back to dealer to get updates,said my oil pump adjustment was way off from factory,since then its perfect-after reading about it in the 2003 performance manual and double checking it myself,the oil pump marks at idle and full throttle are exactly where they should be.Personally,i think with these new motors,cat just wanted to be on the safe side from factory-same as jetting on f5s,cats running them rich as usual-98 zr500s started out with 360 mains from factory,by the time 2001 came around with apvs down to 330s from factory-now on the f5s 380s from factory,a few years will be down to 360s,cats just covering there asses-just my two cents-scott
