HI i recently changed my oil about 100 miles ago at the 3800 mark and put in 20w 50 because thats what the dealer recomeneded i put it in the bike ran a bit slower so it seemed to me so i took that shit right out 100 miles later and put in spectro semi synth 10w 40 i put oil in the filter and made sure i used 3.6 liters and put the rest of the oil in on the right side i start the bike and the oil light come s on. i figure i need to let the oil pump let the oil work to the top of the engine. i can hear the lifters knockin and let idle for a while then shut it off and turned on the oil wont get to the top of the engine i put the bike away and havent started it in fear of hurting something any advice is greatly appreciated. and i know i have the right amount of oil and everything. anybode get any loud noise after oil change or light on??????????
