I have a 2007 GSXR 1000 with 26,000 miles and just changed the oil myself. I put 4.5 quarts of Castrol Motorcycle oil 20W50 in it. I do alot of stop and go city riding and here in the midwest it does get hot during the summer. Is this weight ok to use? I don't ride during the winter.
I see that 10W40 is popular but I also see that 20W50 is ok. Any opinions?
