ive heard m any different things from many different people.. i changed my oil last sunday. however i did not take the right lower fairing off.. just kinda held it out while removing the filter casing and filter.. however i should add i wasnt intendinding on totally changinging the oil, i wanted to have a look at the filter cause i bought 2 different at the local moto store and wanted to see which one fit and mistakedly found that by loosening the casing bolts oil comes out..imagine that!!Duh! anyways putting the new filter on with the spring gasket ond filter on properly was a pain in the ass!! i acctually had my girlfriend out in the garage helping me put the bolts bak into the casing while i held the whole oil filter, spring, gasket sanwitch together..got it bak together but was prepared as farc as having oil to put in so i called my local honda dealer and he said synthetic 10w 30 sae would be fine just regular run of the mill motor oil, and he said it would not effect the warranty negativly in any way..page 117 of the owners manual lists 4 or 5 different kinds of oil you can use..hope all goes well with your oil change..oh and i have about 400 miles on my moto..
