Hi, I have a 2017 Yamaha Ex Sport with the Tr-1 engine. I am planing to do a oil change on it soon and have some questions. I have seen on the internet that by some that not all the oil should be filled in the dip stick hole. Some people suggest pouring ½ in the valve cover and ½ in the dip stick hole. Will it not all fit in the crankcase? I am planing on purchasing a service manual and reading up on that. Another question. When I check the oil level should I screw in the dipstick or push it in without screwing it in all the way.
