It's a personal preference. I'll change oil after few spring rides and filter is good for a 2 oil changes. You can leave existing oil and change it during winter Something telling me that you will not let your bike sit in the garage without turning it on for a few monthsSo I change the oil and filter, keep the bike parked over winter, in the spring I chuck all of it out and replace? I better pick up an el-cheapo Fram then lol.
