I'm about to replace my coolant and I'm curious if I should drain what's in it and just replace it per the service manual, or should I drain the old stuff, then do a full "flush" with 50/50 distilled water & vinegar, and THEN add the new coolant? My bike is getting up there in miles (60,000+) and I'm not exactly sure what brand of coolant the previous owner used so just for peace of mind I'm thinking I should do the water/vinegar mix first, but I'm not sure if it's necessary. What do you think?
