I'm about to do my first coolant flush on the bike and have a couple of questions. I'm thinking about using Engine Ice, would this be ok even though the owners manual recommends a glycol based coolant? I've also heard to flush with 50/50 distilled water and white vinegar, others say to just use the water, which do you think is better? And last, can someone tell me what the torque is for the coolant drain plug. I really appreciate any advice you can give me.
