I have a 2007 hayabusa, first ride after purchasing ran hot on me. Reservoir was dry, couldn't see no fluid inside the radiator. Afterwards I pour engine ice directly in radiator and fill the reservoir. Notice reservoir was empty today I refilled it ( didn't check inside radiator ) after 15 miles of riding reservoir is empty again. I could see leaking but not 100% sure it's coming out the overflow. Any suggestions? Plan on taking to a shop but everything is booked up for aleast 3 weeks near me.
