I own an 07 gsxr 1000, i've been having overheating problems for a few weeks now and i would like somebody to give a north on where to start looking to fix this issue. Everytime i fill the radiator and the reserve, and i turn the bike on, the antifreeze comes out through the overflow hose in the bottom of the bike as soon as the temperature reaches about 215 degrees, at this point the fan does turns on but the temperature keeps on raising. what do u guys think ?
