Did a show last week, and overheated the bike for the first time....puked coolant out all over the place.didnt have any coolant so replaced it water. When i got home, i flushed it, and went to the bikeshop to see what they reccomended for high-temps. and everyone seems to agree on waterwetter& straight water. Tried that, and didnt really notice any diffeernce. my fan runs whenever the bike is on. Now once i ride the lot for 20minutes or so, the bike starts getting real hot, and then starts to bog and have a shitty idle because of being so hot (i assume)
Anyone got any tips/tricks for keepin the 03/04 636s from overheating?

 

its prolly your water pump or thermostat goin bad homie

 

check pump and thermo stat, and wire up a second fan, that'll help too
