I literally just bought my first bike, got it running again yesterday. Cleaned the fuel injector, cleaned out the gas tank as it has been sitting for a few months with ethanol gas (never again), and got her running and gave it a fresh oil change. Rode it to work this morning with no problem. Other than when I stopped got off my bike and seen this. Clearly a coolant leak somewhere but I'm not sure where to start. Maybe by swapping out my o rings on the radiator hose? I'm not too sure please help thank you. #motorcycles source
