This past spring I rode my 89 VR to ST. Louis and back, while out ther had an issue with coolant leaking overnight. Attributed to different metal types cooling at different rates. Temps here have been pretty cold, but warmed up some today. So when I was in the garage today there it was again that puddle of coolant!!!! , without even having the engine hot!!!??? I rode that thing all summer with no problems. Help!!!!!!!
