[QUOTE="Rotorranch, post: 1240216, member: 75385"] Ditching the overflow, particularly if you're having coolant issues, wouldn't be prudent. If the radiator cap doesn't seal, the coolant will be forced out of the rad as it expands, due to heat. Without the overflow container, that coolant goes on the ground. When the cooling system cools off, the rad sucks air as the coolant cools. Result is , low coolant level in the rad. With the overflow, the coolant is pushed into the tank. As the system cools, the coolant from the overflow is sucked back into the radiator. Result is, a full rad. The radiator cap has a pressure rating. If it fails to seal at the specified rating, coolant will be pushed out of the rad easier. This could lead to the problem of your coolant leak at the cap on the overflow tank. Inspect the radiator cap closely. Worn or cracked seals, or damage, will cause the cap to bleed coolant before it reaches normal pressures. Also, the rad neck could be damaged. It should not push enough coolant to fill the overflow tank. The overflow tank is a very good idea. I wish more bikes had them. It may be a particularly good idea on 4 strokes, which are really prone to getting hot and spitting out coolant. I hope this rant helps. Rotor [/QUOTE]
