[QUOTE="charismaticmegafauna, post: 235772, member: 665"] Many cooling systems will self-bleed over time -- if you work on the bike that requires cooling sys. take-apart and you refill with coolant and add to the overflow reservoir; after you ride for awhile (heating and cooling cycles) you may notice that the level in the reservoir went down.....self-bled. If you were, say, a shop mechanic, you may want to run the bike and open the bleeder to get out any trapped air so that the customer takes a bike that is ready to go and not needing any coolant topping-up later. A lot depends, too, on how much take-apart was done -- an engine disassembly introduces much air to the system. The circular 'o'rings for the water pipes are easy leakers, easy to damage on assembly, etc -- prime suspects, imo. Ionbeam's correct in saying that spray foot powder is your friend when searching for the [I]source[/I] of leaks. good luck [/QUOTE]
