No. It's not normal to have air getting into the system as you describe. There are a couple of ways it can happen. One is that there is a slight leak so that when the system cools it sucks air in instead of coolant from the overflow tank. The other, of course, is combustion gases getting into the coolant from a leaky head gasket or a cracked head. I change my coolant every 2 years and don't have the problem you describe between changes. I once did have the problem but in my case, ('84 Wasserboxer), the head was cracked badly enough between the valves in #2 that combustion gases were entering the coolant. No problems since I replaced that head. Mike '84 GL 7 pass '84 GL Westy '85 GL Westy
