Hi team, I changed the coolant on the bike recently, but now the bike seems to be running hot and coolant levels dropping more frequently requiring top up. The hoses are not leaking, head and gasket OK, no discolouration of coolant. I'm wondering if there is an airlock that's pushing it out the overflow? Have checked that but still same issue, worried about it running hot, as it seems to heat up faster than normal. Any ideas?
