Just bought a 2012 Ninja 1000 with 5k miles on it. Test drive went well. I brought it out the other day for it's first long drive and the engine temp light came on. Started troubleshooting and the radiator fan wasn't working. So I replaced that. Then the thermostat housing has chunks missing out the lip that seals the system so the coolant is boiling and overflowing. I'm hoping I can just replace that and have it solve my overheating problems. I've been reading it could be a cracked engine casing, or a blown head gasket. I certainly hope not. I've been trying to locate a service manual and if someone could assist me with finding one that isn't $80 I would appreciate it! Hopefully I can get this baby up and running good to take on some fun and exciting trips this weekend.
