Hi there my GFR's coolant in the radiator is boiling(bubbling) I'm not too sure why...any ideas anyone? The thermostat was unplugged from the head before I went out...I connected it before I rode the bike. Speedo,temp gauge and rev counter not working. A red oil light and neutral gear light were showing up before when you turn ignition on but not now they do not illuminate. Any help would be appreciated.

Air lock
Water pump fail
Cracked liner
Leaky head gasket

Hang is this not the Mito section.

Either leaking and not pressurising so it boils or the combustion gasses are passing the head gasket most likely.

Thank you all for that...I used a gunson compression tester but only finger tight...only reached 83 psi,so does that sound like head gasket gone? It seems to run ok,I just got it started for the first time and rode for a few mins up to the shop and back.
