Doing maintenance on the bike on the weekend and notice a wire hanging out behind the oil tank, has a long probe type deal on the end with a rubber boot , worked out it goes into the head so im assuming it'd be the temp sensor for the fan , im just guessing though. Got the baztid back in after disconnecting the return pipe to the sump from the oil tank , that fkn thing was a ***** to get the clamp back on so I flicked the OEM spring clamp and used a screw hose clamp.......
