Coolant overflow location
« on: February 15, 2014, 03:55:15 am »
Does anyone know where the coolant overflow discharges?  Left side or right side of the bike?  Just got mine back from having the heads and ECU replaced and when I drove into my garage, about 15 miles from shop, it left a trail of coolant then dumped about 3/4 of a cup on the floor.  Don't believe it was leaking on the high speed part of the drive as there is no coolant sprayed all over towards the rear.  Odd thing is I can't get it to leak or whatever anymore.  Cleaned it up, restarted and let run till fans came on no leaks.  Drove a couple miles still no leaks.  "Leak" was on bottom right side of radiator, same place I had a small leak a few months ago that was a loose clamp.

It is now cooled off and has only sucked back up a small amount from the overflow reservoir.

Hi patches,

The Coolant expansion bottle is located on the left of the bike at the front.
It can be seen, and the level checked, by looking inside the front wheel arch.

Removal of the side infil panel ( 2 bolts and pull away from rubber grommet )
gives access to the Expansion bottle cap.
The upper panel has to be removed before the Side panel -
( 2 bolts, slide forward to release and undo the electrical connection for the air temp sensor ).

The overflow pipe is routed to the left side of the bike,
roughly in the middle, down near the side stand  :028:

You may have had an airlock that was not properly cleared out. Sometimes it takes a few cold-hot cycles to clear out air in the system. The coolant level does not seem to go up too much in the overflow tank from cold to hot.
