    Does your bike puke coolant when warm?

    It has happened 3 times in the last two months.  Running errands and the temp gauge goes up to the 5th bar, fans are on.  I run in to the store and when I come out this is what I find.  Once I was watching it run out the back of the motor area (where I assume the overflow hose goes).  It's only 1 bar above normal for craps sake!  Even the manual advises 4 or 5 bars is 'normal' range.  If that is so, what is this going to be my third time this summer topping up the overflow bottle??

    No, the overflow was not overfilled.  Both previous times it was between the lines or even UNDER the 'full cold' line.



    It just no lend to long trip confidence if I ever get stuck in traffic in the heat.  All three times the outside temps were 80-95 degrees F.  Just seems awfully temperamental if this is common in the summer.

    That link brings up a list of unrelated topics. 🙅
    But I will take a gander at the cap.

    Sorry about that search for "coolant leak" not the usual suspects

    I will check it out, appreciate it!

     The only thing is all three times I parked and the coolant started running out after a few moments, nothing while running. I had time to pull off and lock up helmet, lock bags, nothing. That I noticed. And it appeared to be dumping out from the rear of the engine. I will have to look more closely.

    The overflow pipe(s) run down to a point just inside the left Rider foot peg.

    When you stop riding and switch the engine off, there is no longer any cooling effect
    from the air flowing over the radiator while moving, or fans blowing when stopped,
    so the coolant can continue to heat up, and thus expand, from the residual heat of the engine.

    Replacing the Radiator Cap may well solve the problem.  :028:

    My friends Trophy started pucking coolant. It was eventually traced to a seized coolant fan, have you checked the fan is cutting in as temperature comes up?
    The coolant fan fuse should be checked first located under left hand side panel.
    Hope this helps.
