if you didn't see this in the "crap-broke down" thread, here
it is again-and thanks to Hepworth for pointing it out! :
Look above and between the wheels ( best seen from the riders left side)
and you can see a major hose coming from the radiator that is
resting against the housing of the fan. Look to see if it is cutting
into the hose. Both of our 500s hoses were in the process of being
cut into. Yours likely is as well. Mine was close to being cut through
and I would have been spewing antifreeze soon.
If so, find something to get between the two items that will prevent
it from further damage. You can see in my photo the curved piece of
heavy plastic i wedged in there. Easy fix.
