Oily Watery Mix !!!

Hi, what's causing this watery sludge in left hand top pipe ? All the others are bone dry....
Seems a condensation problem with that cylinder OR has it blown a head gasket ?
Bike running fine other wise !!
Scooped out the gunk. Lots of it !!!
See Photo !!!

I think that's probably 'other interests' that causes that sort of thing.
Leave them alone and spend more time riding the bike.

hi Alan,thanks for the reply,your probably right a damm good thrashing required ''on the ''bike'' the goo builds up over time and splatters the side of the rear guard & number plate at highway speeds.At the moment I'm lucky to do more than 20km a day in suburbia,more freeway work & see what happens with the sludge

Roger,
Is there a drain hole for that pipe? if so, is it blocked? I recall the large pipes on the 550 at least have baffle holding plates with a groove at 6 o'clock for water draining internally along the centre welded channel and out to a drain hole. The grooves and hole easily block and then you have watery nastiness in your pipe!
Worth a look anyway,
Mike

Hi Mike,Delkevic Pipes..will look for hole,will drill my own if I can't see one
Messy sludge.I can't believe how much I scooped out....Really don't won't another episode of a blocked exhaust like last year
The baffle was carbon free,just wet & runny
