Trumpet Daytona 675 muck in cooling system expansion tank

[I am Chad]

Anybody had any problems with the Daytona 675 getting a deposit of muck in the cooling system showing in the expansion tank? The bikes only 4 weeks old. Its not oil thankfully.
I spun it round to the dealer this morning and was basically told that Triumph are well aware of this muck showing in the cooling system expansion tank and its nothing to worry about.
Appears they used to carry out a flush of the system under warranty orginally but Triumph now have investigated it and said to the dealers its not an issue unless the bikes cooling system is causing problems eg. overheating etc.
So basicaly the dealer wont flush the system out as it would not be honored on warranty...bit poor really.

Looks like i will have to flush the system myself, anybody familar with flushing out the Daytona 675 cooling system?

No idea if they do this in the bike world but in the car ive heard its not uncommon for dealers to put what is basically radweld in to ensure that the new hoses dont leak during their initial expansion.

so it could be that, maybe

Don't worry about it. Go onto this site www.triumph675.net and go through the forums. I studied it all when i got my 675. My coolant was kinda brown when it was swapped at the 6K service. It's possibly deposits from the new components. Whatever it is, it doesn't cause any issues.

One thing to keep an eye out for is any coolant leaking from above the expansion tank, as there is an elbow there which can crack. Rare, but happened to me. Dealer (Jack Lilley) were excellent as always, replaced it, and the plastic parts it stained, gratis.

Not that it helps you too much, but I have had no troubles with mine so far.
