1995 Daytona 1200 Puking Coolant...

Did they just overfill??
Do you see any bubbles in the header tank ? Take fairing panel off to access the radiator cap ? Do you see coolant/bubbles , do some research..... ??

 

Probably not the head gasket. Fill it again your self and bleed it properly.

 

Does the fan come on, maybe blown fuse??Possibly overfilled , the tank below seat is an overflow. My t509(different bike I know) burps coolant out when that tank is about half full,if I leave it at that it's fine.
Trapped air
Try new cap
Unless you've done many miles or raced it I doubt it is the head gasket, unless it was already suspect before. Does the heat on temp gauge go through the roof?

 

Triumph's don't like to be filled to the maximum level. They always seem to puke coolant when filled to the max but should be ok once the level stabilises as long as it remains above the lower fill level.

 

Not just Triumphs but most bikes have a naturally " happy" level and once you know it then it's never an issue.

 

I do like to keep my Triumph happy

 

Rad cap. Typical and common. Plus cheap fix, defo not head gasket.
