So after yesterday's little set-back, Morrigan is wide eyed and legless (or at least hoisted up on the bike lift) and having a quick check-over. There're a number of reports of coolant leak on the Triumph Thunderbird engine, but at least there doesn't seem to be any reports of damage.
I checked with the dealership, and they only fill the coolant reservoir to the minimum line anyway, and she's still just there - she's not lost a lot, and I've now topped her up to just over minimum. She's also due her two year service, and so that's all booked in with the additional warranty work on the leak.
She's been the work for half the day, and the other half is painting the garden shed. I guess this makes for the better Blip...
