I agree with you on not trusting them in oil changes, but at least the oil filter is different... unless they put the old oil back in... that would be very dodgy.
I'll check the oil and will let you know, but already did 1200 miles on this one.
Yes, the bike was bought new and on the first time when the engine had to be rebuilt, I insisted for a new engine and triumph told me "we don't do that, we fix the engine and that's what the warranty is for".
I read on the internet that a courtesy bike is at the dealers discretion, they don't have to do it... I feel powerless and deceived. They took all my money and time and I don't even have something that behaves like something new.
