Thanks for taking this up. I don't consider it any sort of privileged information to be in possession of the way that it's been amended? Surely they should actually be thanking you if anything?
I’m sure that updating the owners and service manuals was just overlooked - someone screwed up. I suspect Tritun will be updated and also the online owners manual which owners can then download. This “reactive” solution is clearly insufficient and I feel that a more proactive approach is needed. Take an owner who decides to change his oil, follows the handbook instructions and screws up. How would he know that there is an updated version online and the oil change procedure is wrongin his OEM handbook?? This whole debacle has left me deeply unimpressed with Triumph if I’m honest!!!
