Many thanks J.D
Mine is a '19 spec bike, the low oil pressure was apparently caused by the filter, this was changed and apparently all is now ok, no mention of why it caused the problem, something I want investigated and an assurance no top end wear has occurred.
The leak was from the top radiator hose and was leaking from within the wall of the hose, kind of in between the layers, so it would seem a manufacturing problem, as opposed to the seating of the hose. The bike is still with the dealer as apparently there is a 2 week lead on the hose.
Got to admit I got a bit pi**ed with the dealer and after a bit of searching found the email address of KTM Austria's MD, filled him in and then all **** broke loose at KTM UK and the dealer and now they seem to be on the case!
Got a loaner at long last, which in my opinion should have been offered straight away, without me having to kick off!
