Hi guys - the good news is that my 999R running problem was apparently a fuelling issue with it suddenly running extremely rich !!
(like a pile of s**t !)
Hats off to the boys at 3X Mcycles - they fixed it and it runs fine now !
It also had to have the safety recall check on the oil cooler ! - if you've got one with a KTM cooler - make sure you get it checked !!
