Bad buzz. So no KTM tech has an idea as to why it's done what it has?

No solid clues, just lots of speculation, oil pumps were fine, looks like maybe the oil jets maybe got blocked?? Who knows,

Bugger. So I gather it's a one off...not like they're doing it all over the globe?

When i pulled my RMZ appart i thought, it was quite strange that the cam spun directly on the Alloy Head instead of being supported by a bearing, I thought it was quite cheap and rubbish. But It seems KTM do the same.
What's the reason for this?

Most modern 4 stroke singles just run the cam/s on a hardened surface it works for early sl/xl Honda singles and how many of those are still being ridden-heaps and they just use a oil strainer not a filter.
Have seen many a 4 stroke with a blown engine a few the conrod snapped smashing the cases, barrel, bending valves only salvageable were the gearbox and clutch, over $6g in parts. A mates RMZ450 010 blew its gearbox 2nd-5th $2g in parts from the states. Another mates CRF450 did its gearbox at 35 hrs he got it fixed sold it and got a YZ250 end of problems.
A MX bike will have a design life be it 200 or 300 hours same as your fridge/washing machine.

Are you fixing it or selling it off in parts? 2011 350sxf are going for around 8-9g so 4g in parts might not be worth it.

Wonder if you'd do alright out of it stripping it down.....but i spose if if they are selling for around 8g you might get 3-3.5g for it as it is?

That's a scary story and I thought KTM would have had their stuff sorted .

Been thinking about a new $4T but I'll hang on to my old 2T for sure now.....
