When you notice the pinging or think you have a batch of doggy petrol do the following.Open the cover on the right hand side of the bike (one opposite airfilter cover), you will notice a little plastic box with a load of electrical wires going into it (dont fiddle with it as this is your cdi unit).
When looking straight at it on the left hand side of the little plastic box(cdi) there should be male/female connection switch (The so called switchable cdi, well thats the switch). By undoing this connection you will change the compression setting of the bike. There will be loss of power and the bike will also sound a bit like a diesel motor, but the engine will be fine and capable of getting you where you need to be.
Also dont gun the engine when the pinging starts, thinking it will go away.
If the above is a bit to much, email me and i will send you the KTM notice with pictures for changing it.
I also second the inline fuel filter and also put lady stokings over your tank inlet to act as an extra filter when you stop at "Johnny No Names Petrol Station"
