and for the stalling issues the throttle sensor has been replaced and been tested for 2 days and has not re-occurred just yet.

thanks for the opinions and suggestions all.
Definitely possible, Makes my original diagnosis seem dumb. I don't know why I didn't think of the simple first. I suppose when I am hit with so many technical questions my brain starts to think of the complicated first. Which goes against everything I was taught as an apprentice.
I usually go for the simple first. I had an instance once where a guy spent hundreds of dollars and went through 3 bike shops to diagnose a bike that would run great for 5 minutes then stop and not start again for hours. He brought it to me and I was the only mech that thought to remove the fuel cap straight after it stopped. I got hit with a massive hiss and pop sound as the tank was released of vacuum. Found the problem, a $10 blocked fuel cap!

I'm glad you got it fixed. Engine noises will put me in an insane asylum.

typical 690

I've had similar sounds, we need more locktite than the average jap owner

On the issue on stalling.. there's an understanding that getting a KTM mapping that's made for a kit containing different camshaft could cause this. im quite sure i almost fixed it by changing battery
I've read somewhere about injectors and voltage drops, but i cant produce article to support my statement.
