But, like many automotive systems, it may be possible to design a reasonable MC limp-back mode for situations such as failure of the throttle position sending unit.

Same old new vs old technology arguments. You know, points and condenser vs electronic ignition, carbs vs EFI etc, etc. New tech always wins out and after a while none really remembers how much better the old tech was.

This was the parking lot. You can just BARELY see my bike hiding behind that 4runner.



Yup, I was the only bike there...

Well, IMO we still have a long way to go before we reach the "after a while" point as far as reliability of fuel injection and fancier electronic gizmos on dirt bikes go... KTM doesn't still run carbs on their x00,000 $$$ factory rally bikes because they handle elevation and temperature changes so well...

But I sure was impressed that the Bergs start and run perfectly from 0 - >20,000 ft without having to touch anything! It's the future for sure.

I hope you guys on the east coast are staying safe and somewhat dry...

Thinking about going out for a hurricane ride in the AM.

That looks like the future is here already. What the heck is taking KTM so long? Oh, I forgot only paid $12,000 for my 690. I am unworthy of the better system. .

On another note: The current Dakar 450 KTM are fuel inj.?

Nope, 450 Rally is still using the good old 41mm Keihin FCR-MX pumper carb.

That's fn funny.

LED aux light assist. These are VisionX mounted with aluminum angle I hit with sander and sandwiched with the hand guards. Don't drink much juice, big lite light. Reach into junior high wiring behind candle container to tap harness connectors - ez pleezy.

Holy crap, those Fairyland dealers like to bend you over!

I drove to Boston this morning to help dyno my 690 and get the base maps built. The results so far are excellent! The throttle off idle is very, very crispy. I've never had it feel that good with TuneEcu or the Vortex, it was amazing.
It made 57HP at 6500 RPM but we encountered a strange problem where the Pulser coil voltage gets a little crazy and throws the timing signal off a bit.
We found the problem, so its getting more dyno time tomorrow to finish up the map.

The power and torque curve is really smooth and parallel, right to 6500. Once the pulser is adjusted, it will pull to redline cleanly and make even more power. My best guess is 60-61 HP at the rear wheel tomorrow. The exhaust is a Q4 with the insert and the simple UNI pod filter, I wonder what we'll make with an open exhaust The motor is bone stock, no cams or big bore kits.
