Sounds like a sidestand switch problem to me. Try holding the stand up with a bungee to see if it happens again.

My DR was cutting out, confirmed by the method I mentioned above, and a new set of sidestand return springs cured it.

In fact now that I see your original description, I'm sure that this is your problem. Passing at speed is exactly where I had the same problem as you describe.

Interesting thought, I'll check that out. I would think that it would cut out when I hit bumps if that were the case. I haven't noticed any correlation there, but it's worth checking out.

I think vibration at passing speed and leaning out to pass is what makes it happen then. Bumps didn't have any effect, on my bike.

That is odd - I agree. Do you think the petcock maybe malfunctioning sometimes?

I'd that's not it, inspect your other electrical connections, under the seat and tank. Not sure which tank you're running, but you may have a kinked vacuum line that is restricting flow intermittently.

Recently I had a similar issue, changed out the fuel but it seemed so abrupt, seemed electrical. Happened in several gears and seemed to be when the engine was under a heavy/accelerating load. Today I rode it hard on some rougher dirt and it never happened.

Given that the cut out occurs at a more predictable point ... I'm guessing it's not the side stand switch (but of course it could be ), certainly worth checking.

IMO, the problem is definitely electrical/spark related.
Start with the simple things:
Check Kill switch for grounding
Ignition key switch issue?
Check for shorting or broken wire (like in the stand switch and clutch disable area)
Replace the Spark plug wires and caps (unlikely as DR will run on just one)
Check out the coil (very rare to fail on the DR ... never heard of a failure)
God Forbid ... ECM. Best way to check is to replace with a "known good" ECM unit and pray that is not it. Expensive.

I'm not certain if an intermittent Regulator/Rectifier could cause that sort of total cutting out or not? Perhaps one of our resident EE's could chime in?

Water in fuel can cause a sudden cutting out. It really can mimic an electrical problem. And sometimes if takes full throttle (and enough vacuum) to suck the water up from deep in the Carb Bowl. (water sinks in gasoline)

Draining Carb bowl or tank worth a shot ... can't hurt!

Not likely as the ignition and charging systems are completely separate.

Gas cap may not be venting properly.

My first guess would have been the inlet filter, but you BTDT.

If you're jetted for the open airbox, just closing the opening (closer to stock), you'll be jetted way too rich.

Seat decisions

Sargeant vs Seat Concepts kit.

I need a comparison. Both in how the long term feel is and their shape / construction. How they effect seat width and height between the two would be great.

Sargents is very comfortable. But I prefer the Seat Concept seat I have now. I like a little narrow seat profile and I like the texture of the SC seat better. Just my .02.

I have no comparison to make.

My purchase (today, in fact) of my first Sargeant saddle was determined by them creating a whole new seat pan from which to build off of. Sounds like a reasonable idea to me.

Did that to no avail, but thanks. There was some remains of an IMS gas cap in there which I removed and replaced but it still had the miss. May be that pesky sidestand but it sure would seem that it would be an issue in rougher terrain
