The axle being put in the opposite direction isn't hurting a thing. In fact on some bikes, like the old TL1000, this was a popular switch as it helped keep the axle tight against the adjusters while you tightened it down. Running it the factory installed way, usually had the axle sliding back away from the adjusters and you had to loosen and start over again. Since the DR650 has the pre-notched axle adjuster plates, this probably isn't as a big of an issue, but it really doesn't hurt anything either way.

Axle nut lose, yeah that can be a problem though.

Aha. So that brings up the question of why Suzuki would go to a nickel-plated emulsion tube.

And we have another one.

To clarify, this is 95 RON rather than 95 (R+M)/2, right?

Not necessarily.

Noticed the latest Motor Cyclist mag where Mark Cook wrote an editorial about his DR. Goes on to say how much he spent on it via ProCycle mods :-)

While that's technically correct, the difference is greater the more the throttle is closed and therefore the higher the vacuum that is trying to suck fuel past the exposed area adjacent to the tip of the screw. At WOT a fuel screw adjustment may or may not be detectable at all as a change in CO%.

Part throttle should be tuned with the responsible circuits, not with the fuel screw.

I was not tuning it for part throttle. I was tuning it at Idle/shut throttle ... I was wasting fuel on the over run (like shutting off coming into corners).
Leaning out produced a significant increase in fuel economy.

As you stated above, on the over run with shut throttle, vacuum is increased, sucking fuel past fuel screw needle. YMMV.

I did Colleen's DR Neutral safety mod today. YES...the Phillips screws were barely hand tight.

I replaced them with drilled stainless socket head Allens, blue Loctite AND safety wire. I would have just left it off but she likes the green light.

DON'T OVER LOOK YOUR NEUTRAL SAFETY GUYS, IT COULD BE A DISASTER.

Throttle sticking

So, over the last few rides my throttle started sticking a little, then a lot. Today it won't return on it's own. I took it apart and cleaned the bar which had some crud and rough spots on it. I used some fine sandpaper and sanded it until smooth. Put the throttle body on without cable and housing...smooth. Each of the cables moved pretty freely with good spring tension on throttle cable. I lubed the cables while I was there. Reassembled...dragging again. I took the housing off and held the cables with my hand and turned the throttle...smooth. I assembled the housing with the throttle body off of the bar...smooth.

It seems that the housing is putting the assembly in a slight bind. I can't find any spots that appear to be rubbing, but it acts like it is. No crashes or bump-ups. Bike has only been used on the street since I owned it.

Thoughts?

Cables too tight?

I'm dreading this work, specifically removing the clutch basket and the complications that come from that. I'm probably going to end up trying to yank the thing out and be done with it... unless I can't get that upper screw anyhow.
