It looks to me like the hi/lo function of your new lights is a type of diffuser, like those flashlights that 'focus' to intensify the light at the center or to spread the beam wider. Your new lights are much brighter, more concentrated and focused in the low beam pic, and softer, more diffused in the high beam pic.
Is it possible that your hi/lo wires are reversed? maybe they were mis-labeled? I think high beam should be bright and focused, low beam should be softer and wider.

Oh, ya, BTW, you might as well just run your (now practically useless) h4 on the 5w park bulb as much as possible and save 60w for some hot grips and a heated vest.

A little lights update. I took Ernst for a weekish long trip out to Montana and back recently. On my first day, on Hwy 395 somewhere north of Fox OR I caught up to, and passed, a guy on an FJR. Now clearly, he wasn't trying as an FJR is probably the bike you want to be on when you absolutely positively have to be there overnight. But when I stopped for gas in Pilot Rock he pulled in and we talked Airheads for a bit. Nice guy--also an Airheadist when he's not on the FJR. His words as I remember them: "Those lights filled my mirrors!" He asked what they were and I gave him Google search info that would get him to this thread so he could find the link. I've been very happy with them so far (no real night riding yet as I avoid that) and it was great to hear some confirmation from an outside observer.

Ernst has been sitting a while as I've gotten Edgar sorted. Partly because of this:

Image

I parked Ernst at the end of June and took the final drive to Hansen's for new seals, and as it turned out, new bearings. That took a while as they rebuilt their FD fixtures but Craig thinks they're doing better work with better tools now. Here's what I got back:

Image

I cleaned up the surrounding area and got Ernst back on both wheels a little while ago. Then I was able to push him to my new shop in the backyard. A little time to build a bench and bike stand, and we got to here:

Image

A bit later in the winter than I'd planned (today is the first day of Spring) but I'm digging it nonetheless.

I've got some other stuff to deal with:

Image

Image

And I'm likely doing an alternator upgrade and a crank-triggered ignition with that front plate coming off. Possibly a new cam chain if it's showing wear. To get better access to that area, I'll be servicing the fork and head bearings. When the fork goes back together, it will have dual disc sliders, with the full brake upgrade to follow later.

In the meantime I've got to finish some things I'd started at the back end so I can dick with the front end. First, the Progressive shocks (nice pieces!) got entirely too patinated in 10 years on the coast, so they'll get handed down to Edgar, who is all about the patina. I'd come into these a while ago:

Image

They are gas charged and rebound adjustable Sachs shocks from a Moto Guzzi V11 if I've researched it right. Statically, they're 1/2 longer than stock Airhead shocks which matches up nicely with my plans. I'd like Ernst to be a bit more of a backroad scratcher now that I've got Edgar for pillion and getting out of town use. And with the chrome bodies and springs, they really belong here:

Image

I looked inside that book, and I'm just a little disappointed Ernst didn't make the final edit. But with these shocks, perhaps he'll make the next edition.

The bit I didn't know was whether or not the spring rate was anywhere close to what I needed. So I built a test rig:

Image

It gets used like this (you don't see my ass on the end of the board):

Image

I checked the Sachs springs against the OG BMW springs for load at installed length, load at installed less 1.25" (sag height), and load at 1' and 2" less than that. 3" was well beyond the rating of my $10 scale! The Sachs springs are progressive and probably will ride less than the 1/2" taller than stock. Otherwise, they were close enough to stock that it probably won't matter.

With some work with a hole saw, the test rig was also a reassembly rig:

Image

Somewhere in here I ran the shiny bits on the buffer to refresh them:

Image

And then it was time to reinstall. Ernst has an issue with the subframe on the left side:

Image

I had similar issues with some Hagons I wanted to try. So I got the Dremel out and made some clearance to get to here:

Image

That gets us caught up. Updates as they happen. As always, never too quickly.

Mel-
I totally envy your work space.
All this time my mind sort of envisioned you wrenching airheads in the back of a over-patina'd VW Type2 exoskeleton.
Congrats! Very impressive!

I'm digging the work space and I'm working hard to keep it from getting cluttered. It's an amazingly powerful thing to be able to work on something without having to move three things (bikes, VWs, wood butcher stuff) just to start the job.

Serious envy here too, Mel. That's a lovely space.

According to a radio program I heard recently I am a borderline pathological hoarder. My shed is chaotic, but nothing compared to what's in my head.

Well, I'm working on Ernst again and I'm posting so all y'all can be my Accountability Police. This is summarizing the last several months. First, there was some re-blinging required:

Image

Image

Image

Image

Next was processing some dual-disc sliders:

Image

Image

Hey, wait a minute! I'll need a second caliper. Hmmm, what to do? THIS!:

Image

Image

Image

Image

And after re-blinging the one I first blinged 15 years ago in this thread:

Image

But wait a minute! How do you get fluid under pressure to TWO calipers? Well, you send the MC to Apple Hydraulics. I actually sent two, one from Elsa (my RS) to get sleeved to 9/16" and Ernst's original to get a second port drilled and tapped. This is how they looked after the machine work and a round in the dishwasher (did I mention that I'm single?):

Image

Some caliper paint and things are looking good:

Image

Still a bit more to do with the brakes. I have new SS hoses to get from the MC to the fork brace but now have this for making blingtastic hard lines:

Image
Anyway, the fork is back together, the EME alternator and crank-triggered ignition are installed, and I'm pretty much at the fettling stage. More process pix to come!

I've had my son's in-laws visiting the past few days and it's probably just as well that I'm just getting an hour or so to work on the bike between entertaining them. Lotsa evening social time with them, an epic mountain bike ride on Thursday, out to a winery last night for some live music. Good times. The kids are working today and I'll be the one to run her parents back to the airport in a little bit.

New electrics:

Image

Yes, the Reg/Rec says Ducati on it! I'm only a tiny bit concerned for my first move away from Bosch as I understand that Ducati was an electronics company before they made motorbikes.

A key thing when making hardlines is not to put the second flare on the line before the fitting goes on. The key to remembering this is to put the exact fitting in your way on the flare tool:

Image

I will not comment on how I know this.......

The flare tool needs about 3" of straight line to work. So the final bends are done after the flaring, and with the right tool can be done in situ:

Image

Image

Image

Next up is filling the dry system. I like to fill from the bottom, basically starting a reverse bleed:

Image

I did a couple rounds of reverse and conventional bleeding and hydraulic stuff is happening but it's not quite what this raging 750 needs yet. So I did this and will come back to it later:

Image

Also some eccentric adjustment. Because after all, we're all eccentrics in need of some adjustment. I drew on some reference lines:

Image

And after a few tries got this result:

Image

The Thursday ride pointed out some failings on my 1987 Schwinn Cimarron so I attended to them. There's a new cable on the rear brake and new grips to come:

Image

This was the scene a couple days ago. My guest had rented a bike and the rental came with a free shuttle to 7000' (melvilleville is at about 2000'):

Image

I'm usually a purist but I'm definitely not in UP shape right now. I'm almost not in DOWN shape, either. It was an epic ride with views of Mt Shasta and points along the trail where there were alternate lines named things like "Sketchy" and "Vegan Chili." I chose Vegan Chili and am rightly apprehensive about what Sketchy might be! Note that my bike is the only one on the trailer not of this century.

Shiny.. I like a bit of MTB although not many hills around London so tend to ride road or 'gravel' more.
