Boxer Bolshie's '84 Restoration and Rant

[ira_ryan_cycles]

wow, i just scrolled up and checked out the bike. very nice work. those tires look like a cozy fit but very well rounded dry mock up.

thanks for posting.

Haven't posted much about my progress but feel I've done enough now for an update.  

Note: tank is just on for show as I'm still not done painting it.

A few pics of my finally "done" DIY fibreglass seat pan.  A bit heavier than the OEM pan but I did it myself and I love learning shiit!





I did the bottom with under coating for some sound and vibration deadener



The large holes are like the OEM for the air and moisture to escape while the smaller holes are for the hinges (embedded inside are aluminum brackets to reinforce the hinges).

Got a bit done today, pics soon.

FINISHED TODAY:
-Got most of the wires strapped into place
-Cables fitted
-Seat pan attached with old hinges.  Just have to bolt on the lock catch and upholster it. Turned out a little short but I'll add something between the front of the pan and the tank.  I've been thinking I might rather have a single and a half seat with a rack extension
-Fixed the exhaust wrap that wasn't secure enough
-Attached DIY battery covers
-Fabricated and attached DIY dash
-Replaced final drive fluid
-Finally received my back ordered oil eye for the gearbox and installed it.
-Bolted and connected starter
-Re-routed crank case breather
-Installed starter cover, airbox filter and cover, and alternator cover
-And a half dozen other little things

WHAT'S LEFT:
-Finish wiring for speedo
-Figure out where I want to install the ignition switch
-Fill forks with fluid
-Fill brakes with fluid
-Install Motorrad Electric Alpha ignition trigger, control, and coil when they arrive.
-Triple check all torque points
-Upholster seat
-Paint and install rear rack
-Double and triple check everything
-Fill fuel tank, pray to gawds, and start 'er up!  
-Fix one of the pannier locks
-Finish first helmet
-There's always something I'll remember later

Anyone know what these two wires connect to?

A:?
B:?

NOTE that "B" has a hermaphrodite (female/male spade) connector

[Boxer_Bolshie]

I realized that the previous pic makes it look like the wires are connected to each other but they're not so here's another pic

Sorry for the blurriness

[Boxer_Bolshie]

I am wiring the speedo and have some wires unaccounted for.  Anyone want to give it a shot and tell me to what these wires connect to?  And should I connect all of the BMW brown ground wires to the one black Acewell wire?

NOTE: The blue Acewell wire noted as fuel gauge will not be used



Here is what is supposed to be my wire diagram (my actual wiring seems a little different)



Here is the Acewell speedo diagram I got from Avdrider.com (someone else's interpretation) NOTE: The star is noted as the gen light hookup however without some fancy knowhow, I probably won't be using this



Here is another colour code for the Acewell harness to BMW harness

[Boxer_Bolshie]

So this is what I've figured out so far on the extra wires.

The BMW blue and one of the browns go to the generator charge light
The two BMW black and white striped wires go to something called a scale light (maybe dimmer light/switch?)
The BMW blue and green striped wire with one of the brown wires go to something called a speed warning light.

I am headed to NAPA to pickup a light for the gen charge but the last two I have no idea what to do with.  Anyone want to fill me in?

There is a bracket welded to the frame backbone near the regulator that captures about 5 -I think- brown ground wires; all in one tidy ring connector. I see one of your brown ground wires spliced into another colored wire leading off somewhere. Does this go to a ground terminal or should the OEM brown and the colored wire meet at the chassis ground point?

[Boxer_Bolshie]

Thanks Monty!

I connected the group of grounds (like yours) on the rear bracket



The grounds in my previous post each go to a warning light on the dash (or tacho).  I now realize that I will still need to install two warning lights, the gen light and what I think is called the speed warning light (maybe this is the shift light?).  Those two warning lights each need a ground and so that whittled my group down to two.  One for sure will connect to the Acewell ground, however, I am unsure where the last one will connect to.  There are the two black and white striped wires which my manual says goes to the "scale light" which I first need to figure out what the heck that is and then whether or not it needs a ground or whatnot.

[Boxer_Bolshie]

So the "white" and black striped wires are actually grey and black striped wires and the "scale light" is the speedo light.  It also goes on into the headlight which is why there are two wires.  I can just connect these two together as I won't need the old speedo light as the new one already has power for it's lights.  Meanwhile the two leftover ground wires can connect together to the black Acewell ground wire and we can call that all good!

[montmil]

That light blue OEM BMW wire can be traced on the wiring diagram you posted.

It runs from the diode board to the voltage regulator to the GEN bulb.

[Boxer_Bolshie]

Thanks again.

I've got just about everything connected and just have to pick up a couple of dash lights (one for the gen and the other for the shift warning maybe?) and then I am set (knock on wood)

[Boxer_Bolshie]

Okay so I am done fiddle farting around with the seat/pan and will finish it up sometime in the future.  Meanwhile I just got this EZ Burg off of eBay for $75 plus ship and though it was advertized for 1986 to 1995 it fit perfectly sans the cowling and glove box!  Will need to get a fitting cowling and make something to work as a glove box but am not too worried and it's comfy!  Just one little tear to fix

[Boxer_Bolshie]

Brake and fork fluids DONE!  

A little easier than my procrastination warranted!

Will be going through all the torque specs to make sure the wheels don't fall off and the lash gaps to make sure she's ready for the final parts when they arrive!!!!

Feeling pretty good about the last few days of work on Bolshie!
