That is my plan Steffen - I will make some bracing to go from the flywheel to the bracket.

Decided to have a go at seeing where I could mount the Power Dynamo Relay, Controller and Regulator.

This bike has been previously fitted with a separate ignition switch above the battery box which I will be retaining and even though you don't need to run a battery with the Power Dynamo, I have decided to fit a battery and I will wire the bike so that the headlights are always "on" which is required by Australian law on later bikes. 

A Lithium battery is the ideal choice as they don't self discharge, are lightweight and relatively small......however Lithium batteries don't like to be continuously discharged or overcharged and sometimes require a "Wake Up" discharge if they haven't been used for a while. I have ordered a small Lithium battery with inbuilt battery management to regulate the charging and the small size means that I can fit the battery and Power Dynamo parts inside the battery cover. If the battery needs to be "Woken Up" after a long period of inactivity, the headlight current draw when the bike is turned on will be sufficient to wake up the battery.

The first photo shows the battery I will be using, the second photo shows everything in position with a dummy battery and the third photo shows the battery cover fitted with the Power Dynamo parts inside inside.

Nice!
Did you realy need the Relaise??


Dont you have „Klemme 2“  (in english clamp?) on your Ignition Lock?

Gidday Anulu
Thank you for your reply and yes, you don't need the relay if you have a standard ignition/headlight switch which will earth the blue/white wire when switched off.

Unfortunately my bike doesn't have the original BMW ignition/headlight switch which has been replaced with a "Dummy" switch on the headlight for authenticity appearances. I looked at buying an original switch but after finding out the cost I decided it wasn't worth the money and will stick with the key operated switch that has been fitted on the frame above the battery box.

This means that the wiring of this bike will be nothing like the original and I will be using relays for the headlights, horn and immobiliser to minimise current draw through the handlebar switches.

This arrangement won't meet with everyone's approval however it will look original apart from the key operated switch which is the main thing.

Below are a couple of photos showing the key operated switch.

Ah ok.

Ther is another Buck ( before you have to go to troubleshooting for a long time)
All 4 switches (from the ignitioncontrollbox) must be OFF!! ( for BMW )
The factory are delivered is “ON“ ( for any twotakt-Motor

Thanks for the heads up about the dip switches Anulu.

I have been busy doing welding jobs for family and friends who always want welding done after you have cleaned up and put everything away.....argh!

The cylinder head now has new valve guides, new valves, new valve springs and retaining washers - I had to use the old valve guide retaining clips because the clips supplied with the new valve guides were too small. The cylinder has been bored and honed to suit the new piston and has also received a lick of black paint.

I have also fitted new bearings to the camshaft and am getting ready to start to put the motor back together.

Hi Brian,

looks very good. Did you ream the valve guides properly after installation? The clips would be less of a concern. Should work with the old ones.

Tom - Yes the valve guides and valves have been correctly fitted, in fact the old valve guides showed signs of blow by between the head and outside of the guides.

Went to put the engine together today and ran into a missing part problem but firstly, I decided to pull the oil pump apart to check the gears and body clearances which were all very good as it turned out. What I did notice is that the oil pump had the wrong bolts/screws in the wrong holes which have now been fixed.

My missing part problem is that I can't find the spacer ring that goes between the crankshaft bearing and the oil slinger - this is a spacer with an internal taper and I am happy to make one as it would be quicker than buying one. So if any of you guys have the dimensions for this spacer ring it would be appreciated if you could let me know what the dimensions are. The part number is 17 on the Ulis diagram and part number 5 on the Salis diagram - BMW part #0016114, see attached photo.

Photo 1 is Salis Spacer Ring listing, Photo 2 is the oil pump before disassembly and photo 3 clearly shows where the countersunk screw fits

While I am waiting for the crankshaft spacer ring I decided to put the headlight on and on checking the Generator and Neutral globes noticed that their globe holders are corroded.....another thing to fix which is not surprising. Also noticed that the yellow wire coming from the headlight switch has melted at some stage which will be another job to fix when I repaint the handlebar switch blocks.

Funny how there are always other little jobs to sort out

I looked at the speedometer and noticed that paint was flaking off the internal plastic rim which wasn't ideal. I removed the chrome ring and speedo glass and scraped off the flaking paint, reset the odometer to zero and put the speedo back together. I didn't repaint where the paint was flaking from as it is cosmetic and the Australian UV would make short work of any new paint.

Also noticed that the the brake rod hole on the foot brake lever was also worn so I knocked up a small 8mm bronze bush to centralise the pin.

Have been doing stuff that takes forever and you have no output to show for it.....the joys of restoration.

Am still waiting for the spacer ring to put the motor back together and in the meantime have been trying a few different wiring options/configurations inside the headlight where wires are usually pushed together and shoved inside the headlight so that no one can see the mess....

Pulled the Headlight/Park light switch apart to find the cause of the melted yellow wire.... one of the switch sliders has been dislodged and was protruding from the switch body; the yellow wire had disconnected from the switch terminal because of a dry solder joint; the black wire has a dry joint and the blue/white wire has also partially melted with a bad solder joint and burnt switch contact.

This bike is still testing me!

My plan is to refurbish the switch block (and the other switch block as well) by repainting, replacing the wires and PVC sheath, correctly relocating the switch slider back inside the switch and using the unused switch contacts by turning the switch contact board upside down. This will be detailed in later posts after I have repainted the switch block housings.

The photos below show the condition of the switch/wiring and the mounting of the indicator can and high/low beam relays inside the headlight housing

Fixed the faulty headlight switch today by repairing the nylon slider block to stop the contact sliding out, using the unused switch contacts and fitting new wires.

This will be refitted once I have repainted the hand control body

Perhaps the very best modification you can do to the headlight shell, is to paint the inside white!!

Then you can see exactly what you are doing and where all the wires are going.

I know this is has been a modification since at least the 1960s.  Or if you don't want to paint, fold a piece of white paper or card inside.
