Re: New ignition system: need advice!

Hi Richard: my first Ducati was a 74 860GT! All sorts of goodies packed inside the headlamp shell. It's good that these bikes are relatively basic; keeps wiring simple.

Re: New ignition system: need advice!

Yes; on an 81 MHR the headlamp shell is empty except for bulbs and wiring. That little can is my blinkie flasher.

Re: So close, 81 MHR

Hi Lumpy: the restoration was an extremely light and brief one as the bike was put away clean all those years ago; I only really started the work at the end of November last year and took my time. Prior to this, I'd bring it out of where ever it was stored and wash it once a year, even if it didn't ...

Re: So close, 81 MHR

Registered, insured and on the road; only 2.5 months late but after 29 years, well worth the wait. Yesterday was my first real ride, about 30km to blow the cobwebs out. I brought it home after about 10km to plug into my SynchPro vac guages and tweak the carbs; settled down to between 1000 and 1100 r...

Re: New ignition system: need advice!

Hey Andy: you need beefier chopsticks! A couple of things I missed mentioning: I had read an earlier Sachse installation write-up that showed the old tab washer being reused for the crank lock nut but this made no sense to me; the old tab washer has an indent on the ID that locks/aligns it with the ...

Re: New ignition system: need advice!

I had promised a proper description of my new electrical set-up and I will do this soon but I wanted to respond to Andy's comments regarding set-up of the Sachse system. As anyone who has looked will know, the Sachse instructions are on-line and suck; all they really need is a light edit and a few m...

Re: Crankcase breather & disconnected air boxes.

Hi Andy: As you may have read already, I installed a Shendingen regulator (FH020AA), a Sachse ignition and better fuse box that uses new-style auto fuses plus a little K&N filter on the end of my original black plastic pipe. My 81 MHR never had the original black plastic breather box; the vent pipe ...

Re: Fitting Dyna Coils to 81 MHR.. Ballast Resistor Needed?

Initially, reused the old Ducati frame and planned to hang the coil block from the old Bosch frame plates but changed my mind and made a hybrid bracket; still uses the cradles from the old Ducati coil frame but mounts roughly in the middle under the tank with one coil feeding forward and the other b...

Re: New ignition system: need advice!

Some closure: the Sachse system was a really easy fix. Testing and timing is really easy (despite what I read in earlier threads) and I ended up attaching the little black box to the rear mudguard adjacent to the new Shendingen regulator. Bike fired up easily on the first kick. I'll do a write-up on...

Re: New ignition system: need advice!

Thanks again. I just removed the old pups they really are in very good condition, even the wiring is still flexible. I tested the pups multiple times and got good, consistent resistance (228 and 232 ohms) even when wobbling with the pup wires; only 25k kms on this bike. I fiddled with a jewelers' sc...

Re: New ignition system: need advice!

Thanks Gardner: As you are aware, the Sachse instructions are not good so every little bit of advice will help. The mounting instructions are probably the worst I've ever seen for anything I've ever bought: 3 Mounting • Remove all Bosch components, the trigger wheel on the crankshaft, too. • Mount t...

Re: 81 MHR Ducati regulator question for experts!

Got an answer; the older regulators require a switched 12v for a reference voltage. My new Shendingen one does not.

81 MHR Ducati regulator question for experts!

What is the role of the Brown connection? The two yellows feed from the alternator, the battery -ve connects to the body of the regulator via one of the frame bolts and the red connects to the 25A fuse as does the +ve battery terminal. The two 8A fuses and the brown wire are fed from the ignition sw...

New ignition system: need advice!

I am waiting for my new Sachse ignition to arrive for my 81 MHR; the new Dyna coils and HT leads are here as is the new Shendingen regulator. I had read a number of positive references of Shendingen regulators being used on older bevel 900s and figured that my old Ducati Electronica regulator may no...
