A beautiful machine that I'm sure has sparked a few conversations in your living room.

The regular comment it got was... 'Your not married are you... '   ;D

The local bike shop had trouble removing the old rear tyre, as it was so hard and dried out. They had to put a tyre warmer on it for awhile before they could safely lever it off. I'd told them to be extra careful, as the wheels are known to be easily damaged. Going to polish all the alloy adjusters etc before fitting the rear wheel, then repeat the process with the front. Its been so long, that I cant remember if the bike is stable on its centre stand with the front wheel removed..

A race mate of ours had an MHR and he rarely rode it.  It had become too precious, so he sold it.  That think looked and sounded wonderful.

Lovely bike you are are starting with.

Slow progress, but got the new Avon tyres on the wheels, and made a start on removing the bodywork to get at the engine..

With the bodywork removed, I can do some work on the engine, which looks pretty clean in the photo below, but in reality its covered in dust and the alloy that was hidden behind the fairing is dull and needs a good polish.

It'll be getting an oil change and with the fairing lowers removed I can access the coils, one of which I know has a problem, which I botched 25 years ago, so I can finally make amends.

The chromed cup between the cylinders (which should be black, but I chromed mine) is the cover for the oil filter. On the early Bevel drive twins this was the location for the points ignition. When Ducati went over to electronic ignition, they reused this area for the oil filter.

I've owned a many different bikes over the years, and this one, with its 900SS Desmo engine is my all time favourite. Its not that powerful these days, but its fast enough and it sounds glorious. Not just the exhaust note through the Conti 'silencers', but also there's a high pitched ringing that gets louder as the revs soar.. that's the sound of the bevel gears in the heads meshing at high speed. Then of course if you happen to roll off the throttle at night, you'll see a blue flame belching out of the bell mouths across your knee.

I'm looking forward to hearing it run again, I just hope there are no unexpected gremlins inside the engine after its long sleep.

When I first restored the bike all those years ago, as I installed the wiring loom etc, I noticed that one of the low tension wires had broken as it goes into the plastic boy of the coil. There wasn't enough wire left to solder it back together, so I glued it back together with epoxy, knowing it was a bodge.

Now it was finally time to fix the problem correctly. Having removed the coil pack, I decided the damaged coil should be replaced. Though a new coil wasn't available, the same coil was also fitted to some Suzukis GT25/380 etc. So given time I should be able to pic a used one up on Ebay.

But then the bike would be running with 40 year old coils, not ideal for a good spark. So instead I went out and bought a pair of new Dyna 5.0 Ohm coils which were supposed to be direct replacements. But they aren't as the mounts are slightly different. I'll have to make a new coil mount instead when I have time.
