Re: Smoking under acceleration.

Well.... ain't it an arse when reality disproves a theory. With the old oil pump fitted it's still smoking and just revving him up on the stand it actually seemed worse!! I quickly whipped off the rear carb and again there was plenty of oil in the manifold and also a drip was seen on the outside of ...

Re: bosch ignition pickup tool Q

I went the Sacshe route; a little expensive but very easy to install and set-up
Yep, same here & I agree completely. Real easy to set up, allows real easy starting and a lovely smooth ignition curve with no sudden jumps in advance. Choice of curves too.

Re: Smoking under acceleration.

Again thanks for all the replies guys - it helps clear ones thoughts when brain storming... Did a previous owner use some RS bearings on the camshaft-bevel side ? that could prevent/decrease oil flowing to the bevels and raising the level in the head. You say the guide on the inlet are (original) O-...

Re: Smoking under acceleration.

Thanks Craig. Your advice is always welcome and appreciated. Blue smoke under acceleration is normally rings, sad to say, Andy ... I agree but what I don't understand is why there is oil in the rear cylinder's inlet manifold? But first check the engine breather is working. (I admit I don't understan...

Smoking under acceleration.

I'd be grateful for any input people would have on a smoking issue I have with a Darmah after a top end rebuild. The motor fired up fine on it's first attempt with no or a little smoking but after a gentle 5 mile shake down run oil was seen seeping from the rear exhaust collar. Further investigation...

Re: desmo exhaust valve seals

From here*, I see that the dimensions (ID followed by x-section) for OR 2031 are 7.65 x 1.78. But I cannot find OR 107 referenced either by this source, or anywhere else. So maybe OR 107 is no longer produced ...? * http://www.argotmf.com/pdf/oring/OR_NWLIS.pdf Well I've just found a reference that...

And here's the front exhaust - massive contrast with the camera light but it does better show the shadow in the lee side of the guide where the oil residue hasn't settled. You can also see the deposit on the guide.

Re: desmo exhaust valve seals

exhuast_leak.jpg Does this look like a guide leak? From either the stem or guide/head? You can just about see some oil on the end of the guide. I am also seeing oil around the spark plug thread and when peering through I can see quite a heavy(ish) film of oil on the bore. So am I on the wrong track...

Re: desmo exhaust valve seals

Much of the issue here is the multitude of different guides, some after market, and seals which often share the same part numbers. I have two different types of guides/seals in the heads with the exhausts having just the top hat and the inlets just the o rings. The exhaust closing rockers had been g...

Re: desmo exhaust valve seals

Because in 1980, Ducati DID change the valve guide O-ring. The new O-ring got part number 0799.92.395, a change from the previous part number of 0400.17.030 to (ref Tavola 6, 900SD Sport Desmo Darmah Edizione 1980 ). Unfortunately, the 1980 parts book doesn't give the size of this new seal, so it's...

Not trying to steal Andy Capp's thunder but I'm planning on chucking the voltmeter and fitting the standard charge warning light from here https://www.improvingclassicmotorcycles.com/products.htm It doesn't just come on but flashes at different rates depending on the condition to be indicated, low/h...

Wow! a great fast reply and hopefully useful for others. Top man! :-D -*!^- I did spend some time trying to find the same but always ended up on sites that required signing up to view the wiring diagram, but that's just what I need - and, amazingly, my best guess was correct. I won't be using the L ...

Re: Looking for a technique

I waxed the guard
I've been toying with the idea of putting a washer
I've just had my frame wet painted and the advised method to prevent scratching/sticking was to use red rubber grease, as used for brake caliper maintenance, or nylon washers.

Another dreaded regulator/rectifier question

I've purchased a new Ducati Energia 25a reg/rec that fits both the Pantah & the Darmah which has the orange connector and 5 terminals, G, G, +B, L & C. I've already figured out the two Gs are for the alternator & the +B is for the (positive) battery but I'm unsure what the L & C are for. My best gue...

Re: Fork oil grade 1980 SD 38mm Marzocchis

"DO NOT GO BY LABELLED OIL WEIGHT! Not only is this a poor way to decide which oil to use, but each manufacturer seems to be on a different scale. For example Maxima RSF 7wt is actually lighter than Spectro 5wt and Silkolene Pro RSF 7.5wt is actually heavier than Showa SS-8 10wt. This is not a judgm...
