Hello all. Just picked up an 87 Paso. Last time I had a Duc was almost 10 years ago. Wasn't really looking for one but I came across a non runner for little $ . Couple "odd "things about the motor. It has the 40 mm Del Orto's on it and Carbon cans but it is a wet clutch motor with twin plug heads. Does anyone know what I have? I thought it might be a newer M750 but it has the older cam covers and what appears to be 20 years of grime. Belts look fine, but they will be changed. Cases are black as well as the cylinder heads but the rest of the motor is unpainted. Any help would greatly be appreciated. Thank you.

Welcome on board.
Dell'Ortos carbs were fitted quite often on Pasos instead of stock Weber.
Put some pics, so we can tell you more about.
Ciao

A much modded paso,as are most of them these days

Welcome!

Pics would be good.

Where are you located?

Welcome Ike! A Paso with mods, mmmm...there's something you don't see every day!

People have tried to shoehorn all sorts of engines in the Paso frame (Desmo_Demon, what happened to the MegaPaso?).

Enjoy the forum.

You might have a custom tuning on an Elephant or Indiana engine.
Dual spark modding is not so hard to build, while wet clutch on pantah engine was not used on Pasos.
A complete maintenace (valve clearance, belts, spark plugs, filters and, of course oil) should give you a very performing Paso

I spoke to a reliable source and was told all 750 Pasos that came to Canada were a wet clutch motor. The speedo is also in kmh . The twin plug is definately a mod but same source said it was a period conversion. No odd spacers at mounting locations ,etc . Looks completely factory. can anyone else support this? I'll get some pics up soon.

That info is incorrect.
I wonder how your timing setup is as not changing it with a dual spark plug conversion can cause engine damage.

Can't tell you about the timing but when I line up all my timing marks,everything is as it should be. My source with regards to the motor come straight from Ducati North America. If anyone else on this forum from Canada can shed some light on this it would be greatly appreciated. Thank you.

I quess, that original engine have blown and this Your engine have been rebuild from 2 different engines. Its easy to put older model cam covers to it. And this is FIRST time, as someone say, that Paso 750 have wet clutch. I never belive that such engine is coming from factory. If factory had made many such to markets, here should surely someone known about such "wet clutch 750 Paso negine". Its possible to put 750cc wet clutch Supersport(90's) engine to Paso frame with some spacers. Anyway Paso 750 engine have better cams compared to 750 Supersport engine, so its not so bad idea to adopt parts from 2 different engines and make one good...

That 2 spark system is easier to make to air/oil cooled 750cc(or 900SS) compared to water cooleed engines (906,907IE,ST, etc), as heads are different and water cooleed heads have those water lines .... It would be nice to see fotos/pictures from that 2 spark system electrics, to see how nice they have be done. If its factory made, then all wires are "integrated" to harneses well. In microfilm there is no other wirings and anything from such 2 spark system. There is only "Kokusan and Marelli versions".

We`re all eager to learn but I doubt it. There`s no such thing documented.

Regarding the dual plugs. Advanced ignition needs to be reduced. Dual sparks cause a stronger and faster ignition meaning it moves closer to TDC creating more stress on pistons and conrods. For this you`d need different CDI units.

Anyway Paso 750 engine have better cams compared to 750 Supersport engine

Do they ? The pistons have a higher compression than the ones of the SS.

Sorry, i did small mistake, 1994-1996 750 Monster have same cams, as 750 Paso. I mixed little those 900 cams, my mistake. 1999-> 750 Supersport(injected) have different cams.

I'll take some pics tonite and get them up. Dual plug setup doesn't look like anything too fancy. Looks like a stock wiring harnes but the coils have two leads instead of one. Two coils with two leads on each. Plugs are under the cam covers. Thanks for the input on the motor. Looking forward to getting it running. Speaking of CDI,s that is why it's not running. Ive only got spark to front cylinder . When I switch CDI's it changes so it sparks only on rear cylinder. New CDI on order as well as cam belts, etc.

Sounds like you have Kokusan boxes.
If you could stop the box order, I`d try this:

Better ignition f less money AND,
programmable to fit your dual plugged heads.

Where are you located? CA Cycleworks sells them in US.

No Paso's were wet clutch from the factory. Why do you think it has a wet clutch? Can you give us all a picture? I know for sure that No one at DNA knows anything about a Paso. Someone may own one (which I doubt) but their knowledge is less than zero.

The Indiana was a dry clutch as well. I have one. I don't have an elefant but know someone who does and I'm 99% sure that is also a dry clutch. I will ask.

Send us some pics!
