Just linked from "forum desmodromico" : how to machine stock heads to place a second spark plug!
Just get drunk watching pics!!!

With dual spark conversions you really have to know what you`re doing. If the timing is not set exact you can ruin your engine pretty fast.

Re: upgrading desmodue to dual spark!
They have modified many 900cc Supersport(91-97) syl. heads for 2 spark plugs, but that is easier in that air/oil cooleed engine... Some of them used Harley coils.

Re: upgrading desmodue to dual spark!
here's the link! It didn't worked yesterday
The write about 350, 650 750 and 900 heads machined to place a second plug!
I have not enough time to read the entire topic
So busy by now!

Re: upgrading desmodue to dual spark!
Very interesting.
On a 900 engine, he has reached 92hp, from 78hp of the stock engine.
If someone needs the translation...

Re: upgrading desmodue to dual spark!
So he has raised the compression to 13:1 with a new set of pistons,ported the head with new valves,added Benzene to the fuel as well as the additional spark

Re: upgrading desmodue to dual spark!
More compression=more power, simple. But lifetime of engine will be much lower. Its wiser to make more CC*s, than only compression...
But Ducapaso is very good in marketing, as he put some pipe there(upside down, like newer Ducati forks... ) with stamped "made in Italy"... Are you working with marketing ???

Re: upgrading desmodue to dual spark!
I wonder what power increase you could have by a mild compression boost, say 10:1 and the port and polish with the extra spark. Adding the second plug seems to be fairly easy and I do have a spare set of heads and cylinders,hmmmmm another project to put on the todo list, if I ever get through the honeydo list

Re: upgrading desmodue to dual spark!
Dual spark is not bad idea at all, as also factory have gone that way.... Its good for fuel burning surely. Its much easier to do to air/oil cooleed engines, than to water cooleed ones. If do such to water engine, then have to be VERY sure about water/oil lines in sylinder head. Surely that can be done also, but i wouldnt do it to my OWN "water heads". As i told earlier, many guys have done it to air /oil cooleed 900cc SS engines with quite good results, but its not only way to get more power.... There is also big bore kits, etc... ALL depends, HOW MUCH MONEY u are ready to invest such old bike, as Pasos are... I think that allways... With enough money u can also take flight to space...

Re: upgrading desmodue to dual spark!
What is the power difference between 2V 1000 & 1000DS?
I think dual spark is mainly for emissions, not power,
but what do I know....

Re: upgrading desmodue to dual spark!
dual spark is strictly a flame propagation thing, related to higher octane fuels required for higher compression ratios.don't think anyone wants to go there ...again
that is why he adds green benzene in the 13:1 version of his mod
I don't actually think dual spark would add anything to a normal compression engine but it would sure be cool
