Hello! I'm Cristian from Spain, and i have a Mito 125 2006, and i have some questions.

I've been looking your forum but i don't understand italian and google traductor is not very good.

My mito have:

200h and wossner 2 ring (0.85 squish) 7mm band
phbh28bd 65-70-120
original exhaust derestricted
ducati energia ignition

I want to know about the restriction of cdi ducati, and i have plans to buy artigianale sp from Mat, but i don't want if i buy it, put on the bike and don't go more than 11000rpm like the original exhaust.

I plan to do:

200h and wossner 2ring (0.85 squish) 7mm band
phbh 28 bd with x4 and bn274 with 120/125
filtro cornuto
artigianale sp 95

Thank you, and congratulations to the forum, is incredible!

Ducati Energia's ignition has no limitation on Mito Ev edition.
I suggest you to check your compression ratio.
200h, with 0.80 squish, makes your engine reach 15:1 compression ratio: it was a good value with older italian gasoline that had lead inside.
Today (in Italy) gasoline is without lead, and it's very dangerous a compression ratio near 15:1.

I don't know how spanish gasoline is...

i was reading ev model euro 2 with ducati ignition have an advance ignition curve at high rpm that kills top end rpm. what do you know about this?

i have 160 psi on the clock measuring the head compression, and i don't feel any strange thing. in spain there are 95 and 98, i use 98

Only problem i can was using a spark plug with too much km and around 8-10k rpm makes little cut to ignition constantly, when i put another plug, same model but used too i have the same problem but much less, is rare because it only does when the bike is more than 10 minutes running, but i think is the spark plug, monday i will buy one new and try.

Thanks!

Yes, at high revs the Ducati Energia euro2 kills top end rpm.
The cause is the high ignition timing advance, look at the graph:

Ops, I was sure that only SP525 has this cut problem! Sorry for my mistake.

okay, and talking about rpm with artigianale what is the highest rpm i can see on the clock with standard ducati cdi?

i was thinking about detonation, what are the symptoms? do you believe that pulls in high rpm when the bike is hot may be due to the detonation?


Thanks again!

I never use the Ducati Energia ignition. The Ducati Energia CDI is good for 15hp engines. I use Zeeltronic programmable ignition, so I use the right ignition advance curves.


I advise you phbh 28 bd with x4 and bn272 with 125.

[cervatillo1985]

thank you, i will buy zeeltronic and forget ducati energia cdi. with the zeel i can set te pv aperture and closing? can you post a good ignition map for the zeeltronic with artigianale and 28bd with 200h?

I ordered 125 and bn274, is a problem run 274 instead of 272? x4 is the standard needle?

thank you, again you saved my life!

There's a dedicated topic in the advanced area http://forum.mitoclu...ili-zeeltronic/

If I'm not mistaken the bn270 is fitted as standard, the bn274 is too large.

With the zeeltronic you can set the PV aperture and closing. You can use the standard Zeel ignition map.

[cervatillo1985]

okay, thanks, i changed the order buying bn272 instead bn274.

hello again, with 200h with 7mm squish band, what squish do you recommend using 98 octane? now i'm using 0.85, thanks!

[cervatillo1985]

hello, can anybody help me? i don't want to broken the engine

Thanks again and sorry for my insistence

with this head is preferably 0.95-1,00mm, otherwise the compression ratio is too high.
