all depends on what coils and ignition system you are going to run

work out what ignition system you will be installing
then decide on what coils you wish to use

example, if installing a Sachse system, you can install 2 x 3 ohm single pole coils or 1 x dual pole coil
can use any 3 ohm coil, I like the Nology coils due to their small size, can fit them anywhere

there is no need to run at Bosch 40 coils with an electronic ignition though you can if you wish but changing to something far smaller frees up so much more room in the frame

Can you attach some link to dual pole coil? i can find only single pole coils on internet shops
 
you cannot run a dual coil if you are going to twist the crank to 270 degrees
will only run with 2 x singles

use Nology coils for their small size, or PVL, are the exact same coil, different name
 
Great thanks i will need light soon :D

Another question i rebuild 38mm ceriani fortks today only thing left is oil. What oil do you guys use? (my style fast road and some track riding)

I found lot of different data on internet.

Most common is 380cc  air gap 110-120mm and what oil viscosity ? i found data on internet from 5 to 20w ?

I was thinking to put 20w is it ok because i don't wont to have forks unresponsive
 
No idea,I uses fork compressed spring out and 130mm from the top of the fork.Emulators are a good thing,BTW then out as well for the oil level
 
I was reading laverdamania and they say that this is mistake in manual
http://www.laverdamania.net/suspensiongb.htm

:D

So 200ml :D is the correct value

Damn i hate internet more you read more info you get less you know :D
 
So i need some help again.

It is time to choose ignition sistem but i don't know witch is the best on the market (quality/price ) i was looking for some data but cant find much.

Are all of those ignitions programmable ?

I'm lost here so what do you guys recommend?

Paul Marx recommends the latest Bosch system - it's called P-O-I-N-T-S  :D :D

It's all very well recommending the latest cutting edge technology, but you forgot to mention the specialized hardware you need to program it.
It gets confusing when they come in imperial or metric sizes :D

I'm not going to use stock engine. I will use 900ccm pistons lighten crank 5c cam,.. work on cilinder, barrels, crank will be done by moto officina. They made couple of engines with same specs like mine and they say that contact point aren't fast enough for engine tuned so far.

WTF?  50 cc 2-cylinder Hondas revved to 22000rpm with points!  What are you trying to achieve, 30000rpm?  Won't manage that, no matter which ignition you use.

MV triples went to 13000 and more rpm with points as well.

Well i don't have experiences on engine tuning, They said that i can use contact points but that i can achieve much nicer revving with electric ignition. One more thing is that i don't have stock ignition,.. and at the and price is same or cheaper if i buy electronic ignition.
 
An electronic ignition can be more precise and reliable, and will be maintenance free too.  But points can work rather well to quite surprising revs.
