Laverda 750 SFC 1974 replica

isn't this to be a 270 degree engine ?
if that is the case then the only ignition that will work is the Ignitech

 
No after talk with Angelo and after i saw his bike with same specs like will be mine i decided to keep stock crankshaft only lighten it.

A bit tricky doing points if it had been planned as a 270.
For a 270 any 2 channel electronic ign should do the job, with the triggers mounted 45deg from 180, but Ignitech are just so simple. They recommend hall effect due to the size and half crank speed for 750s. I have used a modified version of their system for Guzzi.
Hey Phil, that looks like you have really simplified it from the points :-)
 
yes Tippie - it's just a std Boyer/Bransden with a Pk moved 45? from it's original position and I've separated the 2 Pk's as they are normally joined together by a circuit behind them. Run like that for about 20 years. - regards - Phil
 
Damn i really don't know what to do now :( electronic ignition or points?  Another problem is that i wanted to use dual output coil http://www.elektronik-sachse.de/shopsystem/product_info.php?info=p28_dyna-ignition-coil-2.html. What coils do you guys use with points?? i don't have enough place for original coils

Or can i use this coil with points too? probably not ?

The Dyna coil will work fine but as you see yourself it can?t do the job for both cylinders if you use points. You need an electronic system with one pickup triggered twice per rotation, once for each cylinder, and then you can use the twin pole coil. Don?t get confused by the good natured banter re points vs electronic. Points are dead simple and do the job fine but need to be kept track of as they do wear, can get dirty etc. Electronic is (should be) set and forget, but if they do stuff up it can be a challenge to find the fault.

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

ok so i need 2x3ohm single pole coils  but i can't find them anywhere i find dual pole coil with 3 ohm without problem. But i can't find 3ohm single pole coils. I can only find coils with much lower  ohm values
 
Nology Pro Fire, small but big in volts, best bang for 0.0mm per grunt

you can run 2 x 152 051 300 single outlet coils or 1 x 152 051 350 dual coil
is up to you, flip a coin
I prefer to run a single coil per cylinder
