What would be to optimum advance curve for a 450?
Something that starts at 0 deg and ends at 28 deg around 4000 rpm or a little more?
Would the curve be a straight line?

The reason I'm asking is the Ducati Electronica ignition on my 450D is finally getting sad, which is very good considering its age.
It's not a track bike but was once and has slightly higher compression and larger valves and carb.

Hi Graeme,

Have you considered the Microclassic system that Ian Glover (in Melbourne) makes? The web site is microclassicignitions.com
I quote from it:

"Programmable digital ignition system for Ducati Singles

The MicroClassic Single ignition system is designed for Ducati Singles. It includes everything listed below. The trigger is a drop in replacement for the existing points system."

Ian races a very fast narrow case 450. Yes it's a 450; he cast his own crankcases.

I'll try and get some photos of this machine in October when the Southern Classic race meeting happens.

Cheers,

Stewart D

Thanks Stewart, I've sent some questions to MicroClassicIgnitions.
$660 is a lot of money for a road bike, but i guess I get what I pay for.

Eldert, I hadn't forgotten you suggested this ignition once before when I fitted a Sachse to my RT, but again the cost was a factor.

Thanks
Graeme
