Sachse-Electrtonics Ignition

[flathead]

Anybody ever use one of these?

It looks pretty cool, retains the stock coils and charging system. Plus it mounts on the crank over the rotor and there are 9 selectable timing curves built into the control. 299 euro is a little steep for a stock rider but really wouldn't be out of reason for a performance engine.

Just curious if anyone else had used one of these and could sound off on reliability and enhanced performance. I've collected the stuff to build a crank mounted analog CDI ignition for my cl72 flattracker and before I proceed further I'd like to get a little feedback as to this option.

Thanks,
Mark

Mark, looks like a nice and easy plug and play deal. Does it reatin the rotor for the charging system?

Hi,

I do not have this ignition, but a self made ignition,
the reason I react on this post is that it works from the crank, and there 's really not a better place for the timing than that. That was the only reason for me to build one myself, and it rums SO MUCH better.

Davomoto,

Looks like from the photo's that it does retain the rotor. Can't say for sure.

Jensen,

Care to share any info on your end of crank settup?
CDI or a hybrid with some type of electronic advance?

I'm building mine from the cheap chinese CRF 50 clone inner rotor kits you see all the time on Ebay.

Documentation that comes with these things leaves a whole lot to the imagination. No timing marks, red wire to black wire, etc. So we did some testing just to establish the timing and found that the advance curve was around 20 degrees at 1k-1.5K with a pretty flat curve thru 7.5k. Can't say past that as my test setup will not spin higher than 7500, but I expect to see a few degrees in retard somewhere around 9k. Timing curve does appears to be consistant from one module to the next.

Good thing about these chinese CDI sytems is the cost. The whole setup is around 40 bucks (takes 2 for a 180 crank or 1 for a 360 crank) , coils are less than 20 bucks , and a spare control module is 10-20 bucks.

For what its worth, I paid a little over $400 for the PVL that I used on my old 400 Yamaha single drag bike and after 4 runs I've got no spark.

Mark,

I have one of those cheap Chinese units for a CB160 but how do you plan on getting two sparks per revolution, or is it on a Dream?

I have used dyna S on a CB72 (no charging circuit) crank mounted and that works well and I also adapted a GSX250 Suzuki CDI to fit on another CB72 again no charging

Hi,

I use CDI as ignition, one per cylinder, placed the pick ups in the crankcase side cover (generator cover), and the advance is controlled by software (I can program the curve).

The whole system is invisible from the outside and works (after 2 years of refinements) good.

davo,
are you mounting that crf50 rotor at the crank or at the points cam?
