Original Speedo with Motoscope Pro - How?

[ccalverto]

Has anyone had success in using the original speedo on a 1991 K100RS 16v with the Motogadget Motoscope Pro - if so How?

Why do you want two speedos?

[ccalverto]

Hahaha Valid Question - i mean the original Speedo sensor in the rear wheel and the motoscope pro reading it to display the correct speed....


i don't really want to install another speedo sensor; i'd rather use the original

[Boxermann]

I tried this but couldn't make it work. The OEM signal is too weak. I've also tried a BEP, but the signal it put out to the Motoscope was way to uneven.


I ended up using the magneto sensor that came with the Motoscope and it works fine. I hid the sensor under the rear wheel caliper and glued the magneto to the rotor.

Could i trouble you for some pictures on how you mounted it and glued it etc? if its not too much trouble?

[Boxermann]

No prob. I can try to take some pictures later today.

The OEM speed sensor is a variable reluctance transducer that is incompatible with modern digital gauges. The output from the sensor needs to be conditioned to work properly, that is converted to a square wave of 12V amplitude. I build  a TGPI gear indicator circuit with such a conditioner included.  In addition I have an additional circuit to condition the engine RPM signal for a clean tach reading.  I can build the board with just the conditioning circuitry for CA$21.00.  http://www.motobrick.com/index.php/topic,3421.0.html

Would love to purchase one that does all three.... please and thank you.

Yes, my Motogadget Chronoclassic is successfully using the stock speed sensor in the final drive with rbm's TGPI board.
