95 K75RT > K75S ...
« on: February 15, 2023, 07:46:45 PM »
Just about done with my latest and last bike build. Moving back into cars and trucks after this one is done.

My 92 was a lot of fun, and this one has been a lot of fun.

One question re: wiring

Does anyone know where this connects? I have BEP 3.0 and Motoscope Pro and Breakout Box B, but don't have an RPM Signal.

Pulled my harness ages ago, so can't remember where this plugs In... and don't see the female plug anywhere. I did however label It... "Ignition Signal".

Once I had a Collie pup. Dug a hole and covered him up. Now I sit there by the hour. Waiting for a Collie-flower.

The tach wire to the cluster is a black/blue wire from the #1 coil.

Thanks,

For some reason my BEP 3.0 isn't picking up the Speed or RPM in the correct spot.

I hardwired the Yellow wire from the speed sensor to the Motoscope Pro and I am picking up speed now. But when I hardwire the Motoscope pro to the black/blue wire it picks RPM up when I crank the engine, but when it's running the signal goes back to zero. Literally the last wiring to do before deciding on rear lights and painting the bike.

Pulled the trigger for the motogadget ignition signal trigger sensor just to get this thing done.

Well she's finished and up for sale.

Wife gave me the green-light to build my dream Porsche but the bikes had to go. It's been a blast learning how to wrench on these amazing machines.

Should do the 911 as a rock crawler?  Would be a shame to keep it stock.

Would be cool to chop the body and put it about 3 feet in the air with 36" wheels and big rock crawler tires.  A big roll cage, winch and light bars.  Yeah!

Nothing wrong with Porsche but two wheels beats four wheels hands down. I'd rather be sitting on a bike leaning over with an engine between my legs than sitting in a chair turning a wheel.

Ha, the 911 was going to get an LS engine until I found a low mileage car being parted out not too far from me.
