Installing an Acewell speedo/computer on an airhead --

The chrome is particularly crappy. The whole thing is pretty crappy. I recently bogged up the holes and painted mine with matte black epoxy enamel and it came up pretty good. I have also fitted separate idiot lights, since I couldn't see the LEDs in the Acewell on sunny days. The hole for the speedo is ~ 85mm diam.



The bakelite knob is from an old gas stove - I epoxied the key into it, but it has since broken, so I am back to an ordinary key. The ignition switch that comes with the bucket is a car type one with a spring loaded starter. I like it.

O, and unless you can find some /5 ears to suit the longer bucket, you will have to fabricate something. I made these ears out of stainless.

I used my 3w park lite in my headlite as the charging lite. it isn't used for anything else & you can still see if it's working albeit by standing on the pegs & balancing over the bars - bit of fun t the traffic ltes

Also When you say "signal divider" do you mean SPC-1.0 ? I have mine set to SPC-0.5

Tete, I did not get a chance to look at my bike or schematics, but I think you can try to connect the white wire from the sensor to the blue(?) wire to the Ace - not sure about you Ace model - and test. Then connect them both to ground and test.
The signal divider (P-001 on my Ace) should be set to 1 (one), i.e. 1 turn of the speed sensor per 1480* mm of tire circumference (*my number for circumference per 1 rotation of the speed sensor). Your tire number may be different, based on final drive ratios, tire brands/size, etc. Sounds like your your Ace instructions (settings menu) uses "SPC" instead of "P". Tell me you Ace model again and I will download the instructions - maybe I can be more helpful.

Mine is the 2853 model. With S-11 sensor

[some_guy]

does anyone have the speed sensor installed and set up right? i cant seem to get the speed right. suggestions on how to calculate the value correctly?

I have an R90 with the S-11 sensor with the 34/11 rear gears and I found that 1480 worked out within about 3 mph over my GPS at 65mph.

Thanks. I had 2001 in there. somehow thats what i came up with. was about twice my actual speed judging by traffic. so i halved it. seemed to be about 15 under then. howd you come up 1480?

edit:33/11 final drive on mine so its probably different. defiantly gets me closer though.

Fair warning, I am a geek....I took the formula from Snowbum's page, figured out what the speed would be equal to at 3500 RPM, and then checked where the speedo read from there. After making adjustments until it was a couple mph high, my wife suggested that I toss a GPS in my tank bag and check my work......she is the smart one in this marriage, I guess......If my math holds up, you would be about 2 mph lower than mine.

If i'm understanding that right, and my initial measurement of 2001mm was right, my setting should be 1382. I'll try that out tomorrow.

Did my headlight eras as well. Also install a tachometer in the bucket hole not an Acwell.

Anyone care to share with me how they wired the s-11 sensor?

This would be a HUGE help to me. Also is everyone simply using high temp grease in the tachometer cable hole in the front of the engine?

Thanks

there was no wiring for me. the connector on the sensor plugged into the connector on the speedo.

I tried that and got no signal. Hmmmmmm .....
