Team UnorthoDUX Ducati based land-speed racers New pic pg 19!

You could try swapping out a different set of timing gears to something less aggressive of a signal.  The 48/2 gears have got to wreak havoc on that input module for the ECU...

[Dirty Duc]

It really seems related to the shielding on the sensor line or something. On the blower bike I had to make sure the spark plug wire was far enough away from the sensor wire or I got all kinds of interference.

The ECU is usually used to read a 60:1 trigger wheel at crank speed. 48:2 shouldn't be that bad at cam speed.

Today was mostly good. Lucky is running after a few hours of cleaning methanol-chewed aluminum out of everything... i even took video, but the power is out and the camera battery died so i can't post it.

Note to self, run gas through the system at the end of the day.

Later tonight, video will be available at:


I spent the day troubleshooting fuel problems... the pump would randomly drop pressure for no apparent reason. Checked the voltage and it followed the battery/regulator expectations, so I swapped it to an external setup I had laying around. No video of that because I am out of the appropriate fuel.

It was a bit disconcerting when I realized the clipons hadn't been tightened enough... I remedied that forthwith.

So most of the weekend was spent on non-bike projects... but I did build two new brackets to steady the fairing in the middle.

Yeah, the news has been cautiously optimistic over the past month or so.

Note the plug for the mining company's efforts... got to keep the message positive, more flies with honey, etc.!

I know right?

[Dirty Duc]

There's still plenty of riled to go around, though... can't go too far on the topic without bumping into the "P" word.

Bought some materials on Tuesday to make a more controlled testbed. Almost all of it in my possession, but fabrication hasn't started yet.

[Dirty Duc]

So, anyone from here going to be out there this year?

It's crunch time!

Things left to do:
Front fairing filler - aluminum
Rear salt spray deflector - stainless.
Tuning - build dyno
Front fender "wrapping" - aluminum
Pack the trailer
Drive a bunch of miles
Race
Drive home
Unpack
Clean salt off

"Build dyno"?

[Dirty Duc]

The dyno... kind of redneck, and initially won't really give measurements. I will be using the datalog/computer hookup to do the analysis. Tunerstudio comes with some pretty powerful analytics if you can plug it into the vehicle under load.

In a car that kind of means sitting in the passenger seat while your buddy drives it around for a few weeks. Hard to do that on a motorcycle, especially one not legal for the street.

So, about an hour away (in the nearest thing that passes for a city) there is a  scrap metal recycler that resells stuff for not much more than scrap prices. They don't keep any kind of formal inventory, and they won't hold anything unless you pay for it.

We drew up tentative plans, and went and wandered around their yard for about an hour looking for likely bits. 96 feet of 1 1/4" square tube, about 24 feet of some kind of fancy ramp material, and about 24 inches of 13 inch ID 1/2" wall steel pipe. Now I'm just waiting for the last bits to follow my brother in law down from CO on Monday. A couple of manufactured home axles with two-piece wheels and electric brakes.

Which puts me into this contraption for under $200 (not counting cut-off wheels and welding supplies)... That's about a hundredth or two of the price on a regular inertia dyno, and mine will have (an as yet undetermined) capacity for loading/steady-state.

Very cool.
