I’ve searched extensively on this forum, the duke 390 forum, and the internet at large, but still have some questions. There is surprising little in the way of real information, other than complaints about how difficult it is to access and remove the unit itself.
Please don’t hijack this thread making an argument about the wisdom of removing the ABS. I’m not suggesting anyone should, but I am, and I want to do it properly, efficiently, and as elegantly as possible.
Street/ Track bike. I want to bypass the ABS, at least for the front. The lever feel is terrible, and others have said that it’s due to all that extra plumbing. I’m believing that’s so. It feels like a badly bled system. So simply switching the ABS off is no solution. I want to retain my Speedo/ Odo. I wouldn’t mind retaining ABS on the rear brake. I never use my rear brake other than if I inadvertently find myself off road. But if it’s not possible to bypass the front and retain the rear, no problem.
So here's what I want to accomplish-
I just want no ABS, and a functioning speedometer, no dash errors. Optimally, I'd like to lose that front ABS ring.
Please, any explanations or assistance, assume you’re talking to an 11 year old, as that’s my level of understanding of electronic/ software systems, although mechanically I’m not afraid to tackle anything.
Here’s what I think I understand. Please confirm or correct.
So because the speedo gets inputs from the ABS unit, the entire unit can’t be removed without losing the speedo function.
But if I only block off the hoses and leave the unit in place, my speedo will still work.
If I block off the hoses where they enter the ABS unit, and run houses direct to the brakes, will I get an ABS dash error?
If the answer to that question is “yes” ……
(otherwise what directly follows is irrelevant)
The simple solution is to unplug the ABS dash light. I’ve also read that you can use a resistor to “fool” the ECU so no error is detected.
What ohm resistor, and where does it go?
Since the ABS unit is in place, and plugged in, I’m assuming this resistor would need to be spliced inline into a wire that runs from the ABS to the ECU. I can find that plug, but which wire is it that requires the resistor??
Now, what if I want to lose the front ABS ring?
I’ve read that (in order to remove the front ABS ring) some people have extended the front speed sensor cable, the magnetic pickup, so it’s now getting the signal from the rear wheel. Is this possible?
What little I think I understand of ABS, it operates by measuring the differential in F/R wheel speed. So if I ran the front speed pickup to my rear wheel, then the rear ABS wouldn't work anyway, because the ECU would be fooled into thinking both wheels were at the identical speed.
Correct?
Various suggestions about using parts from the models, RC200, etc, so that the front wheel pickup can be used running off the magnetized rotor bolts. This would be the most elegant solution, if it is doable.
I'd like a solution that enables me to remove that front ring, if there is such a solution.
I basically want to know the best way to go about achieving no front (at least) ABS, while retaining my speedo and having no dash error. I’d like to know what the most elegant solution is, the solution that requires the least amount of irreversible changes to the harness, plugs, etc.
Someone out there knows this stuff. I’m hoping you’ll contribute, I can’t be the only one who wants to know about this stuff, and is slightly (!) confused.
thanks in advance!
