A Labor of Love; aka building a Rocket III Speedster

[Quickie69]

So here's the primary damage:

Shifter side foot rail "slightly" tenderized.


Shift mechanism got a good "customization", now abstract art!

Whole engine shifted about 1" to the right in the back and about 2" in the front.

Steering damper got whacked by the engine, pulling the nutsert 1/2 way through the steel.


Brake side rail got pushed up some, but was mostly spared by the ZH2 bars doing some heavy lifting.

I've got a left hand foot rail laying around...

So onto another part of the project now that some other stuff has been sorted:
OEM Front and Rear ABS rings - 60 gaps.

Would appreciate a logic check but...

It seems to me, simply adjusting the tooth count on one of the rings will correct the ECU's observed wheel speeds when using non-OEM sized tires.
So having a 58 tooth rear ABS ring would report to the ECU that the rear wheel is turning 3.23% faster than it actually is, bringing various tire choices under the 5% threshold required for ABS functionality (size pairings like 130/70R17 + 240/55R16 or 130/70R17 + 200/55R17).

Time to get some calipers out and do some CAD

You might be able to just eliminate two teeth, separated near 180 degrees, on an original ring. Doubtful that the ECU would activate ABS with that small of a deviation in count rate. (With an 80" perimeter tire, one missing tooth equals about 1.33" of rotation) A good traction control system might, but not likely with a generic ABS system. Might be cheaper than machining/lasering a new ring.

 

[Claviger]

Good point. I guess it is, by definition, a variable rate input so the interval between voltage events should be irrelevant unless there's some sort of signal smoothing or averaging going on in the software, which I doubt in a Keihin ECU of the era.

Off to grab an extra sacraficial ring then lol.

First replacement parts have arrived:

$19 for a Roadster rear axle....a steal of an insurance policy


Fortuitously found these long out of production carbon headlight buckets for sale on eBay, they're immaculate, clearly they've never been installed or seen the sun:





They appear to be vaccum formed or 2 part bolt-together metal mold construction using prepreg, they're very light and very rigid.

I just scooped up a set of those CF headlight bowls as well. I was surprised to see them on there. The post said 2 in stock (now last one) if anyone else is interested. Seller is motoflipper.

You may be able to use an abs ring from another bike, maybe even a H2Z or some such

 

[TURBO200R4]

i wonder if you could glue a piece of tin foil to tempory test to see if that would work or set a code because of the longer space?

 

[Claviger]

Just easier to grab one off ebay and spend 10 minutes with a Dremel, the non-gap area needs to be ferrous material to generate a magnetic field. I'm not going to be done with the rebuild before next summer so it's not like anything is time sensitive at this point. I also need to figure out an alternate ABS control strategy that doesn't involve the Keihin ECU at all....

Cognimoto apparently bounces all emails back so triple modification from them is out. Can't trust a tech company that can't get a Gmail account to function....

Have another vendor who has taller top caps for the R3, allowing for fully adjustable cartridges and might have +2" top caps, which will correct front end height to my target with the 120 or 130 front tire.

I've been in contact with an ECU manufacturer. I may be getting a bit of a price break on it, thankfully, since this stuff has grown very expensive.

• All OEM Triumph sensors are compatible, but i'll have to add a few sensors.
• Touchscreen 7" digital dash w/datalogging sorted.
• MAP triggered home signal trigger sorted.
• Fueling/Ignition circuits sorted.
• 24-2 Crank trigger VR signal processing sorted.
• Variable rate Traction/Wheelie/Launch control sorted.
• ABS functionality with non-Keihin ECU sorted.
• Pierburg CWA400 electric water pump and rad fan control sorted.
• Short/Long full range trim support sorted via Bosch LSU 4.9 setup(aka the bike tunes itself and not the janky "autotune" Powercommander advertises).
• DBW throttle body sorted, still need to find a compatible 22mm DBW throttle tube/sender.
• Intake modification, to switch to a single DBW throttle body instead of ITBs not yet sorted.
• How to verify ignition timing events to mechanical position not yet sorted and have accurate ignition timing not yet sorted.

Essentially, this will bring the Rocket solidly into 2012 era electronics. It won't have an IMU for cornering adjusted stability/TC/ABS, but it will have something very similar in function to the ZX14R functionality prior to the 2016 update except I'll have full control over how it all works.

Fantastic work Rob!!!! Pure genius!!
