Laid her down... Not running. :(

Kyle:

Good news that your bike only suffered damage, and not you too. You'll learn a lot from the experience.

There's a used Dynatek 2000 ignition system on Ebay that'll work on your bike. It appears complete, but it does not include their ignition coils. However, I think the stockers on your bike have the same resistance as theirs, so they should work. Maybe someone else on the forum can confirm this.

Looks like randy probably has me covered, he sent *me* an email before I got one out to him.

Thanks guys.

Without knowing this forum and randy are here to help out, I know I would have felt a lot more frustrated and helpless to the powers that be upon realizing the damage.

Bonus question:

If you had this happen in the middle of Africa and you had to jerryrig it, what is the most minimalist roadside repair you could come up with to get spark back? Is there anything one could do?

On that kind of trip I would have 3 feet if 16 AWG wire and my butane soldering iron in my tool kit. That would address the broken wires. Honestly, With the damage that is shown in the photos, Short of having 2 spare pick-ups, in this senerio I would say a person is SOL.

What's actually inside a pickup? I always thought it was, more or less, just a little magnet and wiring, not much more. (Feel free to correct my ignorance, I really just don't know anything on this one.)

Hey I did that too and have the same busted piece of casing; now on the garage wall - engine bars installed, so therein lies the lesson.
You can get all the bits off ebay easily, but if you're lucky, like I was at the time, an fjer may sell you some for a reasonable price.
Hopefully then its just a bolt it on thing, closely followed by the bolting on of those engine bars.
Ride safe and don't leave it 8 years to change the front tyre.

So, apologies for the delay in follow up. The day after the lowside, I was in a Judo competition (which you can see here:

Houston Open Judo Tournament 2013

if that catches your fancy); well, the guy who got second place wanted to prove to himself that he 'should' have won, and was being kind of a jerk at the next practice, really being aggressive. I started taking offense to how he was acting and got drawn into it, so our sparring became rather... 'spirited'.

And ended with me twisting my knee a bit. It wasn't exactly his fault or my fault, kind of a 50/50 thing. I just wish he hadn't been a jerk about it and gotten me all fired up.

The next day I had to literally crawl to get to the bathroom. I was pretty sure I had torn some stuff and was praying I didn't need surgery.

Thanks to an awesome diet and the fact that I cycle for a living and do lots of practice (and youth, of course), I am recovering ridiculously well, and it looks like it was just a bad sprain. I can already walk up stairs mostly without issue (though walking downstairs is a little more challenging). I think in a couple weeks I'll be right out there practicing again.

Anyways, I digress.

I got my parts from Randy (thanks!) in the mail and started working on the bike today. I was able to remove the rotor without an impact power drill by sticking a wooden sledge hammer handle in between the swingarm and a 'spoke' of the rim--just barely. Was afraid I was about to break my ratchet. Had to stand on it and sloooowly apply weight to get the leverage and force necessary.

Putting it all back together, I noticed that the rotor was actually--barely--grazing the sensors as it spun around. "That's odd," I thought, "isn't it supposed to just get really close, but not actually touch the sensors?"

On a hunch I decided not to start the bike and emailed Randy instead. He confirmed that was true, but was having email problems, so couldn't look at pictures yet.

Anyways, thought I'd put a pic and a video up here of the situation, see if anyone else had some insight as to why this is happening? Everything seems to otherwise fit right, so I'm kind of confused. :?







I have some more pictures on my phone that I can add later.

By the way: you can see that one of the mounting screws for the left sensor is missing in that last pic--I put an appropriate screw in and that did not change anything--and the issue is on both sensors anyways.

[FJ_Hooligan]

It should be a constant gap.  Something is bent or out of round.  Was there any slop when mounting the pickoff plate?  I'd hate to think the end of the crank is slightly bent.

Loosen things back up and see if you can move the plate around to get it more symmetrical

[fintip]

Everything really felt fine going on. The rotor bolt, the giant one I had to nearly break my ratchet to remove, looked and felt very healthy. I have a very hard time imagining that the rotor had enough leverage to bend the crankshaft--which is why it itself got bent, basically until level with the road. It is much thinner than the crank. And the bolt itself didn't even have a hint of grinding on itself.

It is contacting at both sides.

Is there a chance that the gap changed between models, and I have sensors from one series and a rotor from another? I think I remember that something did change down there, because pictures in some manual don't fit what one sees from one model to another down there, no?

[movenon]

My only advice is to remove the rotor and remove the pick up mounting plate and do an inspection from there. Look around those larger 2 JIS screws are for any damage under the plate. The gap should be nice and even when properly functioning. Hoping it will be something obvious.

I see it looks like you replaced the JIS screws with small bolts.. I guess it's assumption that the pick ups are correct ?

What you've got is all early model.  The pickoff plate and rotor are way different on the later models.

[racerrad8]

In this picture it looks like the plate is not sitting into the recess of the case properly. You can see the aluminum at the bottom bolt is wide and it appears to taper down as it rises and looks almost flush with that edge just above the P/U coil. You need to make sure the timing plate is sitting flush against the case and nothing is holding it out as that will bring the P/U coil(s) closer to the rotor.

Is that the plate I sent of the old one from the crash?

This is pretty strange.

The rotor and pick up base were the same part number from 1984 through 1987.  The rotor and pickup changed in 1989 and remained the same part numbers through 1993 models.  So, if you've got an early dual-pickup model, they're all the same.  The fact it's contacting by the same amount on both sides tells me that the rotor is too long or the pickup base is too small.

Hey..wait a second.  If the rotor is contacting both sides by the same amount and you just changed it?  It's either out of spec for some unknown reason or...since it's just one a one-arm rotor swinging by BOTH pickups 180 degrees apart, is it possible the rotor is mounted up slightly off-center?  Essentially making it's radius larger than factory?

I am with Randy. I think the problem is the mounting plate installation or something deformed under it. He needs to pull it all apart and take a critical look.
It will be interesting to find out.
George

[fintip]

Looks like it is, indeed, a bent rotor--the 'new' one, that is, was already bent. Randy messaged me saying that might be the case, as he just grabbed it out of a box without checking. It is subtle, but in person it's a little more clear. Of course, it would have to be subtle--it fits almost perfect, but just barely scrapes it every time.

There didn't seem to be any remote chance that the plate was on unevenly; took everything apart, and was about to film me putting it back together when I realized that the rotor itself was the issue.

Second opinions to confirm (or reject?) my diagnosis here are welcome, of course.

[racerrad8]

Yep, it is bent...

I straight one headed your way on Monday.

Sorry, Randy - RPM
