Hi DDave,

I believe Honda handed off manufacture of replacement CDI's for the 600's to
Shindengen. I don't know exactly when, but I was left with the impression
that Shindengen tinkered with advance, among other characteristics for
easier starting and more power. I think I read about it on the web
someplace.

You say the 650 needs 100vAC, the 600's supply alot more with each kick, I
got figures in excess of 400vAC P-P with a working CDI on my XL600R 1987.

Out of the repair manual:

Ignition timing initial 1983 6 deg btdc @1200rpm
after 1983 11 deg btdc @1300rpm
Full advance 31 dec btdc(a)4000rpm

Hi DDave,

I forgot to say my XL600R runs on the stator, I've got a dead battery and
the only affect it has is on the turn signals-they blink real fast.

Thanks, Joe.

Good info both posts.

The 100VAC was a placeholder number someone bandied about.

The XRL just gets 12V to the CDI, all the time. Yet, it is reputed to
pop-start without the battery.

I have to confess I'm not sure if the XRL has a 'magneto' like an
XR600R that just has a rectifier/regulator on it, or if it has a 'full-
up alternator' (meaning "something other than an XR600R magneto" in
this context), minus the variable field-coils, of course.

This test would be easy to run, if I could power a 600R CDI direct off
the XRL 'alternator'. Word on the street is, at cranking speeds,
there's not enough juice.

DDave,

I can send you my used but working spare 30410-MG2-892 MODULE IGN CONT if
you want to investigate. I'd like it back.

I wonder if the part number is the same? But, I suspect the 650 can run w/o
the battery. I don't remember if there was a kick starter in the ones I
looked at years ago.

On an unrelated note, there was a 1997, I think, XR650L that wouldn't run,
but cranked on Craig's list for $750.00 here in over-priced California.

I spent a restless night on that one, don't have a garage.

I'd say, look on eBay for pictures, maybe the connectors are different. But
this module has two Molex type connectors, the connector with two pins is
the trigger and the other connector is key on, the AC from the stator and
ground.
