Ignition

What do you guys think of a service honda cr500 ignition on a 370 sphinx.  Lighting coil is my concern. Would this be as good as a cr250 ignition or not.  Thanks Jim

what are you doing with the bike? what kinda of riding and fuel choice?

[363 stroker]

It will be on 110 race fuel.  Normal use.  Trail riding, dirt roads, a little bit of dunes.

[motofool250r]

should be just fine the cr250 ignition curve will be better but probably not that noticable for your application.

i also have a 150watt stator for the cr250 ignition that i will get some videos up and some more info here shortly

Do you think it is an improvement over a trx ignition.

You will need a custom made adaptor plate to get it timed right rsss396 can tell you how he really knows IGN s

I have an adaptor plate.  This is supposedly a bdt cr 250/500 ignition.  But I think it is a service honda cr 500 ignition.

It looks exactly the same.

x2, rsss396 is the ignition wizard.

I would be interested to know what the timing curve looks like on the service honda ignition.  

I wonder if the company you mentioned selling the lighting ignitions was just buying them from service honda and reselling them?

I would be interested to know what the timing curve looks like on the service honda ignition.  You will have to modify the std esr stator plate because it has a ring machined so it lines the stator up centered around the crank/flywheel.  To use the service honda stator you will have to grind the ring off because the cr500 stator does not use the ring.

This is what I am wondering.  The ignition came with a mounting plate to bolt up but no Instructions,info,wiring diagram or anything.  It looks "exactly" like the service honda kit.  I am going to try it but was curios on peoples take of this or if they tried one.  I am told this is "custom" and very close to the cr250 curve but I am hesitant to beleive that.

here is some talk about it on the cr500 forum

curious if the stator plate service honda uses can just be swapped out with a cr250 plate. The cr500 guys machine the cr250 plate to work on their bikes or use the cr125 stator which has the smaller crank seal like a cr500.

I guess members only can read the post.

I think so.  I could not read it.

I copied a couple posts about it and some video, not allot of info on this yet but I guess this is better than nothing

New starting vid of the SH Ignition available next week.

"This video shows the 2 different ways to start our newest version of the CR500 digital ignition. First way to start is a fast full top dead center kick starting at the highest point in the kick stroke. The second way is to perform 2 kicks back to back while keeping the engine rotating. The reasoning behind this is the digital ignition initially fires on the second revolution rather than the analog ignition which fires on the first revolution."

Its almost 100 watts right off idle
That said , yes right at idle(depending on where you are running idle)
if you run AC you might see it dim or brighten as you blip the throttle right off idle.

Anything above idle, is ful on bright as the wattage of the bulb you are running.
 i truly doubt you can see any difference in headlight  output at all...
unless running some huge kit  for desert racing ,or a street kit with signal;s taillight brake light horn etc, where a DC system with a capacitor or battery is typically used even in any OEM street bike to stabilize the system somewhat.

The system was always designed,by Electrosport for us,  primarily for lighting
as Eline had long ago dropped their external unit.

That unit as a good one!  I had one and liked it!
but it hasn't been available in a long long time.
and  it was 2 separate circuits  (two 100 watt circuits on one system ,isn't the same as one 200watt) so that often confused folks as well.

Ours is 130 watts and it comes up fast, right off idle.
I'll try to put a vid together sometime

Here's the headlight with it idling. Battery was stone dead after I turned on and left the switch in power position with my Duran style hands of stone. http://www.youtube.com/watch?v=lyWSUp_sIO8

( a small battery is recommended with the system to prevent flicker in the lights)

Thought I would post up Jim's BDT CR250 ignition with a lighting coil timing curve compared to the 2001 cr250-cr125

System seams to be of a nice quality not sure who builds it but it does seam to be the same manufacture Service Honda uses for the cr500 ignition.
When I went to the Service Honda website the wire schematic matched perfectly and looks to be simular.
