Topic: Q: Best ignition for 1000cc application and street use?

[Austrian_CB]

Hey guys,

my question is as the title says. Trying to figure out the best ignition setup for a 1000cc SOHC engine that mostly will be used for daily street riding.

I was looking at the Dyna 2000 w/ their 3.0 ohm mini coils (trying to hide some stuff on the bike, where the mini coils are practical) but is that one really necessary or would it be overkill?

Any input is highly appreciated, thanks!

If you are going to the trouble of going to 1000cc, you need everything else to be up to task, ignition being a top one. Get a good setup, Dyna, PowerArc, etc and make the money spent on the engine worth it. If you are going that big, you will be in $5k for the engine alone without blinking an eye, so don't cheap out on good parts.

Thanks for the answer slikwilli420 ... i"ll have to clarify my bike was 1000c drag bike before i"m currently upgrading everything inside. New flat top pistons, forged rods, hd chains, studs etc. Engine parts are getting worked on by Mike Rieck as we speak.

Also, the point plate i got with the engine looks like it was an "Accel" ignition with dual points and there is also a a 3-stage flip switch mounted on the plate. Trying to put up pictures now.

Accel ignition

That is a MaxiDwell, I really liked mine on my 836.. the switch is the built in timing light, middle is off.
The light should be siliconed on beside the timing hole.
 Your points have likely been changed, they were  riveted on.
To replace points we used stiffer spring Vette points. On one set the corner is ground off to fit on the plate.
To adjust  timing you rotate and lock plate, to set second set you adjust gap. Check timing in a dark room or throw a jacket over you, when using built in timing light.

Accel made a similar set but back plate is not gold and second point set moves, on subplate like stock.
One just showed up on a 550 build thread.

FwIW I had the  same setup as pictured above, Andrews orange coils. 836 with 315 cam.
 I regularly revved it to 10,500 or11,000.   I sold the Bike with coils but kept the motor .
 I put it in an stock frame with stock coils. In was bummed,  because with the stock coils I thought it would not rev as high or as clean. To my total surprise it felt the same as with the hot coils...WTF..

 You really have nothing to lose trying it.
 
Pic below if what I believe is t AcCel..

Post 3 first pic,if you expand, you can see MaxiDwell stamped in to left of paper tag. You can see Where the points sat. The grinding of points plate may be there as its very close to mounting screw.
Do you have any history of the bike, where raced or how fast ?

My K6 has 1004.7cc, JMR billet block. Stock points (TEC) + Hondaman ign module. Work fine with Dyna 5 ohm coils (black)
It has most of everything else in the engine too. Perfect for street and countryside cruising

I tried 3 ohm coils for a short while with Dyna S ignition. Battery drained really quick. Returned to shop and could get the 5 ohm coils instead.
Avoid Dynatec suppressed ign wire (grey with graphite core). I had one new crappy one with intermittent function tricked my carb jetting for a long time.  Copper wire better. My bike has wires with spiral wound just for test.

I have a Dyna III on my 1000. I built this whole bike from scratch. New wiring harness, ignition switch, etc. I took it off the 900 when I went with the Dyna 2000 on it. I have Dyna 3ohm coils on both. I had battery issues with the 3ohms and the Dyna III with original wiring. The first thing I did after the restore with all new wiring, switches and ignition switch and the 2000 was to check the voltage. I saw the mystical 14.5V and shut her down    The 2000 is somewhat programmable but what I like about it is the built in rev limiter. No more blown engines due to missed power shifts. Hopefully.

based on your nickname, I guess you are from Austria.
I'll recommend then ignitech ignition, http://www.ignitech.cz/en/ a third of the price of a dyna 2000 for 3 times the value: fully programable ignition and easy to use. They have also coils and pick up sensors.

[Austrian_CB]

Frank, thanks for all the valuable input. I'll have to look at the full ignition system if i find the rest of the pieces somewhere ... to the bike, all I've heard from previous owner is that it was one of the fastest bikes in Florida in the late 70s. Which is arguable i guess ... maybe, maybe not. haha

Thanks for all  the info guys.

My bike will also have all new wiring! That's why i'm trying to figure all electrical components to make a proper a nice harness for it.

Seems like people have good and bad luck with the 3.0 ohm coils ... I was also leaning towards the 2000 because of the rev limiter. Blowing up is the last thing i want after all the work  That's why i'm running a digital motogadget gauge with oil temperature, pressure etc as well.

livefast_dieold yes i'm from Austria, now living in Virginia though. But my family and everyone else i know is still back home and i also have friends in Czech Republic. So getting one shipped over here would be no problem. Just time consuming, which is acceptable. I'll have to look into the ignitech later tonight. Thanks!

 I haven't seen mention of the Pamco recently what are the thought on that one? I put one (removed from another bike) on my 836 with a ported head and cam but haven't ridden it much due to an ongoing restoration. So far no problems.

[dragracer]

Personally, I see no reason why a simple Dyna S ignition with hot coils and good plug wires wouldn't be up to the task for our bikes. Unless you have concerns about timing adjustments on the fly, you will never exceed the limits of the Dyna S. Dyna S systems/coils have been run successfully on full dragbikes for years with no real lose of performance. Of course now there are many choices like the Dyna 4000, Schnitz PRo series 2 and the Firestorm ignition system that incorporate numerous features in one box. Very much overkill for street use unless your street racing that is.

I'm not as smart as others on this forum, but I do try to be practical in the parts I use for the application at hand.

[bear]

From my practical experience.
I have used a Dyna S coupled with Honda DOHC coils for many years and never had a failure.
I'm just not convinced ignitions with all the bell's and whistles can be justified for the majority of applications.


Cheers,
Brian

I once said that putting Ohlins shocks on a CB750 is like putting a mink coat on a 10 dollar hooker, and I suppose the same applies to spending big bucks on an ignition, but as much as I love the Dyna S and even my 30 year old Dyna III, I installed a Dyna 2000 on another guys bike and it ran uber-sweet. Having said that, as has been previously mentioned, if someone's spent heaps on 1000cc kits, ported heads, lightened and balanced cranks, CR or Mikuni carbs etc etc, 300 bucks for a Dyna 2000 isn't a big ask.  

[PeWe]

All ignitions will feel wonderful if replacing an old stock point ignition where the points are unevenly set which will cause a really crappy idle and thoughts about working seriously with the carbs when it is just a 15min job setting the ignition properly. (Dwell meter a must)
I hammered the 3 ign plate seats on cases to tighten it up, plate is no longer moving sideways when adjusting the ingnition wich is bad for points gap while electronic ign do not mind when turning it.
Found that tech mod here. The picture has the hammer marks visible. (possible to hammer straight on to wide the alu) http://www.motorcycleproject.com/text/sohcign.html

That 10$ woman can charge >20$ with a mink coat, right?  Even more with coat off!
Keep the points is like NOT upgrading that 10$ woman with silicones, keeping the good looking stock naturals

[Terry in Australia]

Ha ha, the last thing you want a $10 hooker to do is take her coat off mate!

Do not lit too early then

A fully programmable Ignitech module (from Czech republic), TPS or MAP sensor hooked up with some nice coils and a cheap OEM 85+ bike pulse stator + rotor.
The Ignitech module costs 150 euro's or something.
