Ignition dilemma

[Trigger]

Thanks simon for your time trouble and knowledge.
Very much obliged
David

Are you learning about electrics mate

Trying to trig

Good, then you can teach me in plain Irish

I remember bowyer in the 70s like harley over rated and over priced nowt wrong with standard set up.
Cheers

ps even now wont be converted so dont bother to

Yea Matthew,

I'm honestly with you all the way on "keep it simple"; Honda did a great job. My personal failing is I enjoy electrics / like to tinker.... and so any excuse. (& anyways, 70's electrics is just like plumbing... without getting wet!)

In Norniron's case, he's fitting up rated coils... I don't know the spec but have read elsewhere that various aftermarket coils are somewhat more beefy / power hungry than OEM. There comes a limit as to how much current you should reasonably expect a switch designed to a lesser spec to pass... and so a relay becomes a necessary evil in such cases. 

In the case of a breakdown attributed to a relay failure in this case.... a very simple roadside fix would be to disconnect #86 & #87 from the relay & then connect them together.... the kill switch will now feed both the coils & Electronic ignition directly.... ie we're back to the original wiring. Perhaps David, mark those two connections with dayglow or something & put a connector spade in the toolkit! (tho' modern relays rarely fail)

(or #30 to #87 would work... the ignition will now be permanently live... ie if the kill switch failed this would also be a get-you-home)

Simon.

The Boyer system I fitted to the CB650 was a complete system, coils an all. Not one item of the Honda set up was retained. It cost £170 and was worth every penny. I could not believe the difference.
The engine started up instantly as you pushed the button, no delay.
The exhaust sounded crisper.
Throttle response was positive with no flat spots or hesitation.
Considering the CB650 came with electronic ignition as standard the difference between the two was a revelation.
It was like having an extra 100cc added to the bike.
I've used strobes and dwell meters to set up points/ignition but it doesn't matter how good you are you will not get the same performance improvements that will come with a full electronic system. If you take you time and put it in carefully you can then forget it, no maintenance required.
Don't be a dinosaur, go get a Boyer.

Each to there own some do points no problem some DONT

Genuine Honda points obtained and fitted,also replaced capacitors. Fired up just great and runs fine. Thanks again to all who responded. Generated quite a lively debate but points won on points. I'll get my coat.............

Well there you go rest my case

Hello chaps. In a bit late.  I have the Hondaman unit (from US site)  in my bike and I would recommend it. Cheap as well as having a great warranty. I noticed how easy the bike started when I installed it.

Yes les,i think i will order a few of these.only read good things about these,no bad

I can not see the point in using the Hondaman system when you still have the points. If the backing plate warps it has to be replace for it to work but, i am still not sure if the points are worn out if the Hondaman system will still work. So it seems like the Hondaman system is just a boost to the points.

Trigger the Hondaman system drops the points voltage tp a negligible ammount so the contact surfaces dont arc or wear, yes the heel still wears but after initial bedding in that too is normally negligible

Cheers Bryan, that is a bit clearer on how it works. I knew someone that had problems with his points and bought one thinking it would cure all this problems. It was still the same problem until he fitted a new plate and points. This is why i said that i could not see the point when it worked out a little expensive when you take into the Hondaman system and a new plate with points. When he could of fitted a Dyna cheaper.

Thanks for the explanation Bryan. It has helped me understand a tiny bit more of the dark arts world of electricity. I must admitt when I ditched points for a boyer system it was to cure an intermittent problem that was probably for more to do with carbs. However I have yet to re visit the issue and apply my new theory and will probably not do so as I am in any case swapping parts as part of the rebuild to go slightly more original.

If you are old enough you may remember "Sparkrite" ignition systems for cars, i put one on an escort van and didn't touch the points in 4 tears
