The manufacturer of your unit need to employ an accurate translation for their instructions - those are gobbledygook.
My thinking is:-
If one set of points operates two cylinders with a wasted spark you are getting four signals for one 360 deg of rotation so setting 4 on the left side of the first table (4C-8P). If its a 4 lobe unit. or is it setting 2 FFS I'm lost already but...
Presumably if you get the setting wrong it will read either half the true revs or double .
Either way you should get a reading assuming the power supply wiring is polarity correct and earthed.
Update:- I keep changing my mind between setting 2 & 4 either way I cant see why you do not get some sort of output givig a reading

I wonder if this would work

Here's the set up guide. Mine is an analogue rev counter Ted, I'm thinking of using the wrap around HT lead method of set up to see if that works but I'd rather the hard wired way. There are no instructions for wrapping around even though a wire is supplied for it

An electronic rev counter works by converting the rotational impulses into either a digital or analogue display.
A rev counter for a 4 cylinder car will not work on a 3 cylinder one though manufacturers might fit a circuit so it works on both. I fitted an Audi 100 GL car rev counter into my old Mini as both were 4 cylinder vehicles.
I assume yours will be specific for a 4 Cylinder motor cycle that uses the wasted spark system - not a distributor

A "standard" electronic tacho will count 4 lt pulses for 1 crank revolotion, the honda coil will pulse twice for one crank revolution so readings may well be wrong, also with the dyna there is a different amount of "dwell" or coil charging time which may afect the tacho operation, i cant comment on that as i understand electrical dohickies but not elctronical ones

Wow, I thought that was a bike museum, what a great collection of bikes lots and lots of tinkering in the shed types.
Cheers

I'm not sure I understand Ted. The instructions are woeful, in the setup guide you have to select for 4 stroke and 4 cylinders by selecting options that go 0.5, 1, 2, 3, 4 but on my gauge there are .5 increments that don't relate to anything in the instructions. It's to chose the number of ignition per cycle. Clear as mud to me.

If it works on the LT side of the impulses will it not be related to the number of sparks generated for one crank rotation?
Not as such affected by the HT coil side?
19
That's pretty cool. I do wonder though what the crash protection would be like as not much distance between the driver and the front of the car.
Very good idea though and this is what I think EV's are best suited to, urban short runs and considering these are the types of journeys most people do they would be ideal especially on London and other cities.
The price though, that's the killer.

Hi,
I purchased these 'bolts' via ebay as they were stated as suited for a 400/4, there are too small!
Got a refund and told to keep them as they did not want to pay the return postage.
I don't have a use for them, happy to send onto someone who can use them.
I assume they fit smaller models than the CB400, sizes in the picture.
Don't want anything for them, better they are used rather than scrapped. Feel free to make a donation to the forum.
Michael
