hi guys,
just a quick question. fitted my koso clocks and got the new engine in today. I can't get the rev counter on the koso to play.
The wiring options (theres 2) are
1) Connect it to the positive side of the coil.
2) wrap it round the HT lead.
Option 1 doesn't seem to work at all and option 2 leaves the needle bouncing about all over the place. I was wondering whether anyone had fitted one of these and if so what wiring did they use for the rev counter?
cheers
Rich
p.s. i've also tried wiring up the RPM lead to the yellow/green on the CDI (which i think is what the old rev counter used for rev pickup. Again no joy/
Any help would be much appreciated.

Re: koso rev counter help
Hi,
I have not fitted 1 of these clocks but Craig(guess who) has fitted a digital dash and so has 1 of my mates on a CBR600F, I believe on the nc30 the way to do it is wraping it around the ht lead, I think it has to wraped around the ht lead a certain amount of times doesnt it? and perfectly spaced? I remember Craig having some problems with his but Im prity sure he got it working ok

Re: koso rev counter help
hi there,
i've got it wrapped around the HT lead at the moment. Its a bit all over the place as far as readings go though. At idle it moves between 0-2000 every few seconds. The instructions don't even mention wrapping the wire around the HT lead so possibly thats why is acting a bit odd.
It does mention connecting it to the positive side of the coil or between the speed sensor and the ECU (which i'm assuming we don't have).
On the clocks themselves it has a "lo act" and "hi act" setting as well as adjustments for 2/4 stroke and number of cylinders. These don't appear to have much of an effect.
Does anyone have any idea about any other parts on the bike that may have a pulsed signal that i could try or failing that how many turns etc i should have on the HT lead to try to smooth out this effect. at the moment i have about 8 turns or so coiled tightly against each other along the HT lead with the end of the wire towards the plug.
Cheers

Re: koso rev counter help
Hi Rich,
I have finally found the sheet I was looking for. I guess that your clockset was bought secondhand? These are the fitting instructions from the KOSO dash I have, mine being the fully digital one (sweeper rev counter) though I guess should be the same electrical connection etc as yours.
With mine I have taken the RPM wire supplied with the clock set (should be the only connection with a bullet one end and a spade the other end).
Connecting this to the clockset, I took the spade conncetor and soldered it to the black wire of the rear coil (which I believe to be the connection for the coil with reagrds to cylinder one)

Re: koso rev counter help
Let me know if this is as you have done/whether it works etc and we can go from there.

Re: koso rev counter help
.
i have that one installed in my bike and it works ok....
http://www.youtube.com/watch?v=Khs7VH7OdTk" onclick="window.open(this.href);return false;
what i did is i used the existing rev cable (going to the OEM clock, i forgot the color code) and connect to the rev cable of KOSO.
after setting the clock to the no. of piston, and no. of stroke, and works ok. but theres seems to be a problem, the counter is little bit "delayed" on its reading, and looks like it have a glitch on the 3Krpm where it stays there for a while.
I went to a bike electrical shop and ask for a second opinion on how to get the meter work perfectly. what the mechanic did was he tap the KOSO rpm wire directly to the rpm wire of the CDI. after several testing, the "glitch" of the meter still exist, poor response of the RPM needle and staying a second on the 3k rpm.
we tried testing different setting on the KOSO meter, and found the answer. No. of piston - 4, No. of Stroke - 2
with that setting, the RPM became responsive and exact reading (like the OEM), and no more glitch on the 3k mark. downside, the RPM drops very fast as you deccelerates.
by the way, wrapping the RPM wire to the spark plug wire gave me a poor signal.

Re: koso rev counter help
hi guys,
thanks for that info. I think i've tried both of those with no luck. I've connected the brown wire with bullet connector to the yellow/green wire which was connected to the original rev counter. That didn't seem to do anything on firing her up. I've then taken a wire directly from the brown wire on the clock loom to the point where the yellow/green enters the CDI in case the wire was broken in the loom somewhere. No joy again. I've then taken a wire from the brown to the black/white wire on the rear coil. Not soldered it but made up an arrangement similar to method B on the instructions you've attached. Again nothing at all.
The only way i can get the rev counter to react at all up til now is wrapping around the HT lead.
Are there any other wires anywhere that will produce a useable pulse that i could have a go with (i.e. try something like method C on the instructions?)
I'm a bit stumped i have to say as usually i'm not too bad with electrickery!
P.S the only bit i'm missing is the supplied wire from KOSO to make these connections so everything tried above has been done using standard wire that i had in my toolbox.
Also i have an extra option in the RPM menu. As well as specifying the number of cylinders and stroke i also have "hi act" and "lo act". This isn't really mentioned too much in the instructions. I've played with both settings and it doesn't make a lot of difference.

what kind of koso meter you got there by the way, RX1N, RX2N or RX2????

Re: koso rev counter help
its an RX1N i have. may try to get out there and have another play about with it today. I'm going to see if the original rev counter works with the yellow/green wire just to check i havent damaged that output in some way.

Re: koso rev counter help
hey guys. Finally solved this issue!
Theway i did it was to connect the brown wire to the white/blue wire coming out of the right hand side of the engine. Its the positive signal wire for the CDI. You then need to set the dash to 4stroke, 12cylinder and hi act.
No idea why taking a feed off the positive side of the coil or using the green/yellow off the CDI didn't work. All i can think is that the original rev counter works on voltage range rather than pulses?
Anyway thought i'd post the solution as a reference for others. I don't think its critical which wire you use coming out of the engine as they should theoretically all have a positive pulse to them.
cheers for the help

p.s. i need to test it first but i've used an aftermarket speedo pickup which if it works i will post details on. Its impossible to see on the bike and is really tidy.
