I was told the original 28mm Keihin I started with was off a 2-stroke, the internal parts look the same as the 24mm OKO.

So they have the same number of holes in the holder in same places?

I will have to re check that but yes I think so.

I read through your links and people report that after a bit of a fiddle they did get their OKO's to work well on their strokers so thats encouraging.

Bummer it also looks like the CR85 has at least 4 Holes as well. Not sure re the KX100.
Anyone got a PWK off a KR1s?

Chucked in the Sudco Mikuni stuff as well.

The soft rev limiter is currently set at 12500rpm. Previously there was no rev limiter allowing the motor to rev through to 14k or so (no rev counter so this is all going by ear and power drop off and knowing the old dyno curve). The delay coming back onto the throttle is noticeably worse the harder the bike is revved, so while the problem existed last weekend it was almost minor compared to how it was with no rev limiter.
Now before some says "why dont you set the rev limiter at 10500" ...

I'll say it i was thinking it before anyway couldn't the rev limiter be set to work to a lower level at a per-determined TPS position (say 25%)
That way it should only effect over run.
But my thoughts were there was a excess of fuel (Rich mixture condition)that needed to be burned off before thew engine would respond when coming back onto the power from a slower corner high over-run revs condition?

Below Bert or Burt 1972 ish

No, the IgniTec software does not allow for tying the revlimiter to a TPS position and rpm, its rpm only.

The OKO has four holes each side.

Unrelated but I bought an Ignitech ignition off a KB member for my BMW R90, had a few questions about why the program would freeze up.....no replies to email or PM.....got it sorted thanks to Ducati forum.
Nice bit of kit though.

What was the answer to yours freezing up? I am still struggling with ours.

PM sent.

Are you the guys with the dyno Darren told me about.....?
My BMW needs some dyno time to get the jetting/ignition right.

I am sorry I didnt reply to the questions about the software freeze ups.
I emailed Ignitech about it, as I have been having this issue of late, only since Ignitech have supplied a "one for all " Windoze driver for usb.
Never had a problem previously, except when using USB in real time with the motor running.
That is always to do with RF noise going down the usb, and is usually fixed easily enough.
But I have had no real helpful info from them about constant freezing up for no reason, I havnt been able to solve it myself, so if there is a "fix"
then many of us would love to hear about it.

A reply would have been nice......even just acknowledging you were following up...anyway

OK, fitted the unit , my mate made up a mount for the pick up...set gap to .6-.9 mm
Bought a usb to serial interface from Jaycar for $34.00
Set up the base advance, set up the laptop , you could see the crank speed on the screen,
As soon as the motor started the screen went " no pc connection' and froze.
Tried all sorts, running unit of separate 12 volts to starter motor
After what seemed like hours gave up.....
Next day as a last resort went to Repco and bought 2 RESISTOR plugs.....like that was going to make a difference......
Well it did and it works.

Running dual output coils as was going twin plugs....so earthed at the moment as not needed.

So there you go....its in the Ignitech FAQ but only as an aside....

Now I just need my FXR 150 to magically transport itself from Napier to Auckland and I'll be sorted...

OK, that is what i was saying about it is easy to fix usb communication issues when the motor is running - I didnt realise that was what you were having as its easy to fix.
I usually tell everyone that you MUST run resistor plugs AND resistor caps, must have forgotten with your project.
Or I have tested using spiral wound coil wires,this works real well and means you dont have issues with unreliable resistor caps - but you still must use resistor plugs in any case.
What is hard to figure out is why we are getting freeze ups without the engine running.
Still dont know.
