but it needs 12v DC to work. :D
Byron,

Is that from the Honda NSR125 or the 250 or the 400 (or all of the above)?

So does the KDX fit as well? Are both the Honda and the Kwacka rev counters electronic off the ignition or off the AC lighting circuit. If it is off the ignition, is it a wrap-around the HT lead, or the L/T input?

I'm keen to fit a rev counter on the cheap, and still cross for letting that Krober slip by me on ebay last month. It only went for £23. :roll:

They're off 125s.
work off the pulse from the CDI.
I was just using the KDX electronics in the cut about NSR housing
but any two stroke single cylinder bike should do
if buying clocks from ebay, do check that the tacho is actually electronic rather than cable driven, even some NSRs had ccable tachos.
I didn't check once :oops:
a krober for £23! I'd have gone for that too, but then the last year of R&D would have gone to waste...
the hardset part for me has been getting a decent 12v DC from an AC stator; if you're running a battery you're laughing.
be interested to hear any news from anybody else using a bike tacho
