I just bought a 09 KLX250s. Its speedometer error is worse than my KLR650. It reads about 11% high. The speedometer works by counting 5V square wave pulses sent by the front wheel sensor. I am trying design a simple pulse reduction circuit, using common ICs, which would output at a rate of 9 pulses for every 10 pulses in. I am hoping there is someone on the list that is good with logic circuits that may know of a chip that would acomplish this. Craig Kahler [Non-text portions of this message have been removed]

I used to know how to do it, back when my job title was "Electronics Technician". However, that was about 15years ago and I've forgotten the finer points of IC circuit design. -Jeff Khoury From: "Craig Kahler" To: "dsn klr650" dsn_klr650@yahoogroups.com> Sent: Friday, March 25, 2011 5:58:07 AM Subject: [DSN_KLR650] NKLR KLX250 speedometer error digital electronic I just bought a 09 KLX250s.

OK. I think in order to get a 9/10 output frequency you'll have to do it in at least two steps. First, you'd probably build a "Divide by 10" digital frequency divider as described here: http://www.play-hookey.com/digital/frequency_dividers.html Then, now that you have a 1/10 frequency sample, attach that output to a two-diode odd-order frequency multiplier (or two - for a 1 x 3 x 3 = 9) to achieve the "x9" desired result. http://www.wenzel.com/documents/2diomult.html Hope this puts you on the right path. -Jeff Khoury From: "Jeff Khoury" To: "Craig Kahler" Cc: "dsn klr650" dsn_klr650@yahoogroups.com> Sent: Friday, March 25, 2011 8:32:54 AM Subject: Re: [DSN_KLR650] NKLR KLX250 speedometer error digital electronic I used to know how to do it, back when my job title was "Electronics Technician".

Thick wire + a relay straight off the battery through a fuse: Got 'em both. =) Mine wasn't the one that tested wierd with a car battery, though. I've had three Stebels on different bikes and for whatever reason, each would act a little odd from time-to-time if the temps dropped below 50F (guessing). Let it be warm and small bugs die within a radius of 10 feet when I blow the horn. * eddie *Slight exaggeration. LOL

Thin wiring will not provide all the current it wants and you will have lackluster performance.

a relay to the horn. Your results will be much improved.
