TheRock said he mounted a Cateye mountain bike speedo on his Kodiak. How does one manage to do this? When its made to mount on a Spoke and fork.

 

i would have to say tape or glue the magnet to your rim, then do the same for the reciever on your brake caliper.

 

I put one on my Warrior and it works great. I epoxied a more powerful magnet to the inboard side of the rear sprocket. More power would allow more clearance to the pick up. Then I made a bracket to mount the pick up to the axle carrier, and ran the wires up to the handle bars. I did have to lengthen the wires though. After a little trial and error, I got the calibratin pretty close. I am not all that concerned with actual speed, more with distance for maintenance purposes. The unit I bought was around $25. My only complaint is that the trip meter is not resetable. I resets automatically after being stationary for 3 hours. If it ever breaks, I will get a better one but, for now it does just fine.

 

Yeah on a 2wd ATV the sprocket is an ideal place for a magnet with the sensor mounted on swingarm. on a 4wd (don't know if Kodiak is or not) you can try soldering/crazyglue a magnet to a car mag wheel weight and that might fit onto the inside of your rim. I had to extend the wires about 3 feet, and once all hooked up it didn't work. I just sort of walked away from it after my nice shrinkwrap wiring, its good to hear yours works with extended wires, so maybe I just need a stronger battery.

Hey what happens when you exceed the speedos limit of 100 kmh?

Rod 86 250R

 

Lets see. 100kph = 62 mph. I have gone 127.3 mph up hill on a stock Warrior and it worked fine. Believe that one will ya? No, seriously, I think it only goes to 2 digits. Like I said, I only paid $25 for it. A more costly one may be capable of 3, I don't know. I have never had the opportunity to ride flat out on a smooth surface. Therefore, due to vibration and trail conditions, I can not actually say I have been able to read the display much over 50 mph or so. In any event, even if one would register 3 digits, in most cases you wouldn't be able to see it. I'm not sure but I think this is the way these things work. The magnet creates an electrical pulse as it passes a coil in the pick up. This pulse is read and calculated along with the tire diameter (which you enter) and converted from rpm's to mph or kph. Now we are probably talking millivolts as a pulse so I don't know what effect the lenght of the wire would have on voltage drop. In any case, I used a bigger wire size when I lengthened mine. Another problem you may have is too much distance from the magnet. I mounted mine by trial and error until I could get it as far away and still have it work (about 1/8 of an inch). The magnet I used is about an inch in diameter and I just borrowed from one of the thousand that were on the refrigerator. All of this is mounted on the top of the carrier protected as much as possible I have gone through some pretty nasty stuff and haven't had any problems in the year that it's been on. Hope this helps you get yours working, they do come in handy.

This should anwser your questions. I have put one on a 2000 Kodiak, mount the magnet to the rear brake disk using epoxy glue.

 

Ahh, moving to a new site. The pics on the above page don't work. Try this one:

Sorry about that. The pics on this page work.

 

Hi,

I typed this once and thought I saved it as a draft but it is gone. So here goes. I researched and wound up liking the http://www.cateye.com Enduro2 Speedo. It is water tight (except for the sensor) and has a setting that does well for slow speeds that works good on higher speeds as well. It comes with a heavy duty cord but it is too short and the mounting bracket is OK but the one (bracket) that comes with the optional longer cord is Much better. The longer cord is not heavy duty but is plenty long. I ordered my Speedo and cord on-line from http://www.phattire.com/ . This unit works via a magnet and sensor. It counts revolutions and according to the distance your tire rolls in one revolution it reads out the speed and other info.
OK, take a look at your front differential housing on the left side where the CV joint hub exits it. Note the three machined gussets. There aren't any on the right side. On my Kodiak the CV joint hub is Green where it exits the differential. I routed the wire down from the left handle bar and laid the sensor in-between the gussets so the tip will hang out over the green part. I used a Hose clamp to hold it down. Not too tight, it will crush the sensor. Snug is good. But first you will want to remove the magnet from the spoke mount bracket noting which side of it was intended to see the sensor. Then JB Weld (2 part epoxy) it to the green hub. What you want is to have the magnet rotate past the sensor as close as possible without touching. Before I attached the sensor to the differential I coated it with silicone to keep the water out. It is not very water tight. Just don't coat the part that the magnet passes.
To calibrate it for your tire size you will need to convert inches to centimeters unless you have a metric tape. What I did was put a piece of eletrical tape on the floor lined up with a peice of tape on the tire. Sitting on the bike I drove it on revolution and put another peice of tape on the floor marking the spot. I measured it and then done the math and entered the number into the Speedo. Instructions on doing this comes with the Speedo. You can borrow GPS or like me, ride next to a Honda 450ES and compare. I got lucky. The honda does not read out speed in tenths. As I rode with him I seen mine go to 12.8 MPH and then his would switch to 13mph and mine too.

See You

AC

This is an article Gordon Banks wrote about installing a speedometer. It is the same speedo I have on my 400ex and it works great.
