hour meter quick ??

19 posts in this topic

ok i just got my hourmeter and going to install it on my bike today but im just wondering if the tape they give you is strong and not going to rip off..

could i just drill and tap into my frame by the steering stem so i no it wont come off. or is that a bad idea?

Installed mine last nite. Used the two zip ties to attach it to the cable running on the left side near the stem. Probably a bad idea to drill the frame.

I drilled and tapped mine into the right side of the frame near the steering head. I do NOT trust that tape, as it used to come loose constantly, despite carefully cleaning the frame prior to applying the tape.

If the frame is 100% clean, the tape will never come off.

I made a bracket that it mounts to and it uses the front tank bolt. A company makes the same thing. Just a peice of 4mm aluminum, tapped for the meter and a hole for the mount, bent at about a 20 degree angle.

Use zip ties and tie it to the throttle cables... I wouldn't drill a hole in my frame, that part of the frame goes through quite a workout.

I need some help. Maybe someone can tell me what I did wrong. I mounted a Yamaha meter on my WR450 last night and it doesn't appear to be working. I realize that it won't show time after just a couple of minutes of run time, but it would not show rpm's...there was no change in the display from off to running. The directions on the package said to make 4 or 5 wraps around the sparkplug wire. I made these wraps around both wires, right where they go into the connector that plugs into the spark plug/coil. Is this correct? Or do I just wrap one of the wires? If so, which one?

Thanks in advance.

I wraped my around the sparkplug boot. also did you get a TACH and HOURMETER or just a hourmeter?

Its the Yamaha hour meter...don't have the part # with me right now. I thought that it said that it displays RPMs while running and cummulative runtime when the bike is shut off.

Did you wrap around the boot where it's down inside the head or above the head?

With the late model ('03 and later) YZ/WR using the coil in the plug boot, you need to wind the wire around the barrel of the coil assembly below the seal on top of the cam cover. The harness wiring above that point are low voltage, and don't produce a strong enough signal to trigger the tach/hour meter.

Thanks Gray!! Does it still require 4 - 5 wraps around the boot? Would it be best to secure the wraps with electrical tape or ?? Surely a there isn't room for a cable tie, is there?

Now I hope that I didn't cut the wire too short...

3-4 should be enough, but the more the merrier. It should stay put on its own.

If it's too short, splice on a piece of insulated solid copper the same approximate gauge, and use that. Leave the splice on the outside.

Thanks again Gray!! Once again, you were a big help. Both the YZ and WR now have functioning rpm/hour meters!!

Also, the YZ fired yesterday after about the 6th kick...after a new piston/rings and intake valve replacement...my first foray into 4 stroke maintenance. A big THANKS go to you and all those who post helpful info here.

Also a big thanks goes to my local support group...the Maz clan...even though they bleed red...
