Here's the senario, Seems to start out fine, shows speed and shifts fines, run it down the road at high speeds and speedometer shows 99 mph, it will not shift down after reaching 5th gear , you have to shut the key off every time and then use the e.s. to shift back to neutral to start engine again. It will shift fine at low speeds now going thru the woods, etc but the speedometer will not show 0. After I shut off the machine (lunch break) for about an hour and restart speed will once again show correct mph, only until it warms up and I go over that magic speed of about 25 mph down a road or something for a long stretch. I have been told speed sensor, crankshaft sensor, but I dont have $100 for each part to try and my thoughts are an electronic component (zenor diode) faulting out.
Does anyone have a surefire fix for this, I see people out there posting on this constantly with almost the same complaint.
your help will be greatly appreciated.
:rolleyes:

If you hear it try to shift but it doesn't complete the shift I would first clean the shift control motor , we get a lot of older ESP models in that have a lazy shift motor mainly because of brush wear and black/dirty commutator bars on the armature ..

Honda says the maximum time needed for the shift dogs to match and make full engagement is 34 milliseconds so the ECM is programmed to provide power to the shift control motor for 70 milliseconds , so when the shift motor gets a little dirty and slows down a little then you will have to push the shift button a couple of times to shift into some gears

So rather than making a new thread I will bring this one back to life. I am having the same problem with my ES. I am not having the issue with the Speedo though. I am going to pull everything apart tonight to clean it.

What I was wondering is if anyone knew of a service manual for the 2000 Honda Foreman? I have been poking around but haven't seen one.

Thanks in advance for any help.

I am having the same shifting issue and would like the manual as well to pull it apart to clean it. I need the 2000 Honda Foreman 450 manual. Were you able to find a link for it?

Thanks
Brad
