I take it that the electric shift doesn't work either, does it do anything? Do you hear a noise or anything that indicates that the shift servo is trying to work? Doesn't the shop manual tell you how to read the codes? By shop manual, do you mean the owners manual or do you have an actual repair manual? You need a repair manual, the owners manual isn't good for much more than telling you what kind of oil to put in it. I have no idea what the flash codes mean, but if the machine won't even shift manually, I would guess that either your clutch is faulty, out of adjustment, or you have bent shift forks or some other damage to the gearshift mechanism. I would start at the clutch since it is easier to get to and it can be adjusted from what I understand. The shop manual should tell you how to do it. If that doesn't help you could remove the side cover and inspect the shift ratchet. If it is a bent shift fork, or shift drum problem, you would have to get inside the motor.

It's more than likely a thing called the ' shift angle sensor' I have replaced HUNDREDS of them over the years. Dealer part, not too expensive... screws into the back of the case above the swingarm. betcha a quarter that's it!:yes:

Would a sensor keep him from being able to shift the machine manually with the emergency wrench? Seems like the sensor would only affect the electric shift.

yes, actually it can, if the sensor fails during an electric shift. It jams the shift forks and shuts off the actuator motor. annoying as heck! I've seen it many times... recons too.

I see, that makes perfect sense. I have heard of people having chronic problems with these electric shift systems. Ironically, a friend of mine has an '04 Rancher 350 ES, and it has been horribly mistreated, however, the electric shift is the one thing that has always worked.

      I bought a Honda 250sx 1986 but the exhaust is broken. Apparently it's not possible to order a new one. I checked to order one on others compagny but there's noting.
      Do you know which exhaust it's possible to install. Is there a company who sold an exaust to fit on my 250sx.
      Sorry for my english
      Thank you

      Im working on a old 1987 honda 125 4 wheeler in the school shop. It will start by getting pulled by another 4 wheeler but wont start with the pull start or Electric Start. When you pull start it it tries to start but when you try the electric start it just turns over but doesnt even act like it wants to start. The spark plug is dry and it shoots fuel out of the back(air filter side) of the carb. Weve had the carb off twice and it is complety clean. What are some things we can try?

      Hello I am new hear. I just purchased a 1998 Big Bear. It was sitting for 3yrs in storage. The guy I bought it from got the carb cleaned and it runs good. I am having problems with the neutral light. When I shift into neutral the light does not come on. If I mess with the gear shifter, I can get it to come on so I can start it. I can still pull the hand brake and start it that way. I cant find the neutral safity switch on this machine. Any suggestions would be great.

      Hope someone can help with this one.
      We took our 1984 Honda TRX 200 to the shop and they had it for about 2 weeks before they finally called and said that they had cleaned the carb and changed the battery and that it had started up.
      We went and got it and when we got home it would not start so we called them, they said bring it back in, so we did. They called us the next day and said they changed the spark plug, and that it was running. We went and got it again and it ran when we drove it off the truck.
      We parked it for about an hour because we were going to get ready to go on a ride. Well, it wouldnt start again.
      So we called them and they said the last thing they could do was order a new CDI box and put that on. I decided to just buy it myself, so I didnt have to pay them labor again. We put the new one on today and its still not starting.
      Does anyone have any ideas on what we could check to see what in the world is going on with this thing?
      Please and Thank you
