2007 Honda 400ex - Electrical Problems

Recommended Posts

i have been having problems with my 400ex. the electric start used to work great and never had a problem but throughout the span of about a month it started to dwindle down each day and now it doesnt even work. i can roll start it and it runs great but if i turn on the lights it seems to have no power and bogs down when i hit the throttle. i just put a new battery in it today hoping it would fix the problem but it didnt change anything. i dont know where to go from there so hopefully someone knows more than i do and can help me fix my issue. any input will help. Thanks!

take the starter off and either take it to an atv dealer or napa type place and do a load test on it. you can hook the starter up direct to a battery and see if it spins, but under a load it might not have the berries. check for replacement brushes too ...

If you have the engine running and then press the starter button and hear the starter motor turning that would indicate to me the starter is probably bad because with the engine running the starter is not under a load. If this is the case when you try to use the starter and apply the load of turning the engine over a bad or dragging starter motor cant handle the actual load being applied to it and it would quickly drain your battery down. In most cases a dragging starter is an indication that either it has been overheated and or the bearings are worn out allowing the armature to drag inside the case and bad brushes can also cause the starter not to handle a load because the proper connections are not present. Hope This Helps!

      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?

      Ok, so got this thing, assembled, and even added acid/assembled the battery with a solid trickle charge and the battery is fine.
      As far as I can tell, I have checked all the fuses I can find, but I have ZERO power to anything. Even the console will not light up when turned to ON.
      Is there some sort of hidden parental/child disconnect or safety switch that I'm not aware of? ANY help would be appreciated.

      I'm having a problem getting a CDI unit that works. The parts list calls for a  4XE-85540-00-00 CDI unit. The one currently on the ATV works but there seems to be a problem with the spark advance curve. It will idle fine an rev. to about 1.5K then  starts bogging down sputtering, popping and basically running poorly. If you can get it above 2200 RPM it runs better. I have ordered and returned about 5 replacement modules that will not work at all. The unit currently on the bike has no part numbers or identification other than a Mitisibuchi logo. I am wondering if anyone else has experienced similar problems with replacement CDI's and if so what is the fix? So far I have not found a replacement CDI that will supply an pulse to the Ignition coil.

      Hello i have a linhai 300 of the 2004+- era. I had a cluch problem so we changed it. After changing it has a hard time to start going. When you pop it into gear and press the gas it barely drives but when it starts going about 20km/h it start driving well the acceleration is normal and everything do you have any idea of what could be the problem

      I have a 2001 Quadmaster. Bought it from the original Owner. Its in Excellent condition for a 2001. The guy said there was a carb problem when I bought it. It seems like it is not getting fuel. I took off the tank, cleaned it, replaced the gas with fresh Gas, Installed a New Gas Valve. Then rebuilt the carb with a Carb Kit. Started it up and same damn thing, seems like its starving for gas. It will also backfire out the exhaust while trying to accelerate. Now the weird part. I started it the other day and it ran great. We went for a ride and it ran as if nothing was wrong with it. Started it the next day and back to running crappy again. I was like WTF !!! ... Anyone have any ideas of what the problem could be?
