2002 Honda 400EX keeps stalling?

5 posts in this topic

I have a 2002 400EX and took it out for the first time in months last weekend. It did ok in the beginning, but it would stall if I let off the gas. Then after riding for about an hour it would stall when I would accelerate. I am a newbie and have no idea what is wrong. It is all stock except for a K&N filter. Do I need to rejet it? Desert season is fast approaching so I need to get it fixed ASAP.

Yes, you need to rejet but the gas that has been sitting in your tank may have gone bad. Start with new gas.

      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?
