2002 Honda 300ex Repair Manual

I would say you have a problem in your ignition system, something is failing when it starts to get hot. Most likely culprit is the CDI, but I would find the specs and procedures for the direct resistance tests and check everything else after you get it warmed up and it stops running. If you don't have a repair manual, get one, it will have the specs and procedures for the ignition tests and a troubleshooting guide to help you track down the problem. The Clymer manual is cheaper and decent, but the Honda factory manual is better IMO and worth the extra money if you ask me. So you are saying that if you let it warm at an idle for 30 minutes, it's ok?

Does that mean you can ride it without issue if you let it warm up that long? Or are you saying that it doesn't exhibit the problem if all you do is let it idle? Ride the machine until it shuts off, pull the plug out, and with it connected to the boot and grounded to the outside of the motor, turn the machine over and check for spark. This will tell you if the problem is related to an ignition issue or if it is something else.

I would still think the ignition is the most likely problem. I will say this again, ride it until it shuts down, take the plug out, ground it against the motor and turn the bike over to check for spark. If there is no spark, obviously you have an ignition problem, if that is the case, I would still say that the CDI is the most likely culprit.

Again, there are some tests you can do to check the other components. I posted some links for repair manuals in a previous post, on top of having test specs and procedures for your ignition components, they will have a troubleshooting guide that may help you track down the problem. If there is still spark after the machine stops running, then your problem is probably and interruprion in the fuel flow. That could mean debris in the fuel tank or carb, a stuck float or a fuel tank that is not ventilating properly.

I own a 2002 Can-Am Quest 650. It will start if you massage the throttle a bit and it will continue to run. BUT if you let go of the throttle and try to let it idle it will always die warm or cold. It has Non-Oxy premium gas, a new gapped NGK plug, a new carb (as of today) and fresh fluids. After installing the new carb it runs exactly the same. I only have a few things that I have observed since the new carb: The choke still doesn't do anything.

It has a good cable and it is hooked up. It on fully off. There is a cable in the top, front of the engine that splits into two connectors. The connected side is in the photo. The other side has the yellow banded section and is not connected. I do not see anything in range of this connector so I don't know if this is normal or not???

The original carb wasn't really dirty or clogged. I'll use it as a spare. I don't see this cable and connectors listed in the Can-Am shop manual. Looking for some help. I want to ride! 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.
