If the starter motor is turning the bike engine over at a good speed, check for spark. Remove the spark plug from the cylinder. Re-attach it to the wire. Hold the plug with insulated pliers against bare metal on the engine. Get your pal to crank the bike. You should see big fat blue sparks. If you don't, you have an ignition problem.

If you're getting good spark and it's still not starting, try either the starter fluid as mentioned, or squirting gas into the cylinder (through the spark-plug hole). If the bike fires or runs momentarily, then you have a fuel issue. That could anything from: you didn't turn the valve on the tank on to plugged jets.

Good post but THAT is not a good thing to suggest to someone that you really don't know.......as it is real easy to put TOO MUCH in and cause an even bigger problem.

Ether (starting fluid), gas and carb cleaner can be introduced into the air box for safest results. Ether with the filter in place; liquids without it.

if you got a bright spark then a new battery wont matter. If you loosen a screw or two on your float bowl of the carb does gas pour out? If not it time to take the carb apart again.

How old is this bike? 400E's haven't been made for a while. It is entirely possible that the valves tightened up, and require adjusting.

Have you run a compression check?

SIGH!

If you do everything that everybody you talk to suggests, you will end up wasting a LOT of time and money.

Coils going bad on 3 year old bikes is rare; if it is showing a hot white or blue spark, then it's almost impossible for the coil to be the problem.

Have you considered letting a shop fix it ?? It might be cheaper in the long run.

P.S. If you haven't changed the plug(s) yet, you should. They can short out in a fashion that gives a false test unless you are REAL careful about how you do it.

Check the compression.
