I\'m not too good with new bikes, BUT something stupid you could check or try,



HAD a newer moped I was playing with for 2008, It had a Kill switch on the kickstand, so try with kickstand up to start the bike,?

check fuel filter and shut off in float chamber , if you have spark and gas , still not firing check timing .

Bad stick coil

You didn't say what type of bike you were having a problem with but it sounds like a classic case of "fuel percolation". When the engine is hot and you shut it down, the lack of air flowing by the carb allows the fuel in the float bowl to boil. This floods the engine and it won't start.

Now, to determine exactly what's going on, The next time it does it, have a spare set of spark plugs with you. Pull the spark plug wires off the plugs in the heads and put the spare set in the wires. Ground them good on the engine and press the start button. Watch for the plugs to fire. If you see spark, then you know your problem is fuel related. If not, it's ignition related. Then we can go from there.

Tell me what type of bike we're messing with here?

it seems odd that your coils would play up, usally the they just stop working. You talk of it bogging down? , i would suggest that to be a carby problem, especialy if the bike has sat around for a while. first try to just drain the carbys, as you can do this without removing them, should be a drain screw or plug on the bottom of the carby. Make sure your air filter is clean too!

Quite often I've found on older bikes the coil can become corroded.  I would begin by taking apart all the electrical connections between the battery, ground, the plugs themselves, the coil, and the generator, and giving them a good clean.  Most of the time I've found, that should eliminate your problem.  A good way to troubleshoot this is to jumpstart the bike.  If the bike will start (i.e. has spark) while jumped, but will not run when you disconnect the jumper cables, it is most likely a corrosion problem somewhere in your system.
Good luck with your bike!

Okay, let's have a look at it. Say Ahaaa.
The probable cause of the problem is not the spark. Get a fresh set of Stock NGK spark plugs, ground the plus to the engine, and check each cylinder for spark as the starter button is pressed for 3 seconds or so. I will wager that the spark is present.

The likely problem is the fresh gas was put into a very rusty gas tank. Bits of rust now inhabit your carb and are having fun plugging up the carb. Look at the gas valve. With a little luck there is a small bowl behind the valve. Remove it and tell me what you see in the bowl.

Hi,

Initially, pls check/verify:

• left ignition coil goes to #1 & #4 plugs while right ign coil supplies 2 & 3;
• presence of spark on each and all of the plugs;
• temporarily remove the air cleaner/filter box/assembly and cover each crb opening with the palm of your hand while cranking. presence of gas would be noted with fuel on your palm;
• engine flooded. remove, clean, dry/replace plugs.

Incidentally, if no spark on plugs, check connectors to CDI, or starting with the clutch lever pulled.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.
