My son's motorcycle won't start!! (70cc pocket bike)?

It was hard to start, so I thought maybe it needed a new spark plug, so I took the old one out and went around town looking for a new plug. Nobody could find one that matched the old plug, so I looked online and ordered a plug from a pocket bike online dealer and put it in the pocket bike. It still was very hard to start, so I put the old plug back in and when I put the boot back on the plug, I guess I didn’t put it on all the way, so it was just sitting on top on the plug, but not pushed down all the way. It fired right up and it ran very well, even thought the boot wasn’t on the spark plug all the way. So he continued to ride it. Now when I went to start the bike for him this past weekend, I couldn’t get it started. The electric starter would not work. There is votage coming from the battery to the starting solenoid, but no voltage coming out. When you push the push button starter, nothing happens, no noise or anything. What might be wrong? Change the solenoid? Also......

First check any fuses. This may be why there is no power getting to the solenoid.





The spark plug boot problem sounds like the spark plug wire needs to be replaced. But it could be a coil problem as well.





Replace the fuse (if bad), recharge the battery, and see if it will crank with the electric starter.





If not, then check the wiring leading to the electric starter motor. Best test is to remove the starter motor and hook it directly to a battery. If it runs, then there is a problem somewhere in the wiring on the bike.





If the starter runs after fuse check and battery recharge, then check the spark plug cable first. If a new cable does not solve the problem, then check the wiring to the coil, then the coil itself.

Plus this whole pocket bike craze is just lame. You ask questions here, in a motorcycle forum about a toy!!!!


Go figure....
Reply:You might try to clean the spark plug with paint thinner. It may just not be gettin the fire it needs, due to dirt and gunk. That is the only thing I can think of, right now. Rock On!
Reply:Battery maybe low, charge it then see what happens. It isnt starting because not enough electricity is getting to the spark plug to create an adequate spark for ignition. Replace the battery and charge it fully if needed, if that doesnt work then check the cable that leads to the spark plug, it needs to be tight.





The only other thing is that you should turn the throttle very slightly to allow some fuel into the engine, that will help it switch on though too much will flood the engine.
Reply:You buy junk, you get junk. As a rider, I have no respect for those things. Buy a real bike. EDIT: In my area those types of "scooter" have been made illegal. Dangerous on the roads and difficult to spot by other vehicles. For your son's safety, don't get it fixed, even if you can find someone that will try to fix it.
Reply:Check manual on spec's for spark plug gap.


You may have a burned spark plug wire and it may be arking on the engine instead of gettin to the plug.


Silanoid could be burned out. Also check silanoid fuse. Make sure all connection's are clean.
