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

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......

Check for a small inline fuse from the hot side ( where battery lead hooks to starter solenoid ) that runs to the ign switch - 90% of the time when this blows out - you wont be able to start it. If it still wont start, then possibly the solenoid needs changing.


The spark plug- well it probably fired even tho the boot wasnt on right.


When was the oil changed last? That could cause hard starting .


Or does it use pre mix gas? Maybe its not mixed heavy enough.
Reply:Try the solenoid first. Check for spark by removing the sparkplug boot and spark plug and let it set against the motor to ground - crank motor- should see blue spark. Report It

Reply:Keep it simple. First off, the plug wire boot may have not fitted on correctly and the power could not get to the outer end of the spark plug thru the wire because it went deeper. Sometimes they are weird. Still try to fit it on so it is on as best as it can be and the bike stays running.


The starter thing. Is the bike in neutral(Know how to operate this thing - read the manual-) It could be like an automatic car, if not in N or P the starter will not engage.


So too, may be the case if the oil is too low. I don't know, read your book.


You just bought the darn thing. It should not be breaking down yet. Give it a couple of years. Just don't freak out. Sit down have a coffee and be leisurely about it (and rational and step by step methodical)
