xj 81 550 only starts when Push Starting

i have a problem with starting the bike i have to push start it to get it going then after that, it starts fine but if i wait to long before starting i have to push start it again i have put new spark plugs cleaned all contacts charged battery fully tested solenoid (gooD) was wondering if it could be my coils i heard that these get hairline fractures in them and condensation gets in them preventing the bike from starting is this true please any help would do thank you

 

How new is the battery. It could be that you are not getting enough voltage out of the battery to effectively start it. If you have not checked the voltage output on the battery start there. Also if you have not done it check the fluid levels in the battery. If they are low this will also cause this problem. This might not be your problem but it is at least something to check. Good luck!

 

thank you for your response yes battery is newly purchased could it be what i suspect the coils?

 

Sounds more like a battery / starter issue if it fires right up by pushing.

Get a set of jumper leads and attach a battery tender and try to start. If it fires straight up then you KNOW it's a battery issue. If not, then check the voltage to the coils (you might need to do a relay mod if the voltage is low)

 

How many miles on the bike? It sounds to me like it's not charging the battery and riding it is running it down. Does it EVER spin from the starter button? Or go "click? Or??? Could be a lot of things; you haven't given us enough to go on...
