Welcome to the family! I am by no means an expert but here are some things to get you started until an expert gets here. LOL

First is the battery charged? Does your neutral light come on? I doubt its the coil if it runs, Stator..not sure but I wouldn't think so. STARTER maybe, but first of all throw the battery on a charger and make sure its got full charge. After you know the battery is in good shape try jumping the solenoid (probably next to the battery, if it starts like that you may have problems in the switch or neutral safety switch.

EDIT - What happens when you TRY to start it? Nothing? does it click or buzz at all?

first off..if it will start if you push start it..it's not your coil..c.d.i, stator..you can rule those out...your problem lies in either the starter..or your starter relay, you can test this < make sure your battery is fully charged >..take an old screw driver..and find the starter relay...should be near or not far from the battery...jump across the terminals..if the bike cranks..then it's the relay...if it doesn't..then it's your starter...you can also take some jumper cables..hook them up to the battery < or a good battery..like your car or what not >..put the hot lead on the starter terminal..touch the neg lead to anywhere on the bike for a good ground..if the starter cranks the engine..then your starter is good..and the problem is your relay for sure..most times it's always the starter relay that goes out, check all of this like i mentioned..oh..you also could had a bad connection in the starter button switch..but..save this check for last..no sinse in taking the switch apart unless the other things check out ok first !. good luck !

I had a similar problem a few weeks ago. Mine was solved with a new spark plug.

I had gotten water in my gas, drained it, and it still wouldn't fire when kicked, I had my wife tow me behind my truck and finally got it fired up, and it would die when idling, but run fine as long as I gave it gas. And could not restart without a tow.

Side note: My local Honda shop raped me for 20 bucks on a new plug, I hate spending money there.

I've seen the stator get weak before and they wouldn't start off of the starter and you would have to push them off, but the starter would crank over.

Agree with all ^^^^^^Check your grounds and connections on the starter, bettery, and solenoid, you mave have a loose wire. also the buttons have been an issue in the past as well the spring inside gest week and won't allow the terminals to make good contact. If you have a charged battery and it only clicks at the starter relay and you can jump the starter with a screwdriver i would say your starter solenoid (relay) is no good.

all good tips. deff. cut the systems in half. make sure ur starter cranks. bye jumping as said ^. if it deos check ur relay. and make sure u have a good battery....... i love my kick start.. less wires and weight!!!!

good luck we are waiting to hear ur outcome...

Will the starter spin the motor at all? after it gets running and warmed up will it start with the starter? if it does i would check the valves, when they wear they don't want to start. I would check the valves anyway.

Will it run if you push start it? If so I dont think its your coil, ect, ect. Have you checked all your connections?
i have checked all connections,changed the coil,it won't start with the starter,only if you push start it,please help!!!

My guess would be a bad stator. I've seen them do that before, but usually when they warm up, they will start with the starter. Will yours start with the starter after you push it off and start it and warm it up?

if the bike will start when you push start it..then it sounds like the starter isn't either turning the motor over fast enough..or its not turning it over period..even though you hear the starter cranking...does not mean it's turning the motor over..check to make sure your starter transfer gears aren't striped out..and if they aren't..then that tells me your one way flywheel bearing is bad...you will need to take the starter transfer cover off..take one of the small starter transfer gears off..and try to turn the gear that is closest to the flywheel..it should turn freely one way..but lock up when you try to turn it the other way..if it doesn't lock up..this means your flywheel bearing < this is known as a sprag bearing > is bad...the starter will crank over..but it wont transfer the cranking to the flywheel...to turn the motor over...if you can push start the bike..then everything is working like it should..your problem lies with the flyweel bearing....i can almost bet on it .

I've seen the stator go bad and do that. You have to push start them to get them going fast before they will start. Then, after they warm up, they will start off the starter. That might not be the problem, but I've seen them do that before.

it could happen..but..from my years of working on bikes..on all the ones i've worked on..99.99 percent of them..if the stator goes out..or even bad for that matter..it won't run period...i've never seen a stator that works half the time..but..keep in mind..i'm sure it could happen..it's just that i've never seen it..a stator will either work..or it won't..i do know a stator has 2 sides of power..one creates ac voltage..sends it to the rectifier..and that converts it to dc voltage..charges the battery..and at the same time..runs the lights and so forth...while the other side of the stator..creates voltage..then the pick up coil detects it..sends this to the c.d.i..the c.d.i detects the piston is on TDC..then sends voltage to the coil..coil to spark plug..bam..motor runs..soo..my theroy here is..if the bike will crank when it is push started..then the stator is working...a good way to check this..pull the spark plug...hold your finger over the spark plug hole..while doing this..push the start button..are you getting compression ?..if your not..this tells me your starter isn't cranking the engine over..even though the starter is working..which.........leads me to believe the one way flywheel bearing is bad..now..i could be wrong here..and have known to be a few times..but..this is my theroy..lol.

why would the stator have a effect on starting? the stator is for electrical, running lights, charging battery,etc. i am leaning toward shadetree on this one. it has to be between the starter and flywheel given the fact that the starter is doing its job to begin with.
