Roketa 125cc wont start! spark plug is not giving off spark?

I am trying to get this pit bike started for the first time since winter. i have changed the fuel out and changed the spark plug. it sounds like it wants to turn but wont crank up. took out the spark plug and put it against the engine and you can not see a spark coming off. the hole for the spark plug still has compression and can feel it blowing ur finger out when trying to kick start it. any help would be greatly appreciated.... my son is dying to ride and i am at a loss. thanks for your help!!!!!

Check the lead and connections between the coil and the plugs, the battery and the coil. If all else fails check the battery charge.

SOURCE: 95 Honda CBR 900 rr will not start.

Definatly a good tune up would help, but it also sounds as if you may have a bad stator. I would check the voltage at the battery and see if it goes up and down when accelorating.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Clean the air filter. Install a new stock NGK spark plug.

Please rate this solution. Thanks!

SOURCE: My son's bike just wont start. All of the normal

Tabbycat 282 s comments are right on the money!!
The three systems for any engine to run are fuel,mechanical, & electrical so we need to narrow it down to 1. It seem like you got one of those faults that just dosn't want to show itself.
Try as he/she & I suggested with introducing some fuel to the cylinder.
If that dosn't work, try removing the plug,(remove the airfilter also) blow down the spark plug hole with compressed air,fit a new plug(a std & not a racing plug is ok for this),re-introduce some fuel & try again(with the airfilter still removed).If it still dosn't go do also as tabbycat says and check the ignition timing next.
This could be a bit tricky as it's not running.
Hmm let me see!!!
Try hooking up an induction timing light. The type that has a pickup that clips over the lead.If it has leads to connect to a battery(& your bike dosn't have a battery) just hook it up to any 12v battery.
Now with the plug removed and resting on the head to earth it give it a kick while aiming the timing light at the magneto(cover removed)Hopefully when you've removed the cover it you can find some timing marks this may help to verify that the ignition timimg is correct.If you have a flywheel(magneto) puller pop it off before trying the timing light. It may have sheared the flywheel woodriff key & if the shop didn't remove the magneto/flywheel how would they know wether it has sheared it.(which would put the timing out)
Try get all the info on the things they "changed" & let us know exactly what they did!!
get back to us if your still having trouble & we'll see if we can come up with some other suggestions.
Regards Andrew Porrelli
PS when you check it for spark, the spark should be a fat, sharp blue coloured spark and not lazy, intermittent &yellow
Sorry my suggestions are a bit all over the place but without knowing what the dealer "changed" or did its hard to eliminate anything at the moment!!!

I have a pit bike 125 its not starting wot so ever got good spark but still not start


If you have spark them it must be gas. eather no gas or to much gas. Put it on chock, be sure the shut off valve is in on position.Now crank it over a few times , if it wont fire. Check the plug , is it wet or dry .If its wet then it may be flooded and needs to dry out and air out the cylinder.Try starting when dry. If its dry try putting a 1/2 oz of gas into the spark plug hole. replace the plug and turn it over . This will get them to fire up. Good luck DFD
