Lots of possible reasons for that, why do you suspect spark plug? What are your symptoms? Cranks, tries to fire but doesn't catch? Cranks but doesn't even try to fire? Tell the folks more, dude.

Hello, then my scooter has been parked two months with the battery pack being charged, when I tried to turn left almost immediately, but then after about 30 seconds it was off by itself, when I try to turn the starter motor turns and the battery is good but will not start. It could be the spark plug dirty or replace?
Thanks
Bye

Yes it could but more than likely since it's been sitting it's other things. Pull the spark plug, inspect it, then place it on a good ground source and turn the engine over to see if you have a good spark, one process at a time to find out what's going on.

what kind of wrench to unscrew the spark that measures need? thanks goodbye On my 2011 Roketa, which I think is pretty much a clone of your scooter, I have an NGK DPR7EA, and it takes an 18mm socket to remove it. (My scooter has the vertical, 244cc, Honda-clone engine; not sure if the horizontal, 257cc, Linhai engine has the same plug.) |

As to the next part, are you saying you put the plug back in its rubber boot, cranked the engine, and no spark at the electrode of the spark plug? If I understand that part correctly, it COULD be a bad plug, but they're pretty simple and reliable, and I'd check at least one step further before spending the money for a new plug. Take the rubber plug boot, WITH PLUG REMOVED, and find a way to ground it. When I do this I insert a nail or screw into the boot. Then crank the engine and hold that nail or screw CLOSE TO (not touching) a bare metal ground like the scooter frame or one of the bolts. What you want to see is a spark jumping from the nail to the grounding surface. If you don't, your problem is somewhere in the ignition circuitry. Working your way "upstream" from the spark plug, the possibilities I know of are -- loose or broken spark plug wire -- coil broken or has bad connections -- CDI broken or has bad connections -- Regulator (which is where the CDI gets its electricity) is broken or has bad connections. -- Stator (which is where the regulator gets its electricity) is broken or has bad connections. (Just wondering -- "candle"? I'm guessing maybe you're a German-speaker, as in "Zündkerze"?) |

Hello, thanks for reply, pardon my language but I'm Italian and I'm helping with the translator google, in italian language spark plug is said "candela".
It could be a problem while you switch to the side stand?
Thanks
