Great video - i just bought a scooter and just found why the bike cuts out sometimes / wasn't turning on. Opened up the scooter to get to the spark plug and saw it was hanging loose. Thanks for recognising and sharing this video.
Thanks. Cool. These small scooters bounce around a lot. Much more than an auto with shocks. Next time I change spark plugs, I will see how hard or easy to pull that boot off. If too easy, I now know how to fix it. $ saved.
First my vino kept dying at stop lights ...then hit a bump and wouldn't start at all...i.am no mechanic but I checked the basics...air..fuel..fire...spark plug cap looked on...but was not!..thanks for video making us aware!-!!!🛵😃
What kind of scooter was it? My brother has a 2012 Zuma 125 and swears he is missing that top screw on piece that usually comes on a typical plug. I know he’s wrong tho 🤣
Their is a piece that unscrews on the top of the plug exposing the threads you need them for that wire to grab onto. Some plugs have that thing screwed on its meant for a different type of boot. My bike was a sunny 150cc they are all pretty much universal the brand name doesn't really matter all same parts.
Hey Chris so I've put the little screw back on spark plug and it's secure but I had a little piece of lead and a spring fall out the spark plug cap. Do I just put them back in and then screw it into it
I made a way easier fix just chop off the boot and shim some wire out wrap it over the wire a hair and plug it on the plug works great been running mine like that for awhile now
Could be a loose connection or the pickup coil Is weak or the cdi is going out. How do you know the spark is low? I would start with a new plug and make sure you gap it to what the plate in the bike says below the glove box. Let us know what you find out.
@@FRANK87car never seen a scooter that can use that cap that's only in cars. As i show in the video there is a small piece of wire that grips the threads on the top of the plug if you put that cap or whatever its called on the plug it will not fit inside the boot and there are no threads for that wire to grab onto.
@@FRANK87car That must be a rare case because all scooters i've worked on have the small wire inside the boot that grips the threads on the top of the spark plug so that cap cant be used. These are chinese scooters all the same parts yours might be from a different country and there fore better made parts and different parts.
@@chriss4365 what would cause it to shut off on low idol I have to have the idol pretty high for it to stay running when i let off the gas. I cleaned the carb replaced the plug and Set the valves could it be the plug wire ?
@@chriss4365 he was probably stuck on the side of the road thinking his valve nuts vibrated loose or something, when it was really just his spark plug boot falling off. This video is one of the most useful scooter videos on RU-vid. Thank you
How will buying a poorly designed cap help? You have to modify them. None of them clamp on the plug hard enough. You have to adjust the clip so it will hold onto the plug.
@@chriss4365 I’ve been riding two strokes and four strokes for 30 years and had a loose cap once. I put a new one on as when they get loose the rubber housing is probably perished anyways. 😉
