Mat,your vid isn,t very clear,can you rev the scoot on its stand,by skipping do you mean missing at the plug?

it doesnt happen on the stand its doesnt seems to be skipping from the plug when on stand it revs perfect when off it moves the whole engine up and down pretty violebtly but everything is connectd motor moving etc it never did this before until 2 days ago now its just like repeats at the same rev like 4,000 rpm skip 4,000 rpm skip 4,000 rpm skip and so on kts not all the time but it happens often sometimes when just getting to about 10mph sometimes it does it at 40 mph if it hbelps i noticed one time if backfired and it never did that but hasnt backfired again still skipping the 13 second mark in video is the skip im talking about please help solve thank you

Have you tried another spark plug ? Could of course be your cdi also.

I watched your video. Have you changed your plug after fully tuning the engine? It could be fouled. What plug are you using?

im using BP7hs stock plug ill get a new one If you're running a 70cc kit I would recommend a colder plug. Get a 8 instead of the 7 you're using now. |

Just curious have you checked your engine to frame ground starp? My son's came lose on his quad and it had a bad miss to it also it was very unpredictable.

Sooo hard to tell from that video...But seems like an ignition issue. I would prefer to say...retrace your steps. Something you touched, if good before, has changed.

Are you using the stock coil? I can tell you now, an upgraded coil from Naraku will compliment your 70 kit very well. I’ve tried both a new stock CPI (1e40qmb) and one of Narakus hot orange colored coils, noticeable difference.
I’m with rune75 also. I use an 8 plug, it stays decently cool without too much carbon buildup.
