Still rattling

[0105]

Me again... I know your primal all suck off me by now but here goes another, I've sorted most of my issues out on the scoot no but I still have this awful rattle coming from the engine (99% sure) when I'm doing about 35mph in 4th and try to accelerate and when I'm holding it almost flat out in 4th, so it seems to only do it when the engine is under load.... Just want this bloody fixed so I can ride and enjoy it

"primal all suck off" , another great auto-correct howler i reckon .
an i'll swear mushrooms straight , like me, ive been in his shed bent over a scoot an no hint of "impropriety", could be coz i'm so dang ugly tho. but havin i think 6 kids by last count is a bit of a give away ,hard to count them as they dont stand still .
i think we need a video or sound recording to tell more ,but "rattle" under load could be detonation/pinking ,does it sound "pinking" . an have you gone round scoot checking for loose components ,exhaust mount/cdi bracket/etc . try a run without panels an what barrel is it , as ali ones with out the rubber spacers in between fins can can "ring" at certain revs .H

0105, does it sound like marbles rattling around in your cylinder head?

😂😂 "primal all suck" how the hell did my phone get that from "probably all sick" any way yes it does sounds like marbles (more like stones) rattling in a tin I think it is pinking to be honest, I changed the atomiser earlier from an E3 to a BE3 and went up to 116 main jet and the noise has almost gone but still very slightly there, I'm running a 150 5 port top end, chrome sip road 2, 20/20 carb, 38-120 idle, 160 air corrector, BE3 atomiser (was E3), 116 main jet (was 108) and..............wait for it...... The dreaded polini Venturi system 😂
