I replaced the light switch on my burn e3 max, go figure out why i have to take absolutely everything out the handlebar, the grip, the nfc module the brake i mean everything

And then when trying to put this fucking throttle back i forgot how it was assembled, i tried every single combination of the square nut between the clamp, below or above, it doesn't clamp into the dent at all, and when i screw it with the final screw it doesn't seel to latch onto the handlebar, the throttle is still loose

I am absolutely not mechanically inclined as you can see but i really can't believe this shit, having to take everything off, multi part throttle, and all that because Mr Sha had the brilliant idea to be a fucking hipster with a concept, you know they love to do things a bit different thats their saying, regular throttles i had that are all plug and play on my Teverun or Dualtron aren't with Nami

And to add to all that, his official fb help group won't accept a new publication without admin approval, which takes between 2 to 4 fucking days so pointless to go there

I know i rubbed quite a few Nami fanboys in the wrong way, and that my useless hands are not helping the situation, but i swear to god this is the worst scooter i ever bought in my life , everything about it is a fucking pain in the ass, if anyone is kind enough to help me the minute i assemble it back i am putting it to sell

How to tighten Nami throttle on handlebar ?
