DINLI 50 DiamondBack

[MudStud]

I just picked up a used Dinli 50 diamond back for my son. I NEED to get the throttle limiter screw as the people took it out as their kids are older, my 4 yr old NEED the limiter.. Can you tell me WHAT the exact tap and size is I need?? This would be AWSOME, I wont let him ride until I get it for him as he has NO clue about some throttle vs all throttle..

I just looked at my Jetmoto 250 and Yamoto 150...both use a M5X0.8 tap/screw..
