I made this restrictor for my daughters stomp ss120R pitbike,
it may or may not fit other pitbikes.

I ACCEPT NO RESPONSIBILITY IF YOU CHOOSE TO MAKE AND FIT THIS TO YOUR OWN OR SOMEONE ELSES BIKE!
IF YOU ACCEPT TO USE IT THEN MAKE SURE THE THROTTLE WORKS SMOOTHLY, DOESNT BIND AND THE RESTRICTOR WILL NOT CATCH ON ANYTHING!

you will need three m6 x 45mm long bolts (button head)

I used m6 metal inserts (helicoil type) to make the threaded holes more resistant to stripping, makes a big difference.

DO NOT OVERTIGHTEN THESE CLAMPING BOLTS AS IT MAY CAUSE THE THROTTLE TO STICK OPEN!
it only needs to be done up enough to stop it slipping on the grip.

i made it with 80% infill so its strong,
Try not to use support for the holes (its a bitch to remove!)

the restrictor in the pic is the version 1, the files are for the version 2 which has alot of improvements including a modified clamp design to make fitting and removing easier,
also a removable restrictor section for simple derestrction with just an allen key for when the adults get bored and want a go! lol

thanks
