03 yz125

they actually make a plastic welder, u can get one at a harbor freight store for 40 bucks. the one i have is a hot air welder,just make sure u use the same type plastic rod as your 125 plastic. its kinda tricky at first and u need to find some (donor) plastic to try it out on first because u can ruin plastic quick. mine held good for ahwile but eventually cracked again
