Both of mine broke and I just welded a washer around the bolt hole after welding the cracks up. They have held up to hard mx racing just fine and I dont run a headstay. If you want to drop them in a padded envelope and mail them to me I will weld them for free and mail em back.
Also check your lower motor mount bolt under the motor. My front mounts broke because that lower mount bolt came loose.
my bottom ones broke too, i welded them without fixing the front ones thinking that would be good enough and they broke again as soon as i kick started it. im not a very good welder though. i was gunna weld all of them but i didnt have time and had to go riding in the morning. i dont run a headstay either.
so this time im gunna weld the bottom ones again and get new front ones and that should hold. i should be able to get some front ones for cheap, i know ive seen them go on ebay for like 10 bucks in the past but i didnt need them then. if i cant find any i will take you up on that generous offer, thats pretty cool of you. thanks
