Hey everyone,

Im not sure if its a insert that goes into the swing arm for the bolts of the chain slide but I had mine fall out. Just wondering if anyone has ever replaced that or knows what size insert to press into the swing arm.Below is a picture of the bolt im talking about.

After all my years of riding and racing....I had this exact same thing happen to my new 2018 YZ450F. Odd and puzzling scenario! Unfortunately, it’s just a 5mm bolt that holds on to about three threads of the aluminum swing arm. I first attempted to just clean the threads up and replace with OEM slider with some blue loctite. After a couple of motos I heard the chain slap and realized that the bolt was once again gone. This led me to tapping to a 6mm again using a OEM bolt from front fork guard where yet again the same thing happened. Now, on chain slider two and frustration of mid to end day moto bike failures I chose to get more aggressive. I installed an aluminum nut setter which is similar to a pop rivet. I installed this nut setter and used a collared aluminum bolt with loctite applied again. I’ve now ridden several motos with success and per my identification markings on the bolt/slider hasn’t budged. Looks factory and will be simple to change chain slider if/when needs replaced or upgraded. ??
