1. Defective product
I bought some LightTech chain adjusters for my 2015 Yamaha FZ-09 and I tightened them to 73 lb-fts per the instructions provided with the adjusters. The problem comes in that I installed these in October 2021 and did not need to do any chain adjustments or tire changes till August of 2023. When the shop that i have used for years tried to remove the rear axle the guides broke due to very soft aluminum and the axel just spun. I reached out to Barry Chatham to try and get these replaced under “good will coverage” and that was denied. I would not recommend this product due to how weak they are and the fact that the company does not seem to really warranty the product. Below are the pictures of the adjusters after the shop cut the axle nut off and removed the axle and the adjusters.
