Im not sure who this might have affected but I own a 2013 500EXC and I initially installed the EXP 3.0 and a month later I upgraded to the Core Exp 3.0. While performing the upgrade the instructions have you reuse the steel lining plate which sits directly under the pressure plate. So if this sounds familiar you might wanna inspect your lining plate and pressure plate for any damage. My lining plate has tangs that are about half the size of the slots on the pressure plate that they sit in. Its a very sloppy fit and it had me thinking something wasnt right at first but I just followed the directions and put it in. After 1.5 months of riding on and offroad I decided to inspect the components and I found my tangs on the lining plate bent and grooves forming on the pressure plate slots. I called Rekluse on Monday and explained everything to them and sent them pictures and about 3 hours later they emailed me and asked for my shipping address and that they were gonna send me the correct lining plate along with a replacement pressure plate. If you look on their website and watch the Core EXP 3.0 install video for DDS style clutches and fast forward to the lining plate install part you will see a different lining plate, one with tangs that perfectly mesh into the pressure plate slots. I asked the Rekluse Rep if this was a problem arising because I don't think I could be the only one, but he said he never heard of this problem. But he did say as of June changes were made to the kits and I just so happened to have installed mine at the end of May. So Im guessing R&D thought they could get away with people reusing the lining plate but IDK. Well Im not here to bash Rekluse because the product is amazing and the customer service and tech support are top notch!!! Just wanted to share some info.
