WOW ..... Yes they do make them for me. I actually designed these kits. If you buy this kit from them they are $99.00 each PLUS shipping. I have ordered alot of kits from them and have had no problems? I am sure if you call john and told him your problem he would make it right. Installation is key.....not too much water, let them dry, no heatgun or blow dryer, remove all excess water, ect. I have not put them on a YFZ, but i have put them on these bikes TRX450R, TRX250R, and LTZ400. All of these kits were put on about a year ago and no problems yet, and the fit was better then most.
