Wanted to introduce myself .... I know some of you already from the Rhino world. I'm James Davis of JBS Performance in Mount Hope, WV. I made a clutch sheave for the Yamaha Rhino & Grizzly which is called the Hot Rod sheave. Luke Rogers & Mike Hinckley both run my sheave in their race bikes & we also did the port work on Luke's race bike. I myself have a 2009 Yamaha Rhino 787 with about 8000 miles on it. I love to ride & love the sport. If you have any questions about my product give me a call ... 304-673-2602 or email me at firstname.lastname@example.org ... thanks!
