Yamaha Rhino Upgrade

Cam Installation

Information:

Web Cams has created a few different cam profiles for the Yamaha Rhino 660.  All of the cams take into consideration the weight of the Rhino. All of their camshafts are precision ground, heat treated and then coated.

I decided to go with part #80-411 Grind 461/496 Stage One, overall general performance.

Installation performed at Hart's Rhino Motorsports. Thanks to Paul for letting me look over his shoulder while he worked on my Rhino.
