Motopower Video Productions is looking for a YZ450F to use in a valve adjustment video. If you're willing to drop your bike off and pick it up when it's complete, our certified mechanic will adjust the valves for FREE. Valve adjustments run around $65 at a shop. Please email me if you are interested. I will contact you to make arrangement. We are located in Gilbert, Arizona. We already have maintenance DVD's available for the forks and have a bike lined up for the shock video. If there are other maintenance procedures that you would like to see please let me know and we may be able to use your bike.
