I was looking at http://www.dubachracing.com/cart/index.php?main_page=product_info&cPath=4&products_id=29 and was wondering if anyone has any first hand experience with it. The bike is an 02 YZ426 and I consider myself a strong novice and possibly intermediate rider. I mainly ride motorcross and would like to start racing but haven't yet... I know I would need to change the oil more often but I am thinking that since there will be no oil in the frame oil changes will be faster and easier and that since the bike will take less oil, the more frequent oil changes won't cost any extra $$. I like the idea as the bike will look ever-so slightly cleaner and that oil changes will be easier but I don't want to negetively affect the long term health of the bike.
