Great product at a bargain price. We added about an ounce to my 99 buddy's softtail before our trip and he had to lower his idle speed! During an oil change and subsequent city trip, Militec came along. I pulled up to the light and you could hear it turning much faster. I did the same thing on my Triumph Tiger Explorer - almost no engine stall when downshifting. This is a large and obvious reduction in friction. I added lube after the first oil change - I would recommend waiting until the new engine is broken in to add it. Pistols, rifles, engines. Please note that metals must be heated to operating temperature for recording. This is a great thing and the company is made up of good people looking after our troops. Shipped and delivered on time by USPS by Militec.
