Review on American V Twin Primary Lubricant Ounce by John Kushmaul

I recently purchased a primary lubricant for my motorcycle and it has done wonders for my American V twin's performance .As a result of using this product i found that my gear changes were smoother and my engine ran quieter. The product is affordable and easy to use. The only downside is that I had to wait a few days for delivery as it is not available in stores. Overall, I highly recommend this product to all automotive enthusiasts..
