I installed the tensioner yesterday. It took about 2 hours. You certainly need to be handy and have an assortment of tools. I took a 50 mile ride at all speeds and the vibration is totally gone. Now its such a pleasure to ride. I would recommend this product strongly to anyone that has an issue with vibration from the belt. I will never understand how BPR doesn't have one on from the factory. I pay $29,000 for a product that vibrates and they dont really care! Thank you Spyderpops for the great product.
