I have a slightly used Rpm cog Setup that I recently purchased from a friend. I thought I was going to run this on the stock eaton but I really want to do a big blower so I am in the market and should hopefully have a new blower this week. Anyway it is the Complete Moto Cog Gen 2 setup, It has a 4lb lower and I want to say an 2.8 upper with the kit. It has a brand new Cog belt as well. This setup sounds amazing!
