True...true....the bottom to mid WAS not much on my 03 Auto Vinson....then I put my 27" Mudlites on...made it way worse. Yesterday I put the COMPLETE EPI Clutch Kit on my Vinson...the bottom-mid is super now....will be running it against my buddy's 650 this weekend....I'd be happy just to hang with him for a little bit. My machine is a COMPLETELY DIFFERENT ANIMAL NOW....But I'm sure the 650 has way more torque...that's a given being a larger motor. Before...I GPS my vinson with stock tires at 62. I will GPS it this weekend if I get the chance.
