I have noticed that the front sprocket seems to be the only one being changed. Are larger sprockets available for the rear of the 700xx? It looks like there is not much clearance between the bottome of the sprocket/chain and the steel plate just under it. The one I am looking at has a 14 front and 37 rear. That's pretty tall. The 14/37 = 2.64 final drive and the 13/37 = 2.84. Maybe the tranny ratios make up for it. I run 12/44 =3.66 on my Raptor with 22"x 11"x 9" paddles in the sand and 20" x 11" x 9" Razors on the trails.
