Re: NEW CHAIN AND SPROCKETS
i did the 520 conv. at 8,000 miles, -1 on the front and love the acceleration, definitly worth the slight loss in top end. as for vortex sprockets, i ran that set to 25,000 miles, or 17,000 miles total. just changed to a new set, -1/+1, and the wear on the sprockets was due to the chain stretch. i'm not saying they are the best, but i have no problem with them. as for the miles i got out of the chain, i personally will always run an RK GB520GXW. it has the highest tensile strength of all the top of the line chains, but i'm basing it off my personal experience.
