I've read a few posts on here regarding chains and sprockets, but I wanted to see if anyone could help me out with my 2001 F4i. I would like more low end acceleration. I would like to be able to bring the front end a little easier, but I dont want it to come up and the blink of an eye if you know what i mean. My buddy suggested the 525 chain (stock), go one tooth down in the front and two up in the rear (vortex of course). Any input on this combo from some seasoned veterans would be appreciated. thanks guys.
