F4 vs. F4i chain length
Hey All,
I've got an 2002 F4i that I wanted to do the 520 chain conversion to, and I bought a new RK/VORTEX on Ebay for $75, which is about half of retail. Only thing is it's for an F4 which I know uses a 45 tooth rear sprocket instead of the 46 tooth of the F4i, the front is 15 which is -1, so that should give me a little more oomph. What I want to know is are the chain lengths the same? I believe the frame and swingarm is identical on both. Every chart I see says the F4 uses a 120 link chain and the F4i a 108.
