Whats up everybody! I am looking to replace my chain and sprocket chain with a complete new set on my 02 F4i. It is dirty and has about 13,000 miles on the setand the chain definately needs to be replaced. Right now my bike has a Vortex -1/+2 with some brand of chain. (Im not quite sure) What would everyone reccomend as a good replacement? I want to stay with the -1/+2 to keep my bike torqueee so what do you guys think? Thanks alot!!
