I just want to know has any one replaced thier f4i's sprockets and chain with a 520 conversion kit. Pretty much how many teeth did you go up or down in both sprockets. and what company should i buy. thanks.

 

Sprocket size depends on what type of riding you are doing. One down in front (15) is working well for me. Drops top end by a small amount but gives much better low end. Easier to do wheelies in second gear. Vortex makes really good sprockets and RK or DID both make good o-ring chains. RK has a good deal on a kit with both sprockets and chain, and can be found on E-Bay or your local shop. It is a good investment for the performance gain in my opinion.

 

Whats a 520 conversion kit and the advantage??

 

Its lighter by acouple pounds.Thats it

 

What are an F4i's stock sprockets? i was thinking of dropping about 2 teeth in front for a better 0-60, good idea?

 

You can only drop 1 in the front but can go up in the rear.

 

I have a new on in the pasrts trader section if anyone is intereted, it is down 1 in the rear vortex sprockets and RK x ring

 

Im probably going to pick one up from e-bay, they said that they recomend two teeth up in the rear and one down in the front. Plus they are only$150 shipped for the chain/sprockets set. Anyone ever try this setup before?
