I am going to be away from my bike(02 F4i) for about 8 months. I decided when I get back that I will give it some performance mods as a treat. I am thinking so far to add the following, FMF Slip-on, Power Commander, K&N Air filter, and go down 1 on the rear sprocket and new chain. After all are added I will get it dyno tuned. Is there any reccomendations that you all have that could help improve my bike? Also I am from the south and never had to winterize a bike before, but now I live in the northern teir. What should I do to help it through the winter?
