Default Sprockets! sprockerts and rockets!

Hey thanks for all the responds on my other posts, and it really helped me alot. I got the forkseals changed, and i adjusted the chain also, however there is alot of tight, and loose spots and its crazy, i got a 1.5 inch slack on the loose spot, however there is very little slack on the tight areas, i know when adjusting the chain i should start with the tight areas but if i start there, my chain will almost fall off!

Soo i found a hardly used chain that is in alot better shape than the one i have, and a ordered a 16t front sprocket, im currently running 46t in the back. Im wondering what the stock size is? and if it'll make a difference if i change it out to a 47t sprocket? Sense i dont know what a stock sprocket size is, im pretty sure my milage is WAY off! I should probably only have about 13000 miles in the bike, but it reads 30000 lol, its gonna be hard selling a 100,000 mile motorcycle! :/

Anyways to make this post simple, what's the stock sprocket size? and once i get this new chain my bike is good to go, and my OCD will me less of a worry ha! oh yeah, the bike is a 2001 f4i

ohh and a 47 would give you a little more torque/acceleration and loose from its top speed. and throw off your speedo.

Mine has a 48T on the back (not sure what the front is). It feels a lot touchier driving at low speeds around parking lots and stuff compared to my friend's F4i. That and I'm putting a lot of false miles on.

Very little. MY setup = 16/48 (+2 rear) and my speedo is off roughly 4%. This means that at an actual speed of 100mph, my speedo reads 104mph (i think).

At lower speeds such as 35mph, it reads roughly accurate. I paced with my friends 600rr at 35mph and mine said 35mph.

if you went 47 rear (+1) your speedo error wouldn't practically make enough of a difference to worry about.

Pretty sure my front sprocket is smaller. I was following a friend on the freeway right after I got it and my speedo was reading upper 80s. He said he was only doing around 75. Judging by the pace of traffic at various speeds, seems 16% is about right.
