ok guys i am brand new to the forums and i just got my first bike about 2 months ago and i am looking for some good mods...it has a 2 brother racing exhaust and i really want some new sprokets. what do yall think is the very best brand and size to go with front and back. also what else would help with performance?

 

I would recommend against getting vortex or cheap ebay knockoffs, just a personal preference. I've used AFAM before with good results. I'd also highly recommend replacing the chain while you're at it, so you don't cause any premature wear on the sprockets, get RK or DID for the chain.

 

dang i just got a brand new chain right when i got the bike...how many teeth you think would be best and all that

 

You *might* be able to use the same chain as long as you stay near the same amount of teeth, will just take some adjusting and some fenagaling of the new sprockets to get them on. If you change to 520 sprockets though youll definately need a new chain. Popular gearing is -1 in front and +2 in rear, which is 15 teeth and 47 teeth respectively.

 

make sure you know what your rear sprocket is stock b/c they vary among years, what do you want to do with your bike? is it gonna be mainly a rider or are you lookin to do some stuntin, probably -1 +2 would be good.

 

Well if he's posting here in the F4 forum, I would assume he has an F4. All 2 years of the F4 had the same sprockets: 16 front 45 rear.
