New front sprocket
I've heard that if you change a sprocket you should change both and the chain at the same time. My front sprocket, 17 tooth, has quite sharp points but the rear is like new. The teeth are still squared on the tops. I checked the service limit of the chain and it is like new. I have 17k miles on it.
Do you pros think I can get away with just replacing the front sprocket and leave the rear and chain as is?

Im no pro ! but if the chain aint stretched and has been kept up then there's def no problem. The stock chain on the 12 is really tough for the HP that is put through it.

some of us put a lil bit more power thru the chain  (i have an ek zzz though)
if your chain and rear are fine, dont change them. get a new sprocket from a zx14 or zx11d

well then I guess it depends if you are like most and ride the street. If you drag race and pound the shit out of it well id say time for a new one.

Thank you gentlemen.
No drag style launches for me, and with 7 points on my license I've slowed WAY down. I think I'll just do the front sprocket for now.
