Hello I have a 1996 CBR 600 F3 smokin joe edition, is was wondering what are the best jet size for more top end.

K&N air filter
full exhaust with mrv exhaust slip on

 

No way to know for sure. Every bike is different with different manufacturing tolerances off factory line. And different amounts of wear and tear over time. Need to get on dyno with exhaust analyser to see what your AFR is now. Then adjust for max-power AFR of 13.5:1
