My bike is a 06 ZZR600 and I would like to change my front and rear sprockets to get more power in acceleration (sorry for my bad english, I'm a french canadian..!). I was only wondering how many teeth should I add to the rear sprocket (+1 or +2) considering I will go for a -1 tooth on the front sprocket. I also want to add a ''jet kit'' and I will probably go for a stage 1 ''Dynojet'' kit and a K&N air filter. Please give me your feed back about these modifications and let me know if it's a good choice!?
