Should I only change the main jet and pilot jet?

 

Because according to Hyosung’s technical data, I also need to change the main air jet, needle jet, and starter jet.

 

I wanted to raise the needle and install a sports air filter.

 

I also have a 95 and a 98 main jet; would that work as an upgrade, or does it have to be a 95 and a 97.5?

 

Thanks for your help, and I’ll let you know how it goes.
