Look at getting a Dynojet kit, looks like you need a 'stage 1' kit:



STAGE 1: stock engine/filters, stock/modified exhaust. STAGE 1 kits increase power by about 5%
STAGE 2:stock/mild modified engine, stock/modified exhaust, stock/modified filters. STAGE 2 kits increase power by about 8%
STAGE 3: stock/mild modified engine, stock/modified exhaust, individual air filters. STAGE 3 kits increase power by about 10-15%
STAGE 7: Race ONLY, High RPM. NOT FOR STREET USE

Here is a good guide to jetting with testing as well as suggested jetting depending on the type of filter and exhaust fitted (ie if you have desnorkeled or have tank raisers etc) there is also the setting up of the needle clips and checking the float height etc so it not just jetting you need to think about.
