After reading and asking I am ready to buy the stuff i need for my carb. I want to run the list past everyone here first to make sure I am getting what I need, and not getting what I do not need. Don't have money to waste. If I have made a bad choice, or should be getting a different brand or style, please let me know. I have already purchased the GYTR AIS removal kit. On the list is: JD jet kit Merge Racing fuel screw Merge Racing accerlator pump spring Boysen AP cover And I am on the fence between the PMB instert or a slip on such as the FMF Q4? Which will help my bike perform better and jet easier? Not sure how necessary the ap spring and cover are or even what is involved when installing them?
