    2006 Yamaha WR 450f Performance Mods?

    I installed the AIS removal kit. It would seem that there would be more vacuum now that these ports are plugged. Does this affect the intake signal in the carb? Do I still use the same jets in the JD guide, or do some jets change. Am I overanalyzing this? How can I get the INDY's jetting guide. Is it the same thing as the JD guide?
