PIM2 Unit (2010-2012 or 2013): Yoshimura introduces PIM2, the evolution of our original Dirt Bike/ATV fuel injection adjustment “PIM” device. PIM2 installs easily, typically in under 30-minutes using simple Plug-N-Play technology. Plug the PIM2 into the stock wiring harness, mount to your bike using the supplied mounting kit, and you are ready to race! The PIM comes pre-loaded with two separate fuel injection maps for either a Yoshimura Slip-On or Full Exhaust System. But the adjustability is limitless and easy. If those two maps are not enough - there are dozens of maps to download for FREE on our website. Maps available for Yoshimura Slip-On and Full Systems here.
