Modify OEM Fuel Pump For Increased Fuel Pressure – Yamaha R3

Description

When building an R3 Superbike, you may run into an issue where the you reach 100% duty cycle with the fuel injectors and OEM fuel pump and injectors cannot supply enough fuel to properly tune the engine.  This modification will increase fuel pressure to allow for higher flow and solve this issue.

*Changing fuel pressure will change your fuel mapping!  If you are building an R3 Superbike, we recommend this modification before you spend a bunch of time and money tuning the bike, so you don’t find out at the very end that you need it and have to start over!

*This is a modification to your OEM fuel pump.  You must send in your OEM fuel pump to be modified.
