Yamaha T-Max 500 04-11 Polini pressure regulator

Polini presents us with one of those TOP products to prepare at a high level the popular and powerful Yamaha T-Max 500 2004-2011.
This is a pressure regulator that allows you to increase the fuel pressure reaching the injectors.

The pressure goes from 2.5bar to 3.5bar. This regulator is almost essential for T-Max models with high-level modifications.

We are talking about ECUs, exhausts, oversized cylinders, camshafts, etc... These modifications affect the operation of the ECU and always require more fuel in the cylinder, which will need extra fuel pressure at the injectors.

With the standard pressure, and the engine modified, at high revs you may find that the cylinder demands more fuel. With this pressure regulator, when the cylinder demands fuel, the injector will have enough pressure to keep delivering fuel.
This is a TOP product, derived from their T-Max competition teams.
