Hi all
Anyone know about the fuel pressure regulator on the R3? When I had my 955 Sprint, I found a post on a forum about (thanks to whoever it was) .....the cheapest and most far ranging mod to up the fuel pressure from the stock regulator setting of 40 psi to 60 or more. (set at 3 bar on the R3, 42psi)
It doesn't change anything but provides for a bit more richer mix throughout the entire mapping range which is what Sprints apparently needed as they are mapped lean. He also believed that it provided a better spray pattern from the injectors.
This is easily done by modifying the existing fuel pressure regulator by squeezing the steel case a bit in a vice to increase the spring pre-load. I never got round to trying it before my Sprint was written off in a smash.
Just wondered if this could be done with a Rocket? I haven't been able to see the regulator well enough in the manual.
thanks
