Do I Need A Fuel Presure Regulator With My Facet Fuel Pump For R1 Carb

[Guest windscreen man]

Ihi guys, do I need a fuel presure regulator if I am using a facet pump with r1 carbs, if so which one can I buy thanx

[Guest 2b cruising]

Not an absolute necessity. However they are advisable to stop any pressure surges and aid smooth running. You must also make sure of the correct pressure setting for your carbs as to much can start other problems. ie, leaking seal or gaskets, leakage through float valves ect.

Best way is to find what pressure the bike run at. Then set to the same as it does not matter what size of engine you are running. The pressure with carbs is only low in comparison to injection systems.

Run one of those with my twin 40's set at 3 psi, prevents excess pressure on needle valve in float chambers.

Facets come with a big range of pressures. Commonly about 4psi but up to 15 depending on model. Use a regulator if using bike carbs or better still use a bike pump.

I have the same one as cma linked ...set to 2.5 by rr..on my pinto with fireblade carbs

Just this weekend i found that my bike carbs are VERY pressure sensitive, i'm running a facet pump (using a filter king regulator with gauge). Even with new needle valves and seats in the carbs 3psi made fuel dribble out - and i had to back it off to 2ish - now runs handsomely.

Most bike carbs need approx 2.5psi, i certainly ran mine that way with no problems

R1 carbs on 2.1 using standard mechanical pinto fuel pump with regulator set to 1.5psi. No probs.

[Guest mower man]

Never bothered with a reg but mainly ran orig mech fuel pump, last off ran a Facet cube pump rated at 1.5 to3.5 psi no probs ,this was with a 38 dgas on a 2.1 [slightly warmed over [145bhp at flywheel ] bike carbs would prob be ok on this I think mowerman N.B. my ops only !!!!
