Don’t know what the specs are, but I’d think that would be sufficient. You have stated that you have idle issues, if it was a low fuel pressure problem I’d think your problem would be even worse when riding the bike under load. I noticed you haven’t stated if the bike runs well off idle.When i start the bike cold the fuel pressure at idle is 43 psi but after i rev the bike and gets hot is settles at aprox. 47 psi, at idle, is this normal?
