Translate "injector bleed down," if you don't mind. Pressure is being lost through the injectors themselves?

Just fixed up my manometer ... hope to do TBS in the next couple of days - can't hurt.

It could be that's how some of mine act when they've sat for a bit but I don't let them crank that much. I stop after after 6 rotations if it doesn't start, wait a few seconds, give it another shot and it fires up.

Fuel system runs at about 3 bar. When you shut off the engine it should stay moderately pressurised so it's ready to go next time you start it after the short 2 or 3 sec fuel prime that occurs when you switch on the ignition. If there is no pressure left it takes 2 or 3x primes to build up pressure again. Can be a minute leak at the regulator or in the fuel lines around the rail but mostly the injectors are just not shutting off properly like a dripping tap.

Hmm, interesting. It's the first I've heard of this. The bike starts fine after this initial go-round, but the next day it'll be the same delay routine.
Does this mean that the injectors need replacing? The vacuum hoses are new. Curious.

Hey chickenstrip,

Have you been using ethanol fuel? I know on my Husaberg, the injector will get a bit of some precipitate kinda like water scale that collects on the nozzles if I run regular pump gas. Ethanol free gas and a regular injector cleaning fuel additive may help.

You can have the injectors rebuilt at any reputable injector specialist. They can be beyond repair though.

$185 new! And from the looks of it unobtainium, according to Bikebandit.
Maybe there's a there's a non OEM equivalent?

What? Ethanol fuel? I've never heard of such a thing! 🤣 It's pretty hard, maybe impossible, to find non-ethanol gas around here.

Well, I hope it's not the injectors. Next step is TBS and new fuel filter.

I vote you get them cleaned by a shop TBH, injectors aren't crazy specific to a certain bike. If they're FUBAR, and I highly doubt it since they behave otherwise, chances are your local parts store can source them.
