Salt Flash. A Bonneville Beezer.

I understand how you feel Briz, I was in the same boat a while back
This was my solution

The Mikuni floats, needle , seat and associated fuel level devices were replaced by the Holley, which will handle 5 PSI
You could work on a similar setup on your animals while the bike makes it's way to Bonneville ? , Just make sure you have the room for  Holley bowls.

Briz,
I've had good luck running S&S supers on my Kawasaki turbo drag bike. Also ran Rivera Engineering's modified 40mm Su carbs on the same motors, both with fuel pumps. Good luck.

Briz, sometimes it is the combination of vibration and pressure that causes the problem.  As an experiment, try mounting the carbs so they do not vibrate and see if the problem persists.

Tiny, that's a very clever mod. Go you good thing!!!!

Briz, I am not sure of the specific gravity of the fuel you are using.  In some cases the floats need to be dropped if the fuel is significantly lighter or there is a need to overcome pressure at the float valve.

One thing to try is to tap a clear hose into the bottom of the float bowl and to run it up alongside the carb.  The fuel level in the hose is the same as it is in the float bowl.  Try it with gasoline in the carb first to see where it should be.  Then, try it with the fuel and adjust the floats till they give the same height when the bike is running.  Remember, the deeper the float is pushed down into the fuel the more pressure it puts on the needle.

A T-valve in the feed line to he carb can be adjusted to shunt fuel back into the tank and this will reduce the fuel pressure at the float needle.

Thanks for all the advise guys. We do have a recirculating pressure regulator, and the problem exists without the engine running.
I really like that Holley float chamber idea, I'd like to try it sometime. No time now though.
Dave Branch came up with the simplest idea....switch the fuel pump off until we leave the line! The float chambers hold enough to idle a fair while and can be topped up by 'blipping' the pump.
So we rewired the kill switch to just kill the pump; we still have the lanyard to shut everything down.
It works...well enough anyway. We made a short run up a nearby driveway. I think we're going to bring it along & give it a shot.

That's the way to do it -- take it and try it.  And it's way fun and challenging to do work on a race vehicle at the salt.  If nothing else - there isn't a tool known to man that isn't available in someone's pit.  See you on the salt.

SSS...........I think Briz already owns more tools than most.............and certainly knows how to use them

[Seldom Seen Slim]

No doubt about his abilities, but if he's going to be zillions of miles from his home shop -- he'd likely want to borrow some since they can't all fit in the container.

[Briz]

Yeah; you aint kidding! Inevitably forget something crucial.
Fortunately, team-mate Shaun is the worlds best at finding & borrowing stuff! We call him 'chief blagger'

It's being packed up tomorrow ready to be loaded into the container on Wednesday...

I was glad to see the clutch/belt/drive(?) cover laying over by the station wagon.  Hope it ships, too.

[Briz]

LOL! yeah, Its on there now.
Bike is now in the hands of the shippers. See you all at the salt!

With months to spare.

You rock man.
