I dunno hoot about the way the bike works, but all my cars had the highest intake manifold vacuum at idle. Vacuum drops as the carb opens. Maybe the bike is different,

No,.. it's same... but, if the higher gear drops you out of the torqueband, you will have to open the throttle to try to gain speed... and opening the throttle will drop the vacuum...
...(same as if you go 30mph in 5th gear, and wick open the throttle... it'll chuf and stumble, and maybe die... vacuum drops to nuttin' and can't pull fuel.)...

That's my theory, an' I'm stickin' to it...
...'till Dave or Versy tell me I'm a dope... Grin

...

Mmkay, you're one of the carb gurus, not me. The stuff I know, I'll plant my feet and hold my ground
I don't have the expertise on the carb. I thought you could twist on the handle and until the vacuum raised the slide, the vacuum didn't drop.
But, I don't really care, just as long as this guy gets fixed up.

His symptoms? I'm wanting more information.

Fire up,hit the road.
How long before trouble?
How long before it will start?
I'm really curious about fuel flow, just into a jug.
I would drain the bowl and see if it's dirty.

When you have the carb apart check the height as well as the distance of the full swing.

ok. i will post pics later when i have a sweet wifi connect,, im almost outta phone data.

There were bits of crap in my tank, stuck to the fuel valve screen, at the very bottom of the bowl (jst lttle specs that didnt come out when i drained it. had to wash em out). my carb was kinda dirty.

Main air jet 280
pilot air 45
152.5 main fuel
52.5 pilot
I'll have y'all look at the pics b4 i button it up and try again. Dont knw how to measure float heights. also there are few things I'm going to seal up and clamp down so there's no chance of any vacuum loss.

Did you remove the seat for the float bowl needle and clean the screen on top of it?

I've never run more than the screen on the fuel valve. the last tank I had was freaking full of rust and I never had a problem with rust.

Are you holding the float up with your fingers when you took the picture?

The float looks like it is not at the proper elevation....I am used to seeing the mounting hinge more parallel with the gasket surface.

You need to check the float level (and clean the screen on top of the needle seat).

ok.. i cleaned out the carb nice and good, still starved for gas. was out testing it and all of a sudden it stopped...and thats wheb i realized my gas cap was about to fly off. IT WAS THE STINKING GAS CAP! It's a vented one but seals completely with this tank, or doesn't vent enough, or is broken. One slice of the rubber gasket gives me enough vent...hauls balls! It was a vacuum type thing. Serowbot!

I replaced the fuel hose with clear hose and installed a clear inline filter...all kinds off very small debris get caught in there.

Dave: Ya im holding the float all the way up. ¿Mounting hinge parallel to gasket surface? that wud mean mine is way off. Ur saying that when i pick tye float all tye way up it shud be parallel with gasket that seals the bowl?

The float height is measured when the weight of the float is on the needle.
