Seriously, if your bike keeps dying on the four lane at full speed and you can see that the clear fuel filter bowl is empty (no gas) that slowly recovers when you stop then you may well have a stiff diaphragm condition on your petcock.
You could also have a dirty petcock filter, bad vac hose, and a half dozen other vac petcock related things going on that all can combine to give you "the condition".
On the Savage engine we know vac suction goes down a little bit at full speed and a stiff diaphragm (or all the rest of these petcock thingies) will combine with that to occasionally fuel starve you on the full speed runs.
This is just one of many vac petcock illness scenarios -- you can fight them one by one by replacing vac hoses, using clamps etc (which all attempt to coax the petcock to work a little bit better for a short period of time).
You can keep on struggling along for years and years, rebuilding it and replacing hoses, etc. questioning your jetting and stuff like that. Aggravating stuff.
Problem is, the diaphragm gets yet stiffer with age and then it finally cracks and starts leaking fuel then you get a whole new host of new contradictory funny acting symptoms to deal with.
Mod boys with high performance engines very quickly learn that the stock petcock CANNOT flow enough gas to feed their high performance engines on full speed runs -- we live in the world were the petcock
really shows itself as a very clear troublemaker.
After a while, our Johnny Depp comes out and we stuff the durn thing down the mouth of the cannon and we see how far away the splash comes when we finally send the durn thing off to Davie Jones locker.
Now, how long will you put up with it until your Lorana comes bubbling up and you go all snicker-snack on it?
A Raptor replacement STOPS ALL THE NONSENSE FOREVER ... it just works, flowing
a whole lot of gas when you need it.
jest ask yer hubby if he loves you ....
