Justin, you didn't really just tell him to blow his own petcock did you?

...... you did, didn't you?

Do you really think his hose is that flexible?





"Hyucckk Hyuckk Geesh,,"  indeed.    If he clears his own filter blocking external obstruction he's gonna spurt a fresh flow of gasoline into his own mouth.



Seriously now, it might be better to tilt the bike over and take the Raptor off and clean the screen with carb cleaner.

Has anyone considered some sort of sock material to go over the internal filter screen protrusion on the raptor?   Something fabric, like the finger off an old fabric glove?   Something just to pre-trap the gross amount of rust flakes for those of us who have rusty tanks?  

There is plenty of room below the screen to tie the finger off and the finger could stick up well above the tip of the filter giving lots of surface area to pre-screen the trash.   Such a rig wouldn't stop everything, nor would it stop the fine filter from plugging up, but it would take a whole lot longer for it to plug up again.

Not gonna happen,,the hose will be full O air, for the most part, all that need to happen is blow a few CC's of gas back thru those screens. IF he does that AND flow rate pick up, he knows the screens are nasty,, BUt, as you say, theres  easier ways &, based on his T/shooting to this point, its pretty well narrowed down. A tank vent problem would take longer to show up. Hes seeing problems when the bowl gets run low a lot sooner than suction buildup in the tank could happen, even if the tank was full, BUT, If ya wanna test for it, its easy. Fire it up, ( assuming tank is near full now) time a run & not HOw ya run it,not how long it takes before it starts stumbling,

Remove most of the gas, do the test again, If it takes longer for the problem to show up, its a vent problem,
Decrease head pressure on the petcock screens & it pass more fuel? Not likely,, BUt, it will take longer for a vacuum to build in the tank with less gas in it.

Charon... Prophet of Doom... that's kinda' close... ...

 
You know, a newbie reading us tease each other might think "bad", but it's not, it is just some gentle ribbing going on.

Once you been through an oil war or two this is all very very mild, really.   Sorta like getting shot by a nerf gun instead of a AK spraying
7.62x39 full jacketed tracer all over yer butt (the willie pete burns ya some, it does).

  yeowie !!!

If we find the Raptor has somewhat quicker screen build up & clog up then we'll start mentioning the "finger" trick to the rusty tank newbies, along with whatever tank coating seems to really stop it for good.

When you look at gas flow, remember you need a cup full every 60 seconds to feed your Savage properly.   If you get 2 cups a minute you are relatively normal compared to most filters Charon has tested.

I use a glass turkey baster for this kind of thing,.. when compressed air won't do, and I want to shove some icky fluid through a tube or port or other sort of "orifice."  
-- Nylon works okay in most situations instead of glass, but sometime you might have to deal with a chemical that attacks nylon.  
-- Glass is pretty much impervious except for a few acids we would most likely never use.  
-- Don't let any of the icky fluid touch the rubber bulb.

here's an example:

above the float valve.

it's stuck to the top of the seat.

Splash,. I'm not going to go back and read this whole thread,..
.. but, your problem seems to be fuel flow...
Start at the top, and work your way down...
Gas cap vent, petcock screen, fuel line, float needle screen, float bowl...
floats...etc...

The screens on a petcock are very thin & fragile. If the tube they make is flexed any, one side is torn.
