THIS is why you add an inline filter

Well slap me stupid. Went on a 20 mile run and..while fighting a 20-30 headwind at only 55mph...it did it again. pulled over, waited two minutes and finished the run no problems. Tank off this week.

Around 1 to 1.5 gallons in tank

650ed,Thanks for that info.

Have checked out the site, found filter, will give them a call tomorrow.

Also checked out the bowl screen on ebay.

$10 inline filter from autozone. Time to clean my tank.

Update:
Tank off, shined a bright light in there, I couldn't see any thing outside a few specs of crap floating around.
however: Pulled shook, shake flipped flushed..put back, still no joy.
Pulled petcock (recall the story of modifying it to 'on' or 'off' bypassing vacuum setup) tore it down, ran a 1/4" drill thru all passages (instead of the metric slightly smaller equal) put back, pressure test to 30 psi, no leaks, it goes back on bike-
Pulled line off petcock, 1/4" dia stream of gas, pull line from in front of filter, stream.
pull filter..nothing!
inspect new filter, some tiny specs of something, carb cleaner flows right thru like water..grrr..
Wipe off edge blow gently and air goes right thru (yes, arrow pointing fuel flow has been correct all the time. ) put filter on, trickles..stops..nothing..There is only about a gallon of gas in tank at this time to try and simulate the 100-120 mile fuel starve problem.
Tossed paper filter, put screen filter I had in box that I didn't use when this problem started last year........zing! Flows fine- put 80 miles on with passenger and no problems, will put more on when storm passes.

Lessons for those searching years down the road with same problem
1) ALL paper filters are not created equal
2) All "free flow zero g" free flow paper filters are not "zero g free flow" This one would flow with 4 gallons sitting on top of it, but NOT one gallon!!
3) you look more awesome riding your bike, than sitting on the side of the road pretending to use your cell phone.

petcock screens, inline filter and never remove those inline screens in the intake side of the carb gas rail

These inexpensive and well-performing aftermarket in-line fuel filters are available off-the-wall at most motorcycle dealerships, motorcycle repair shops, and many other small motor repair shops.

Haven't tried this slimline version:

Good Fortune!

Here's an interactive demo of pressure/height relationships.

Watch the outlet pressures change as you move the guy up and down the hill, and as you change the level inside the tank.

650Ed,

I have followed your advise ( April 2012 ) and purchased two petcock in tank filters from reproductiondecals.com.

Ready to install filters. Filter appears to be same dimension as petcock brass tube.

Looking at your pictures : it appears something is around the tube ( a band or sleeve ) connecting filter to tube.
How is this connected ? Both tube and filter same size.
(Perhaps, band or heat or chemistry or some combo. )

Also reserve filter opening is larger than filter therefore loose.

Have cleaned and relined tank with Por15 method. Will put up images when project is finished.
Got new o-rings for petcock and tank cap.

Thanks for your help.

On mine the original screens don't have a separate band or connector. The one screen fits over the extended brass tube and the other screen slips inside the depression in the petcock casting. If the screens they sold you don't do this you may want to call them and ask how they are intended to fit. If there's a problem with the fit they must have run into it before because they've been selling the screens for a pretty long time. Hopefully they have a satisfactory solution. Ed

Thanks 650Ed,

I will call them tomorrow.

650Ed and others,

Spoke with reproductiondecal.com, their experience is that the filter should slide over tube.

Upon examination : The petcock tube is flared at the end.
Choice of cutting off 1/16th or so; or a add a sleeve.

Not certain of problems in shortening brass tube, went for a less permanent solution first.
Using a sleeve cut from the cap of a Bic pen : snugfit for filter and onto tube.
If gas does not dissolve the plastic it is a good fix.

Left old filter on the reserve location.
