My 50 did that at Ohakea. KERBLAMMO!!!!!

[F5 Dave]

and my 50 did that at Foodtown carpark in P.Nth (back in the days of no sunday trading). Leg out of bed & Gossimer cartwheeled over me & landed on top of my bike which was in turn on top of me. His bike made a break for it & continued on.

No bullshit - but no sigar either, Wob. It is simpler than that. The inhaled air enters the duct from all sides (hence the positive effect of a bellmouth),
but the blow-back shoots back out in a single column that hits the piece of paper in the video.
(Of course no running engine can blow back more air than it inhaled ).

Clever but wouldn't the air passing back through the carb venturi also have an effect when the air is blown back????

Plus wouldn't it be sucking over a longer period of time (A long deep breath)than it was blowing back (a fart)

Yes, but that's all in the game of finding a jetting that makes the engine happy.

Depends on the rpm; at low revs the crankcase is filled long before a piston-controled or disk-controled inlet port closes. The kinetic energy of the blow-back may even create an underpressure in the crankcase. And if the revs are really low, that underpressure can cause a restart of the induction process so that the engine inhales once, blows back once and inhales a second time, all within one inlet open period.

In the light of this, does it make sense to think this could also happen with a membrane inlet?

This is the second go on a different RZ with a given carb and its again the same deal, have to use a realy lean pilot jet (because of double dipping ?) but then when opening the throttle the slide needs to be really rich (since no more double dipping, then the pilot shows it's true colours?)

And, if all that is true... what would one do about it or is it just a case of jet accordingly?

edit: seems the case only with this type of (modded) carb btw

[F5 Dave]

air leaking past those bored 26mm carb slides?

[ief]

No, vm28's with dave f mod. (basicly making them like yds7/ yr5) Thing is, I seem to be the only one encountering this as far as I can tell. Prolly something stupid on my side but can't figure out what
