I`m looking at any and every possibility to explain the 99 jets in this thing. I did have rubber extensions and now I tied the two together with a long slit 1/8th wide in the BOTTOM of the bend so it clears the air filter top/scoop.



with the air cleaner on it normally wouldn't be an issue. and you don't want the slit on the bottom since the incoming air (to the carb) could potentially create a siphon effect on it.
without the air cleaner on is when you would normally see a problem, mostly at high speed from the air rushing into the scoop and over the vent tubes. that's when a tube connecting the vents and a narrow slit on the top or side side might help.
