The manually adjustable flap was marked "winter" and "summer".

With everything properly tuned and mixture adjusted properly, the variable venturi carbs
are notorious for severe hesitation and driveability issues. Set the flap to winter position=problem solved. You could feel the air filter housing get almost too hot to touch when it was working.

More heat better fuel atomization, more efficient, better driveability.

already knew what hot air . I did not know what was best for that.


the first car I had, peugeot 205 GTX 1988 , powered Talbot, llebaba this system with a three-position lever, with cold air , intermediate position , or hot air, other cars and Opel Corsa B 1994 or seat ibiza 2000, both with single mono point injection , this system is regulated by thermostatic valve. Over time the valve is damaged, and remains open in hot air .

by the shape of the air filter box can only get air through the top. The top is connected to the air filter . the air filter box there clean air and oil vapors .


on top of the air filter box is the seat and there is little space , is not whether some small cave Tuveri .

there is very little room to pass a pipeline from the front of the engine where are the collectors to the air filter.


my motorcycle





another motorcycle without air filter box .
