Hi,

What are the venturis for that the Japs are using on their 160's? A friend of mine said it makes them more fuel efficient plus you get more power.

Also, they seem to come in 3 different internal diameters, 8, 9 and 10mm. Anybody know what one they are using? I was told the 9mm one suits the 160 best.

Cheers,
Angus
