Does anyone know if the air stack on a 20 series the same as on a 30 series? Was there another option? I'm seeing some 20 series with an air stack like on the styled Gs and As...

Thanks

Anybody know the year cutoff?
 
The 720-730 gas parts book shows the straight air stack available for both 720 and 730, although different parts for each.
 
It must have been an option for the 630's also. My 630 has never had an air stack.

Yes, the air stack on a 20 series is the same as on a 30 series.

Take a look at the diagram below.

Note that most of the air stack parts for the 720 are the same as the 730; however, the air stack part numbers are different.

The air stack for the 730 has two additional parts the gasket (Key 14) and the spacer (Key 15) plus the longer cap screws (Key 13).

Hope this helps.

Ok, I guess I got my terminology wrong. I was talking abouy a pre cleaner stack on a 30 series and an airstack on a 20 series. I guess they had both for both series.

Yes, the pre-cleaner is the same for both the 720 and 730.
