Free breathing is always a better way to go. However the snorkels were probably 
designed for cruising and not for constant WOT. The snorkels are actually 
venturies that accelerate the air then drop it for the air cleaner. Lots of 
turns in the rest of the delivery system. Straight into the carbs is probably 
best.

 Has anybody got numbers of data on the stock 140 or 110 LM air cleaner 
snorkels?

Okay, tell me how this works: I spent a lot of money on the performance 
carburetor modifications done by our friend Mr. Young to improve airflow, I 
spent more money on the custom three angle grind on the valve seats to improve 
airflow, I installed, at great expense, the "slant" exhaust tubes and custom 
equal length headers to improve airflow. Now, I'm looking at the intake system 
and I find two small "snorkel" intakes on the stock air cleaner. The 
cross-section of these intakes appears to be less than half of the total area of 
even the stock carburetors. It seems to me that this would be kind of like a 
marathon runner trying to breathe only through his nose. What was the General 
thinking when he came up with such an apparently restrictive air  intake?. Would 
I be better off replacing the stock (but attractive looking) air cleaner? How 
about just removing the "snorkels" and perhaps putting some more holes around 
the perimeter of the stock filter? Is there a recommendation for a
  low restrictive air cleaner on a 140? Thanks for your help, I am always amazed 
at the depth of knowledge on this site.
