according to a article i was reading this is how it goes when it comes to air flow jetting(my question follows)
Air filter:
Remove snorkel:1-2 sizes larger on the mains, adjust airscrews
Remove airbox lid:1-2 sizes larger on the mains, adjust airscrews
Add foam air filter:0-2 sizes larger on the mains, adjust airscrews
Add K&N air filter:4-6 sizes larger on the mains, adjust airscrews, add one size on pilots if necessary
Add 2 into 1 Foam air filter OR dual carb-mounted foam filters (removing entire airbox, NOT in addition to removing snorkel and airbox lid above):2-4 sizes larger on mains, adjust airscrews, add one size on pilots if necessary
Add Dual K&N carb-mounted air filters (no airbox, NOT in addition to removing snorkel and airbox lid above):4-7 sizes larger on the mains, adjust airscrews, add one size on pilots if necessary
Add Outerwear:no change
Add TORS elimination kit:no change
Q.#1 now does this mean if i have a k&n air filter with the air box and no lid and no snorkel i need to be 6-10 sizes larger on the mains?
Q.#2 according to above adding dual foam pods with no airbox i will have to go up 2-4 on the mains and adding dual k&n pods with no airbox i have to go up 4-7 on the main...so this means the foams are more restrictive so would i be correct thinking they would allow less small dust-like particles as well in turn protecting my motor more?
