boingk said:To get the filter size (I'm assuming pods here) simply measure the outside diameter of the carbs intake side. This will give you the size you need to purchase. If its an odd size, say 34.6mm, [size=10pt]then round up to the nearest millimeter to avoid overstressing the rubber boot[/size]. If you plan on running velocity stacks, then its the inside diameter you want to match up.

Actually, you want to go the other way and round down. The boot will easily stretch a few mm - and you dont want to have an oversized pod that may not seal properly................or possibly fall off your carb somewhere down the road...
