flow rites install on cowling questions?
I did a search on flow rites on seat cowling and read all that i can before posting.
what size hole saw do i need 2-3/8 or 2-7/8 as per geo or 2-1/2 as per jerry.
on the seat cowling there is 2 sides of the cowling one inner (inside engine)
and 1 outer (outside) do you drill from outside and thru the 2 nd layer inside??
any help would be nice here are some pics of my cowling

Not sure if these are what you're referring to but I had some 2" ones and a 4" on my snowmobile. They also make 2.5" ones.

It says which size to use in the Riva Rear Intake installation instructions..2 3/8" is the correct size hole saw to use. I drilled through both sides of the cowling. That's the point of the mod; to allow hot engine compartment air to release. I start on the inside so anything that might get chewed up is on the inside, not the outside (where it's visible).

I have 2 in my grab bar and 2 on each side of the engine cowling. The ones in the grab bar are so the rear air intake can breathe. The ones in the cowling are for ventilation. I was going to install 3 in a row on each side, but I installed a 3" speaker on each side instead

sorry guys here is my install i read thru the search and used a 2-3/8 hole saw
did like you said jfizzler thru both sides,but i started from the outside to the inside drilled thru both.you have to trim then make the oustide cowling thinner with a dremmel and they all cliped perfect and where the 3 clips are you must make sure it clears bothe sides,if not it wont go inn and clip.
