Going back to a standard air box

Well the time has come where i need my runner and the great bristish weather isnt going to stay dry enough to run with a foam filter.

So i am going to fit a stock airbox back on my 172.

My current set up is a 172 pm kit
dellorto 25mm jetted to suit open filter
stock exhaust
stock rollers

what i was going to ask is i brought and fitted the upjet kit from pm for running an open filter. now im going bck to the stock filter do i just replace the mainjet or do i do the low jet and atomiser to suit.

i run my oil pump 2-3mm avanced and have covered over 1500 miles on the kit without a problem but needs must and i need a quieter more weather freindly runner

 

I would think drop the main jet a little.
