Does anyone have the details on how K&N jet sizes convert as compared to stock jets for a 400ex? Thanks

Pretty sure K&N uses the same as Dynojet.

There's a rough conversion chart around here somewhere...

That's what I had heard (conversion chart) but couldn't locate one with search. Thanks!

Here's a good thread with a conversion chart. Read gpracers quote at the bottom of the first page:)
