drr 90 carb size

[Bodie1]

How can I tell what size carb is on my 2007 drr 90 ? I was told it was a 28mm but want to be sure before I buy an air filter for it. I know its not the stock one, quad has some mods done before I bought it.

You'll need to measure the inside diameter of the carb where the filter attaches. You'll want to use a micrometer in millimeters. Probably a 24 or 28mm. It may say on the side of it as well just above the float bowl.
