97 mxz 670, where the fuel line goes on the carb there is a white plastic piece inside. is this a filter of some kind. if so, i think i read on here before that these should be removed. am i right. my idle has been kinda rough lately but carbs are clean and synced. it will go up to around 2000 rpm then slowly drop to around 1600 then slowly go back up. any ideas if this isnt the problem?

Not for sure, but if i recall there was a service bulliten to remove these. You have to have an in-line filter installed if you do this.

Service Bulletin issued on that. The small conical filters need to come out.

i took them out and they were close to halfway plugged. isnt there a filter where the fuel line comes out of the tank?
