after i took it out i relized it had a hole in bottom and am now not sure which way it goes in. i'm guess it goes toward the air box side of the carburetor, and is this the hole that needs to be drilled out?

 

The slide will only go back in one way...and the hole to dril is..............

 

Fill that hole mudjunkie.LOL.

 

OK i should of provided some more information but I have a 07' Klx250h and the slide is simmilar to that one doesnt have the white pice or the hole on the back side like that but i can put itback in either way. It is an oem slide CVK 34

 

the slide goes in one way. the fins don't allow it in the wrong way.
