Hi. Got 1999 yz250, my intake rubber/boot is ripped. Im looking for buying new one, it's hard to find 1999 model, what's the differences between 99-00-02 etc? Btw my carb is Dellorto PHBE 36 HS, so Im not even 100% sure is it 1999 intake boot right now.. Engine&frame is 1999. I'm grateful for any help and sorry for my bad English..
