The airbox on my cr250 has gaps and holes top bottom, left, and right, they made no attempt to make it water resistant. If I get in water only high enough to reach the bottom of the filter, it will get wet. There is no lid, just a gaping hole covered by the seat. I was thinking some pool liner attached to the box and frame would allow me to still take the number plates off without breaking the seal. Otherwise, I might have to silicone them right to the airbox.
Thanks for the tips on the carb hoses. I saw a kit by PC racing that does something very similar. Think I can get the Ts and carb hose at an autoparts store or is this stuff order only?
THANKS
