it usually rains a lot up here in humboldt, although it's been really nice lately.....i was thinking about doing this as well, just wondering about the whole rain drainage issue. i've already had to "modify" my hood vents to not leak over my distrib. (fixing the po's attempt). would the water just go right down the pipes & out the bottom of the air box? or are there other drain holes somewhere else? maybe u can cut an angle on the modded intake tubing to act as a splash guard? any thoughts?

Dukie, with drain holes at the bottom of the air box left open wouldn't this allow water from a high river crossing to come up through the drain holes and get water in the air box? 
If this is true any thoughts on a flapper valve to let water out but not in?

good god i hope you're not in the water that deep for long enough for that to happen. The holes aren't very big. It's a good suggestion though (although i don't think there would be enough pressure to open the valve to get water out, especially with the engine running).
I've considered just sealing the drain holes up completely. From what i've seen water never makes it into the airbox from the cowl anyways, to the holes may be hurting more than they are helping.
I'm open to alternative suggestions to test out

Plug them with something (rubber plug, chunk of pencil) and run it for a month then see if you develope any issues. I dont think it would be a problem not haveing holes. The little bit of water that does get in would just evoporate.

i haven't really put much thought into the needing to plug the holes since i don't intend on ever doing any extended river crossings with my rig like....ever....but it's a good point for someone who may
