It may sound daft, but let me set the scene:
At my last service (or maybe the one before) the guys did a carb clean for me, and told me it was full of water. So I was careful with the cleaning from then on.
Today, I nipped into to town for some food shopping, with the intention of carrying on into the big city. About 250 yards from my house, it died at idle, "bloomin valves again" I thought, as I started it again, and carried on into the super market. When I got there, it died again, and would only give me a few sputters trying to start on the kicker (turned over on the button, but no fire). So, panicking about getting to work tomorrow, I pushed it around the block to the motorcycle garage.
When I got there, there was a queue of five scoots, all "won't start", "just died", "I pushed it here" and the guys said they most likely wouldn't get around to mine today, so I asked them if I could go get my tools and try myself in their car park, which they were happy with.
I pulled a few plastics, to get a good view of the engine, pinched the fuel line just before the filter, drained the carb until the filter was empty, returned everything back to normal, then started it. Vroom vroom. First time on the button. It idled nice and strong, until it bogged and died again. So I opened the air intake up and cleaned it out with a rag. Water, mud, vermin, Bigfoot, it was all in there.
The problem: rain. Not massively heavy, just fairly constant. And where the air intake is about 6 inches from the rear wheel, it sucks up a lot!
I was just wondering if anyone has ever fitted a snorkel like device (think submarines, British Army Landrovers, etc) to move the suction away from the ground and the wheel? I was thinking anywhere high, and preferably tucked away under some plastic somewhere.
Any all ideas welcome, Ian

try it sounds like a good idea has to be sorta perfect tho, no leaks and still has to force enough air in but not to much. ima guessin' after making a "snorkel' you will have do a lot of fine tuning to get the a/f ratio correct. just like you have to do with a uni filter.
what kind of air box do you have now?

what are ya, deep sea diving, joke joke. lol. the only thing I can think of is routing a flex tube from you're air box to the uder seat storage. cut a hole in the storage and adapt it in. then, like tuning the carb just right for that setup. probably you'll be running it leaner. someone else might have a diff opinion on your situation, but this should sufice. don't know if it will work or not, it's just a guess. I know with my 94' t-bird I had home made ram-air, but evertime it rained I had to disconect from the bumper so it wouldn't suck in water. tell us what works when you figure out how to keep the water out. I'm sure that someone eles could use the info.

I was thinking a seal wouldn't be strictly necessary around the existing intake, more of a splash guard between the standard intake and the snorkel, ensuring the majority of air is dry, but I'm not sure.
I'd definitely make it oversized to minimise the lean running issue (if I could make the snorkel twice the cross sectional area of the existing intake, I think that would be enough).
I'd also like to incorporate some kind flap Vv, to block off a full bore of water going through, but that would take some thinking to work right.
I'm gonna have a mooch around some DIY stores at some point and see what strikes my fancy as a possible option.
