    Will the Airbox snorkel removal affect Ivans performance modification?

    I have the "Ivans needle/airbox mod. kit" in my bike, and was thinking about taking off the air-box snorkel extension to ease access and allow the use of a different battery. Anyone else done both these mods? Considering all the extra holes that are drilled in the airbox as per "Ivans" directions, I wouldn't think the snorkel removal would change the air flow but ya never know, so thought I'd ask to see if anyone has experience with this before I do it. Thanks...

    After looking at the amount of air holes located directly over the intake tubes, that's what I figured also. I called "Ivans" and the "tech" I asked didn't sound like he knew either way. He said I may have to change the main jet, blah, blah, blah,...but didn't have any experience with it. I have the lid off now, and after looking at it, I think I'm going to make the snorkel removable just in case until I can test ride it "with and without" it. (Minnesota is frick'n cold this time of year) Thanks for the input "shortlife". Happy New Year all.

    removeable makes the most sense to me too..honestly tho id be pretty hard pressed to drill holes in my airbox..aside from the one i did for drainage with large drain tube...afterall i ride in some monsoon rain and i flooded the airbox on more the a few ocasions

    I made it so that the end just slips back into place. So much easier now to get to battery connections, and will allow the use of the cheaper/more powerful but slightly taller battery when time comes to replace. I was "nervous" about the 20-3/8" holes drilled in the airbox top, that were recommended in "Ivans" jet/needle kit but haven't had any water problems even in a few DOWNPOURS. (haven't fjorded any streams tho...yet) Still kind of a pain that ya have to jack-up the gastank to check/replace a air filter tho. Small price to pay tho for whats been a reliable, easy to work on bike that lends itself to "tweekin" to taste!

    out here in the pacific north WET when it rains...your wet...i dont care how good your gear is your going to end up wet...its life out here

    check your drain in the bottom of that air box while your in there....mine was FACTORY plugged by foam....but even still with the amount of water i got in an UNMODIFIED air box was nuts..i drilled and tapped for a 3/8s nipple fitting on on side of the bottom neer the front for maximum drainage...i flooded the bike 4 times in a 250mile ride in the rain on the hwy

    I'll check, Was the foam their version of a air filter over the drain hole, and all plugged up then? I remember things being pretty damn wet out there (WA,OR) when I was stationed in the shipyards of Puget Sound, WA. (Seattle) You'd be the man to ask about best wet weather M.C. tires! I suppose that's a whole other thread tho? I have a 1/16th inch hole on the bottom where the air filter goes, that's covered from the underside with a piece of hard foam (crude filter), and then there's the "main air-box" (carb boots hooked onto) that has the drain hole with tube and collection bottle. I assume that's what is filling with water on you? WOW! I wonder what route the water is taking when your riding in the rain to fill it up like that?

    no clues how/where the water is going as my airbox was NOT drilled in any way..and still has the lil white snorkle on the end even....

    in the bottom of the filter is a tiny tiny tiny hole and there are a few rubber/foam pads glues to the box.....one of those pads went right over the stock drain hole...the last time i flooded the bike i did get it restarted only to flood it again about 10 miles down i5...stop...try try try wait try try try wait fire up like CRAP....blast another 10-15 miles came thing again..dead on the side of the road...the rain eventualy let up but i did this for 100 miles or more.....and eventualy got home..2 days later i poped the seat and the tank to have a look at the air box..figureing i should re-oil the filter...there was 2 cups of water STILL in the air box and she sleeps in the garage.....

    the stock drain was just a hole..no catch bottle....the new one is big enuff that ive actualy ridden in worse weather and not had a lick of problems....the lack of drain and lack of enuf drain was letting the box get enuf water into it to litteraly pour into all 4 carbs.......i make many runs from portland to victoria BC...and rain dont stop me..but more often than not im soaked before im half way home..but 80mph tons of water comming down and 250 miles...the gear can only keep it out so long

    Thats some "hard-core rain-riding". I understand the need for your 3/8" drain plug mod with that kind of history. After thinking about it, I went and re-checked both my drains and cleaned the air-box. (mostly just oil blow-by) to "make sure". Looks like next oil change in the spring, I'll only go about half way between the "marks" and see if that reduces the blow-by out the crankcase vent tube?

    Ann, how about you go clean something while the grownups talk about airboxes?
