250-500cc 2012 wr300,keep sucking water!

Is there a mod to fix the big gaping hole in the bottem of the airbox? it shoots water directly into the air filter on little water crossings,causing me huge running problems.

In wet conditions I run a big chunk of skid plate foam in the bottom of the air box. Keeps the splash under control, but allows drainage. If it's really wet I'll run a water repellent filter cover.

FYI- You can't get a OUTERWEARS pre filter for a Husky, so I use a Honda. http://www.outerwears.com/proddetail.asp?prod=3615

I have tried putting skid plate foam,didn't help much. So today I completely blocked off the factory drain. I then cut a 3/8 by 1 1/4in hole on the exact opposite side of the box,I then cut a piece of thinner rubber and riveted it over the hole on the outside. So now water can get out,but not splash in. Some kind of monkey designed the factory one.What were they thinking?? the rear wheel sprays directly at the opening and its a straight shot in. So hopefully My Little mod here works better.

can you take a pic?

I will when I get a chance,been super busy.

well,I dpn't think its water at all now. Its the stator or coil,have barely any spark,which would explain the misfire and back firing. This bike is really starting to piss me off.Now I might miss my favorite race this weekend! I shouldn't have these issue's with a bike that is only 10mo old.

Take off the kill button and see if that helps.

Sometimes it shorts a bit.

Check the coil grounds too.

did that allready

vent you carb vent tubes to the air box, i had the same problem on long deep water crossings, the bike would stall and when you try to start it with the vent hoses in water it will suck it up and make it worse, i havnt had that problem since i did that

Ive done that allready too! lol

im stumped

I have my dealer working on getting the stator and coil for me,They are good at helping me out.

Another waterproofing thing to check that could mess with the spark. Check the stator cover for a recess on the sealing edge, if there is a cutout for draining it will obviously drown the stator when going through water crossings. Epoxy or JB Weld the recess away and just make sure to pop the lid after a ride to let the condensation out. My old CR 250 would die after a water crossing and I'd have to kick it with the cover off a jillion times to dry it out.

fixed it! it was the coil. purrs like a kitten and is much easier to start. Thanks to schulz cycle for hooking me up. Not bashing But if this were any other brand bike I would be sitting on the sidelines this weekend.

yep,mine was kicking back also,they said they have seen a few of the coils going bad,even new from the factory.mine was coming and going,never consistant enough to figure out.It finally was consistant enough to find a weak spark.

do you still run the mukuni?
