So I'm finding my air box to be prone to catching water. I replaced my crank bearings about 4 mos. ago and then did a 6 speed swap last week and found my crank bearings to be rusty again. I ride in some extremely wet conditions here in the northwest and don't foresee that changing. Anyone noticed this problem & came up with a solution? It's a 09 300 and never sits for more than a week. thanks for any thoughts.

Hi everyone,
As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.
When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.
Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.
Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.
Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.
Thanks for your patience and support!

dominator known to cause rusty crank. Don't know about R50.

joedirt hit the nail on the head! water gets directed straight up through bottom of airbox when riding through water-crappy design but easy fix. either use foam to seal bottom of airbox(somewhat porous stuff that will still let water out but prevents it from getting in) or do like I did & clean airbox thoroughly then silicone seal the whole gap then drill a 1/5"(hey see no metric used for you guys
) hole in bottom/underside of airbox. work out where lowest point is in airbox when bike upright & on its stand for drainage reasons. I think it angles down to the left side of bike more than the right & rearmost point but youll work it out. makes it a submarine as takes a ages for water to fill it through such a small hole but drains rapidly. just check its clean/clear every now & then. never had a drama with mine since but did drown my bike from riding too fast through shallow water a few times before I did this mod. buggered if I could work out why as I had my carb breathers routed up into airbox(do this also-only the 2 that angle upwards on the carb though) then had a good look at airbox & found the culprit!

Yz250 air box identical regarding drainage outlet. Never a problem.
From amsoil website:
* Not suitable for long-term use in outboard motors as a TC-W3-type oil, although excellent as a race oil for short-term use where motors are periodically inspected.
I take that to mean that it lacks corrosion inhibitors. Interceptor is said to have them tho.

It seems to me the water is entering through the top of the box. no deep crossings just lots of shallow water in the trails I ride. the ims tank is not as tight to the upper subframe mount as the original i'm noticing. maybe some sort of foam insert as opposed to the little rubber mudflap.

holes in sideplates/rear fender, tank/seat juction & subframe mount point where rubber mat is(my money on this one) could potentially funnel water onto filter i guess. yeh bits of foam strategically placed should sort it. ive never ridden in real hard rain or very wet bitumen roads so never had this issue but done plenty of wet trail rides with no issues from water/mud

You'd think a well oiled filter would stop water ingress ?
Maybe rig up some sort of deflector ?
Would be pretty hard to stop all water with the amount of water we get around here.

Waterproof doesn't mean that it can keep the water from passing through the filter, it just means that the oil that contacts the water won't turn into an emulsified mess. Anything that could keep water out would severely restrict airflow......
