  • 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 The previous version was outdated and no longer supported.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!

Friend of mine went down in a creek last week. He said he didn't think it got real wet, but to me it looked like it had. Bike would not start afterwords. Luck he was back at the truck basically when it happened. This was last week. He said he got it running and it ran fine mid week. Well today we went to ride and it was being a bugger to start so I had to bump start it for him. After I got it running and ran it for a few I looked through the sight glass and the oil was white. So I drained it, refilled it, ran it for ten then redrained and refilled. Oil now looks ok. Looking around the bike there was oil seepage around the entire right side of the case. So I checked the bolts and they were all loose on the Trans cover side. Did the water in the oil have something to do with that at all? On the left side the plug where the wires come into the case is now leaking pretty good. Any idea how to get it to stop, or should I replace the plug? Anything else I should check or do after the water exposure?
 
I wouldnt think the drowning would make the case bolts loose no. Id clean the air filter and change the oil filters. If it w a s relatively clean water he should be ok. Are you talking about the wires from the stator? Maybe a bit of crud got in there. Maybe pull it and clean it.
If it was a 4t husky then it is normal for oil to go everywhere when they are tipped over. Especially to one side, cant remember which side it is worse though.

When you drown the bikes fisrt thing I do is pull the air filter and ring it dry. Then use the kick starter slowly to make sure it hasnt got a gob full of water in the cylinder. If it does pull the spark plug and kick it over/use the starter to push the water out.

I didn't think drowning would make the bolts loose either. Only thing I could come up with is maybe the water swelled that gasket a bit then it sat all week and dried out and shrunk a bit making then loose. But maybe that way off base. As far as the wires go yes I believe they are the ones off the magneto. One other question is did the loom that covers those wires go all the way into the plug or is it normal to stop a half inch before the plug. When I pull that plug to clean it do I put any silicone or anything on it to reinstall?
 
It appears normal for the right cover to come loose as mine had done. 8nm torque to spec (6nm for oil filter cover) should stop slight oil weep shy of changing the side cover gasket.
 
The water more than likely came in through the head with the run down from the top end lube. I did the same thing to mine a couple months ago but, I was in a deep Louisiana mud hole. It locked up when it went under and I couldn't turn it over, which turned out to be a good thing, I got a tow back to my truck and went home. When I got it apart, I could look in to my intake and see muddy water setting on top of the intake valves and when I pulled the pipe I was able to dump about a cup of water out of the pipe (not good!). I pulled the plug, drained the oil (which didn't show any water), sprayed a lot of WD 40 into the intake and exhaust, then turned the whole bike upside-down and let it drain (a lot of crap came out). Then I turned it right-side-up and used a mixture of HOT water and Dawn soap poured in the top end and slowly kicked it over until I couldn't detect any dirt, this was a slow and tedious process because I didn't want to cause any more damage. Next I filled the gear box with a mixture of Sea Foam, alcohol and WD 40 and sloshed it around by holding the front break and rocking the bike back and forth on a center stand. I repeated this about three times and I didn't let this mixture sit in there because it's probably not too good for the seals. Then added oil, changed filter and added about an ounce of Sea Foam and ran it until it got hot then repeated this step about four times. Since doing this I've put about 100 miles of hard riding(as hard as I can ride) on it with no loss of power, that I can tell, and no other ill effects. I may have just got lucky.

P.S. Dirt Rider magazine has a article where they drowned a Yamaha YZ250F and then bring it back to running condition, good info.
