Warning - DO THE WATERPROOFING AND MUD MODS NOW
Posted July 22, 2004 - 02:34 AM
Do a search on the crank case, carb vent and other mods now, submarine your bike and save a huge bill. I have one coming that is going to lay my bike up my lovely new machine (used to be) for a long time. I am going to miss trail riding big time, and the payments keep coming.
Save yourself my grief and do the mods now. P.S. I never did anything all the other bikes (mostly CRF's) I was with do.

Also the carburetor breather hose.
Do it before your next ride.

Water/mud/crap could have also gone down the exhaust settling in the headpipe and most likely entering your top end.
The only other way I could see causing this is your filter not being completely sealed and/or comprimised with the water entering the air box entering the carb then top end.
Moving the vent tubes from the carb will prevent your engine from stalling once the bike is in the water but has nothing to do with crap getting into your topend IMO.
I haven't moved my breather and I have been in water as deep as bottom of seat. Luckily I haven't dropped it in the drink yet. If you ever stall in the water, DO NOT try and start the engine if the breather is underwater.
Push the sucker to dry land. Stand the bike on its butt, to drain any water from head/tail pipe. Then take your filter off and wring that out until relatively dry. Once you get out of there kill the engine and do an oil change or 2 or 3 until no milky white is seen on dipstick and/or when you drain the oil out.

The oil screen in the inner sanctums was clogged up and the top end starved a bit. I didn't drive a block in this condition since it happened close to home. The dealer doesn't seem to have much sympathy (they have a monopoly),they said they synthetic oil I was using probably saved the top end. The cams aren't perfect but they are going back in. P.S. No water or mud in the air box carburetor.
I am going to write Yamaha and official letter explaining how I feel that the cylinder head breather hose design is not designed well for the intended use of the vehicle. I was only in about 6 inches of mud. (so were the CRF's but they have a better design I'm told). I'll try that, I'll try small claims if necessary. If it can get a letter or fix out from Yamaha and save another WR dirt biker grief it will be worth it. A stupid design if I say so myself.
Good news is the CMRC Nationals will be in Riverglade this weekend coming, and they are a piece of heaven to watch.
Go luck all guys and girls entering.

I did the breather hose "tee" mods, but did not want to drill a hole my air box, so I tied the high hose ends up under the seat with a foam sock on the ends.
