Jssrvlz Im going on a bit of a ride tomorrow. Ill for sure learn about anymore issues. I just wished I knew about the possibility of water being sucked into my tank.

Thank all you for your great ideas

KodiakAfishyo That's great that you were able to figure it out and especially being a cheap fix & nothing major.

TRW Like Vincent says, "This is very weird one."

We really need to get to the bottom of this! I am so glad for you, and good job following through and getting this solved.

Jssrvlz And today I did an oil change, and a rear diff, front diff oil change as well

Jssrvlz Update.

I feel that the oil was possibly just grey or dirty and possibly just had a touch of moisture in it at worst. I change the oil, and it seems to look nice and pretty.

As far as water getting in the CVT housing, I'm still not completely sure about that. Maybe a vent tube allowed water into the CVT, or possibly the hose clamp on the boot wasn't tight enough. Either way it is dry now and seems to be running just fine.

The main problem seemed to be, the gas tank was full of water. I'm not sure if it's because the gas tank had a negative pressure in it, which allowed water to be sucked up through the vent tube in the rear, but that's what I'm thinking.

So by siphoning the gas out of the tank, unhooking the gas line from the fuel rail I'm seeing a bunch of white, refilling it multiple times, adding heet iso cleaner, draining it more, taking the injector out and cleaning it, I have finally got it running pretty dang good.

Unless there are some residual problems because of this, I believe it is close to fixed for now. This last time I ran it it didn't try to die one time. I'm so thankful currently

The lesson I learned is do not park your machine in a creek after you've ran it for hours, cuz some vent tube just met suck water right up through it

Colorado Kodiak 700 Don't underestimate the Yamaha engineers. They put a lot of time in to cover all the possible issues, or as many as possible. The only thing on these things that might need attention for normal riding is the air filter coupling.

TRW Interesting, I will casually observe it in the future. My nature was to ad a foot of tubing onto it and loop it up to be sure water did not get into it.

I "believe" it's an indicator if the water pump / oil pump seal fails. Under "normal" circumstances it will not let contaminate in, if a seal has been compromised it will leak some fluids on the ground. Again I'm not 100% about all this, but looking over at my stator cover when it was removed it "seemed" like that mite be the function of it.

What year is your?
All 558 and 686s have that tube leading to no where.
It's actually leads to your water pump bearing area. I'd post you a picture of my stator cover removed showing this but this forum has some bizarre limit on posting pictures / Attachments.... Lame!
