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 The previous version was outdated and no longer supported.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

gas in oil te449

I've noticed the same on mine. First couple changes, didn't notice, but the last was very prevalent. Filters were as clean as could be. Could dropping the bike a few times a ride cause this? Bike runs strong, runs cool.
 
Maybe an injector sticking open a bit. I have seen this on other brands of EFI bikes.

My 2013 TXC 250 with 50 hours on it does this as well. I personally think its due to it running rich on the low end. The rich mixture allows some unburned fuel to wick past the rings and mix with oil. I dont think its a huge problem if you keep up on oil changes and dont let too much fuel dilute the oil.
 
It's blow by. My breather bottle separates the oil from the fuel, putting the oil back in the crankcase and routing the fuel to the air filter.
 
Are you using the bike for long runs or just commuting short trips, as in does it reach full operating temp & stay there for a while?
Also, what EFI tuning have you done? (It may be too rich in the mixtures0
Breather should vent the fuel fumes to the inlet port once the oil warms up. A top end breather will help rather than breathing from the transmission.
Either the ZT one noted above or the DIY option also works well.
 
Please tell me more about this breather bottle or a link to where I can get it. I've been very interested in all of zip tys products. I do occasionally short trips bike stock with race map 2 plug

Except instead of going to the fill cap, it would wrap around to the drain plug.

The gas in oil prior to breather makes sense. I used to have the dye from marked gas turn the oil red. It looked like transmission fluid after a little while. I no longer have that problem since I have a re-circ system.
 
Tinken, can you explain the reasoning for running your drain back kit to the oil drain plug instead of the oil fill plug? Is this to prevent blow-by re-circulation?
 
Convenience and not having to put a rubber hose around exhaust. To drain oil, just pull center plug.
