gas going into oil res and oil getting into intake boot

[ride.race.live]

Hey guys,

Need some help!

my buddys 06 ltr 450 is having some issues.

His oil reservoir is filling up with fuel and his intake boot gets covered in oil.

Any ideas of what is going on???

rings are wore out at the least.

how much fuel? does it just smell like fuel or is the crankcase full of fuel.

the reservoir is filling up to the point if you take the cap off it overflows.. and smells like fuel

once it gets overfull the bike will just stall out like the crank case is full as well.

Leaking injector.

Did you fill with the proper amount of oil when it was changed last?
It seems the only way fuel can enter the motor is through the throttle body. Since the FI system requires a fuel pump and proper fuel pressure to operate and it isn't gravity fed the amount of fuel that would pass the injector seals while the bike was parked overnight would be miniscule and would have to accumulate over time. If you've changed your oil properly, how long did it take for the problem to surface the second time?

yea the oil changes where done correctly.

Im not quite sure how long before the oil res was full but it was within a quick ride... so within 1.5 hours to say the least... ill try and find out exactly

If you're passing raw fuel into the throttle body while you're riding the bike wouldn't run correctly.

[ride.race.live]

yea true!... he said it seems to be running fine.

He said within 15 - 30 minutes he starts getting fuel in his oil.

That doesn't sound right. blueranger is correct. Doesn't seem like we are getting the whole story.
