Msx110 Oil Problems!!
I am working on 2 2004 polaris msx 110 w turbo's both have the same problem! The customer said they changed the oil and they slowly started losing power no the won't get above about 2500rpm. When I first started I checked the intercooler and it was full of oil plus there was some oil in the intake. I bypassed the intercooler with a piece of hose but it still won't do any better! The customer put to much oil in it I changed the oil and filter also! It starts and runs good it just won't get over 2 bars of boost and about 8mph that is what it was doing before I started working on it! I checked the compression it has 140psi per cylinder. Can anybody give me an idea of what to look for?

Greg, I'm certainly no 4 stroke expert on these things but I recall the sensors and intake gets full of oil and until it's all cleaned and sensors replaced you will not solve the problem.
Check the tech section under 4 stroke Weber and you should find the procedure for cleaning and repairing those rides.
It will also tell you the proper technique for filling and checking the oil level.

If the oil is filled up to the Full line when cold, it is over filled when hot, and the oil gets pumped into lots of places it should not go.
I think some owners have gone as far as re-marking the oil dipstick;
Full Hot, Full Cold, Low Hot, Low Cold

Classic case of too much oil. You will probably have to replace the sensors...check the service manual on this site for the list.
Every brand of 4 stroke skis has gone through this learning curve...the owner doesn't realize that, with a dry sump system, you HAVE to run the engine for a short period, in order to check the oil in the reservoir!

I would think the O2 sensor will NOT take a cleaning.
The other sensors uhhhh maybe, try cleaning them with brake clean or better yet electrical board cleaner.
