    I went in to buy a Stihl KM 90 powerhead today and they were sold-out -- so my dealer offered to give me the KM 110 for the price of the KM 90. In looking at the specs, may not have really gained much in power or whatever with the 110 over the 90. Bit the bullet and go the 110 anyway.

    I think I'm going to run the synthetic oil. I'm new to these 4-mxes and I'm still not too sure about them. When running the Stihl synthetic oil and high octane gas, do any of you guys still need to de-carb the exhaust port after alot of hours?

    I put a few ounces of SeaFoam and Yamaha Ring Free in every container of pre-mix.

    Keeps all of my 2-strokers happy and clean!:cool2:

    I don't work in a Stihl shop, but I do see a few Stihls and if you are using anything other then Stihl oil you will see carbon in the port and the muffler as well as the valves. Personally, IMHO, I think Stihls are way over engineered
    Next time you are at your Stihl dealer, ask him to show you the Stihl comparison test they did with different oils and the 4 mix engines, it will surprise you :)

    My KM 110R came with a kit to re tighten the vales after so many hours

    I agree, I really noticed a big difference on all my sthil equipment as well.
