    what engine for ultra 150?

    I am thinking of rebuilding or replacing my engine in my 1999 ultra 150. Sbt sells engines with a 2 year warranty for 1850.00. My dealer will replace the engine with a new kawaski motor, parts and labor 3000.00 with a 1 year warranty. Has anybody bought a SBT motor? Is there anybody else out there that sells motors or rebuilds existing motors?

    I would say no to the SBT just because they use steel sleeves in the cylinders instead of re nikasil-plating them. Many people have had issues with the steel sleeves and they do not last in an ultra for some reason. If you can buy a short block from them and then have your cyliders replated, you would be much better off, or have Kawi do it.

    rebuild

    REBUILD it yourself. Their is nothing hard about this motor, Everything is basic bolt on. Get yourself a manual and let someone walk you thru it if need be. You save money and know your motor better. I second the NO SBT.

    Are there any rebuild kits out there? How do you go about getting a shortblock re-treated?
