    STX-R engine removal with or without carbs.

    Can the engine be removed and installed with carbs attached???

    I have to replace the drive shaft holder assembly.....was wondering if I needed to order the carb gaskets or not for reassembly.

    You do not need to entirely "remove" the engine if you are replacing the drive shaft housing assembly in an Ultra-150.

    I did mine simply by raising the engine up a couple of inches to allow the drive shaft to move forward - and the carbs were certainly still attached.

    I bought mine from here:

    If I remember correctly - I had to pull the pump to get the drive shaft back where it belonged - as the splines would not line-up with the pump still installed.

    I did not use any silicone upon re-install as everything was so clean:

    PS - Just read Title and OP has an STX-r. My information shared pertains to an U-150, hence I cannot confirm OP's question. Sorry for not reading the Title first (Hey it's early here ~ 4:15 AM)

    You can re-use Kawasaki carb gaskets. If you've got cheapo aftermarket cardboard gaskets, throw them away and buy new.

    Nah when I build the engine I used all Kawi parts.....had I know these were troublesome I would have replaced it with new.......I figured rebuilding the thing with new bearings and seals was good enough....oh well now I know.

    Wasn't cheap to get all the stock parts to rebuild it either! Waste of my time.....either way engine is out, took a leisurely 2hrs start to finish....part should be in today then reassemble. I didn't remove carbs completely, just unbolted and flipped them up onto the engine to leave all the oil lines attached. Wasn't fun to safety wire them in the first place.

    Yeah I thought about that as a possibility but the first time in I had the same problem.....everything went well except trying to get the shaft into the impeller......so I just made it easy on myself and got the engine out of the way so I could work. it's really not bad, you can unbolt them and flip them right up on top of the motor and leave the oil lines attached. I used the copper spray on the gaskets so they slid right off with no damage to the gasket. It took all of 3 minutes to just flip the carbs out of the way. I was just trying to save money on gaskets.....I get them from Kawi so it's time and money.

    Thanks guys!
