    ? about a sleeved ultra 150 motor

    I bought an 99 Ultra 150 that wasn't running. It had low compression on the rear cylinder. I took it apart I found out it's an SBT motor with sleeve cylinder. My question is if I bore it and put in new pistons assuming the crank is fine how long should it last with sleeved cylinder?

    properly maintained it will last just as long a coated cyl.
