    sbt motor w/ 00' 150

    ANyone know the spec/part # of the Wesico piston to replace after a bore on a std SBT motor 2000 Ultra. I refuse to deal with SBT, 4th motor that went. And what size should my bore shop make the walls of this piece of **** motor. I just want it running again and dont have the money for a new motor, the bottom appears fine, just the pistons and clyinder are shot...Was told I could go one over on the more.
    Any help appreciated.

    found it kit WK1268 80.5mm (305.00)
    Wonder if that sleeve can handle a 81mm (.040)?

    Watch E-bay. I have seen plenty of top ends, even jugs sell on there for very little money. Check the Kawi classifieds. ALOHR had a couple of Ultras he was parting out that sold, but I bet he could find you what you need.
    Also check with . The guy there to talk to is Brandon. Good guy and great customer service.
    Good luck.

    Take a look at wsm or stock kawi pistons. I used wsm on mine when I rebuilt this winter got about 20 hrs on it. Everything looked great when I changed heads last week.
