    GS1000 Piston Kit

    OK, so I finally measured the cylinder bores and pistons on my GS.
    Everything is at the wear limit, and the bores are 3 thou out of round.
    So even though it all looks really good, a piston kit looks in the cards.

    Sooo, what piston kit does the 'GS Collective' recommend ?
    Thanks in advance.

    Do you want to stay at stock-ish displacement or go up to 1085/1100 cc? For the money I'd go with a 1085/1100 Wiseco kit. Noticeably more torque on the butt dyno.

      If you are cheap, this guy has a low mileage GS1100 cylinder on ebay that didn't sell...http://cgi.ebay.com/ebaymotors/Suzuk...item45f2432699

      Stock 1100G pistons shouldn't be hard to find. Add about $100 for rings and you should be good to go for 1/3 of what a wiesco kit w/bore job will set you back.

      To measure is to know.

        I went with the Wiseco 1085 because it's cheaper than a stock oversize set

        I think that's most peoples motivation

              Would GS1100G blocks and pistons fit onto a GS1000?
