    3 1997 009 cylinders

    I have 3 009 1050 cylinders for sale. They are currently .020 over. Even with Weisco's (which are typically set-up looser than cast) they are on the loose side. It would be best to bore them to the next oversize. I'd like to get $200 plus shipping.

    Just a thought. The cylinders are currently with Jay in NY. If one wanted or needed to do a top end, and wanted to use the highly sought after 009 cylinders, they could buy these and get a top end kit from Jay. You could have them bored/fitted on site. Jay is currently boring cylinders for $40 a hole with the purchase of any WSM Top End Kit right now. Those WSM kits include All Pistons, Rings, Wrist Pins, CirClips, Top End Gasket Kit and Top End Bearings. So $200 & $275 & $120 = $595

    That would be a brand new top end using 009 cylinders perfectly bored, round, and fitted to new pistons with all rings, wrist pins, circlips, gaskets, and top end bearings for around $600.

    Either way, the cylinders are available.

    Perfect candidates for a punch out to 84mm, along with some port work, for a stout 1200 setup.

    If you have Sharps do the work, you save on shipping one-way because they're already there in-house.... just a thought.

    Sorry to stray off topic a tad, but I'm new to these domestics.

    Could you do 84mm (1200) pistons on the 1050 crank with the cyls bored that size?

    Unfortunately no. The 84mm pistons use a 22mm wrist pin. The 81mm from the 1050 uses a 20mm pin. The "compression heights" of the pistons are also different, due to the stroke differences, so that complicates it a bit more. There are some ~84mm Wiseco big bore pistons that are used in Polaris 700 snowmobiles that would work, however. You would have to have a custom cut head though, due to the dome angle differences on the piston, and obviously the change in bore size.

    Brad,
    Well put. Richie and I were discussing that yesterday, but there's no way I could have put it so eloquently. Thanks.

    Anybody? I'm surprised at the lack of interest for $200 plus shipping. For years I've been hearing how "hot" these cylinders are and how they're hands down the best ones to use.
