    Cylinder boring service

    Anyone every hear or use this service? It is from an ebay seller?
    http://cgi.ebay.com/ebaymotors/ws/eB...2BSI%26otn%3D4

    $300 sounds like a pretty good deal but I am not sure about the WSM pistions. I just rebuilt a Yamaha 701cc engine and it was in the neighborhood of $400. I had a local machine shop bore the cylinders. He did a great job but I think I would like to try someone that has a little more watercraft volume this time around.

    Why not just get a Machinist that can do the Boring and chamfering Then order the pistons you want and take them down to the shop tell him the clearance you want and you have the same tthing they do minus the fancy graphics. They dont assemble it and you have to send them your cylinders

    I just rebuilt my buddies 800 with wsm and they seem to be fine so far, and they were a really good price.

    Just trying to save my mom some money. I guess by the time you include shipping it will be the same amount.
    I have used wisecos before. I setup the bores a little loose so they worked perfect. When I finally squeked them though I went back to OEM.

    I have run Wiseco with great success. they just need bigger clearances. a good speed shop should know that.

    i don't use any old machinist, cuz they won't have a good hone. find a shop that builds engines and you'll be set. a motorcylce drag shop does all my bore and hone and chamfer. costs $60 per hole, but they are masters and my stuff is always dead on nuts and runs great!

    That is a matter of opinion. I've seen more WSM pistons & rods fail than any other piston. Slap a Spec II on there and see how long they last...
