    Default Max Bore size: 00 Ultra 150

    So with SBT sleeved cylinders, what is the maximum bore size you can go without working heads or other major engine work?

    I'm looking at boring the cylinders as they are scored, and I'm hoping to avoid a resleeve.

    The size that we bore the sleeves are the same as the stock O.e. bore, we dont offer any other size piston.

    I guess then, that you guys don't have any recommendations then on how much you can bore out sleeved cylinders? Stock and that's it?

    You might be able to find a piston from wiseco that could work but I couldn't tell ya what it would be from, If you do find something dont bore past 0.5 and you will not have to mess with opening the heads up.

    Why does the website offer the piston in both STD and 0.5mm sizes? http://www.sbtontheweb.com/Merchant2...roduct_Count=6

    John your correct, Its not listed in my shop book. If it needs to be ordered sales may need to find the part # online.
