I got most of my parts from suzuki dealerships, as at the time i had trade discount.
any decent suzuki dealership should have no problem ordering what you need, i know prices cost more for genuine parts, but i recommend it for the engine. make sure that you have your chassis number at hand,so the correct parts are got for your anus.
valve stem seals are around £5 each, and you need 8.
part number for SJ410 v.s.seals is 09289-07007
as for piston rings there are 3 sizes for both 410 & 413,
standard, o.s 0.5, o.s 0.25,
as you anus is smoking , you be better off getting the engine re-bored at an engine re-borer , and they can get the new pistons, rings,bearings, etc to match the re-bore size.
its down to how much you can arrord to spend, other option is to get an exchange engine.
