    Hi, I am looking for a big bore kit for my 2013 pulse adrenaline (k157fmi engine) I would prefer it to have 124cm3 marked on the cylinder rather that 150. I have found a few on ebay for Suzuki gs125 but I'm not sure if these will fit. If someone could point me in the right direction it would be appreciated!

    Thanks

    U need the flat (ie. Suzuki & clone after 00's 10mm "C" spark plug) variety
    http://www.engtaobao.com/item/528400923455.html & SAL seems the most economic way to buy such kit https://www.aliexpress.com/item/EN12...760466239.html also quite OK | Good old GS's piston = 凸 (ie. 12mm "D" spark plug)
    btw. Use better rings if u can http://www.mychinamoto.com/forums/showthread.php?8553

    Thanks for your help, these look good. Just wondering why there is the need for different rings and where would I get them from?

    Thanks again :)

    Most of time ring's service life from unmarked kit are similar to name brand's regular grade BUT http://www.mychinamoto.com/forums/showthread.php?8624 show it went from day 1

    Top grade rings had longer life | Regular grade from name brand at least is accurate in size & had decent service life | ??? = gamble

    OK, I will measure the ring gaps before I install them to make sure that they are the right size.

    Before I buy what is the consensus on big bore kits in terms of reliability etc? The bike is my daily transport so needs to be reliable. Can't see why it would be any different from stock, as it's not a huge increase :)
