Ace 100 piston rings
Posted: Fri Jul 09, 2021 10:21 am
A while back I did some sleuthing on possible alternatives for Ace 100 standard rings. You would think that, with 50X50 being such an obvious 100cc combo, some other bike would be the same. I came up empty.
Today, by accident, I stumbled on the Suzuki A100 which was made from about '68 to '78 and I suspect may have continued on in Indonesia for a while longer. I remember them being popular in the South Pacific as general haulers and powering street vendor trikes and such back then. The whole piston looks pretty similar but with a 14mm pin. The expander spring, ring thickness and such looks oh so familiar and it's a 50mm bore, apparently. The oversizes are .050 [020] and .100 [040] so the whole range of oversize wouldn't be there but you could whittle the .050 down to .025 .
CMSNL [cmsnl.com] has a listing at 35 Euros. The Suzuki part # is 12140-12012. This bike was sold as the Gofer in the US, probably trying to climb on the Rat and Toad thing.
I've moved on to the Wiseco piston, but maybe these would fit. Or not.
