caps, I've heard there is a late model RM125 slug that can be used but they're a flat top piston so this maybe the race fuel one?? The only other I've heard of people using in the A is a late model TSR125 (TS125R from the 90's) I was going to play with a T305 or T350 (can't rightly remember which
) slug as they 16mm pin but the bore size is something like 60mm or 2mm 'over' maximum wiseco oversize which in reality isn't a lot. 2mm rounder bore in all directions is all but I'm unsure of liner thickness to allow such an overbore. I never looked into this properly as I'm waiting for an actual piston to arrive with some other bits in the not to distant future but 'it maybe' a possibility and quite readily available cheap as chips. If the pin is at the correct angle to the cutaways and the pin height is within striking range then I don't see a problem. As for the barrel, yes it's waiting patiently for a home
