Hi

Only 1 gasket?Weird...
If so,(i suggest u measured it correctly) get another gasket set of the PR2 which will fit on ur sp 2 too

A is the "smallest" piston.
B stands for an certain size,with the time and after "honing" a cylinder you need to buy spare pistons b,c,d etc...Cuz if u d keep using one and only size u d loose compression/power as the distance between piston and cylinder has to have also a certain space
