Very nice
, had a RM125N back in 1980 and race junior 125’s good bike, I raised the compression by replacing the 1mm (copper) head gasket with a 1/2mm one, we moved the ignition 2° retarded I think. Than added DG reeds, port job, and an electron carbi.
Engine was slow until she came on hard, I could be last off the line and second in the first turn. Wish I kept the carbi, traded the bike at Savage Suzuki in Perth.
P.S love the RM500 in the back ground, rare horse.
