Title: 2 valve Jawa age?
Post by: Rosco86 on August 04, 2015, 02:05:22 pm

About to rebuild a 2valve motor. it is stamped 5371 with small Eso stampings on each side. Also above is a small 81.7 stamp. Would I be correct in assuming it was the 53 motor of that type made in 1971 and that the stroke is 81.7 making it a short stroke motor?
