Classic styling and strong performance made this tough old stroker twin popular. Could run to 50,000 miles without too many hassles. Most suffered cracked cylinder heads, leaking main’s seals, seized in engine mounting bolts and gearbox demise; some had oil pump failures. Sign of a good mill’s a slick gearbox, lack of exhaust smog and quietness. Check front TLS drum for cracks.
