- New


The BOYESEN BOY610 set of reed petals is designed for SUZUKI JR 80, RM 50, RM 60, RM 80, TS 80 from 1977 to 2004. In a two-stroke, the petals of the reed valve block open to let the mixture into the crankcase, then close to stop it coming back out. Tired or chipped petals don't close properly: the engine loses bottom end and sharpness.
Inspect the petals at least once a season and at every piston change; replace them as soon as a tip is damaged.
Boyesen is an American brand specialising in the intake and the engine covers of two-stroke engines: reed petals, RAD Valve reed blocks, engine covers and Supercooler water pumps.
Do I need to re-jet?
Usually not on a well-tuned engine; check the colour of the spark plug after the first few rides.
