On a 2-stroke, the reed valve lets the air-fuel mixture into the crankcase and stops it from coming back out.
ITALKIT reed valve block for KTM SX 85, HUSQVARNA TC 85 and GAS GAS MC 85 from 2018 to 2026.
The ITALKIT LC.34.21 reed valve block is designed for KTM SX 85, HUSQVARNA TC 85 and GAS GAS MC 85 from 2018 to 2026. On a two-stroke, the reed valve block sits between the carburettor and the engine. Its petals open under suction and close again as soon as the pressure reverses: the engine's pick-up and power depend on how quickly they react and how much air gets through.
Check the petals at every piston change and replace them as soon as a tip is chipped.
ITALKIT is a Spanish manufacturer of engine parts for small-displacement machines: cylinders, pistons, crankshafts, reed valves and spare parts in several sizes. The brand is very active in 50cc racing, especially in Spain.
Do I need to change the jetting?
Usually not; check the colour of the spark plug after the first few rides and adjust if needed.
