Curled up valves affect the attack of the reed, because it affects the first part of the cycle, the suction of the reed towards the frame. An improperly seated intake reed valve can result in gas leaking back into the low side during the compression stroke, raising the low side pressure and impairing the cooling effect. Removed the head. Otherwise there would be no improvement in top rpm engine power with a reed valve. Is this another/simpler/better way/not a good choice to do the pair value removal????? Directions seem striaght forward though I don't know enough about it to make that call 1 remove fuel tank 2 remove air filter. So a motocross bike can be decent without a reed valve. This means there are four lobes on one camshaft per cylinder. Multi-station float switches use a separate reed switch for each level point being monitored. If the reed valves are cracked, they may not open all the way, which will reduce the amount of oxygen that gets into the engine to mix with the fuel. It must work correctly at idle and at 10,000 rpms.
