Suzuki Set Valve Issues

Suzuki SET Valve Issues

My bike had a full decat and muffler replacement pipe but i decided to leave the Suzuki SET valve (exhaust valve) in place.  After a few weeks i removed the servo and left the SET valve as it was kept open by the spring, however i later had Suzuki SET valve issues.

25,000km later out for a fast ride with friends and suddenly the bike wouldn’t pull pass 5000 RPM, and when i backed off the throttle made  an horrific loud rattling noise.

Turns out the the plate on the valve had broken away from the shaft and at low RPM was rattling around in the exhaust and as the revs increased it lifted up and blocked the exhaust.
