They either had short guides or weak valve stems Hyo have never admitted which. But the upshot was that the valves would break and kill the engine...

I've seen some fails on the 04-05 here even 07, good thing a non-oem heavy duty replacement is available. But it wont destroy the engine, more like heavy vibration and annoying noise, if it's critical, you wont even want to ride it until it's fixed, it wont allofasudden - bang!! like the head issue.

If you don't have the point in the picture below you have an problem with the 650 cc engine.

Most of the engines in America and Europe have an recall butt here in Holland we don't:
