I recenty bought a 1979 XR200 for $100 , it didn't run and made a odd ticking noise when you tried to kick it.   I took the valve covers off and noticed that 3 out of 4 rocker arms are broke.

Does anyone know what would cause such a thing to happen?  Also, on the top of the piston it has impressions from where the valves were hitting it.

I've looked everywhere for replacements rockers, but I cant find anyone who has them for sale.  


Can anyone help me?

Bike probably jumped time, valves hit piston, piston pushed valves upward, in opposite direction cam was pushing rockers, them pop goes the weasel. There's probably more damage than  meets the eye. Head prob needs to be redone. Either way pricey and unless the bike is beautiful, might be it's swan song.

Rockers are likely same part # used on xr200 up to 2002 and on some old atc200, xl185, xr185, and tlr200 of certain years.
