[QUOTE="vetwfo'er, post: 95846, member: 21011"] Unless you are, a one legged mule? I don't think you could kick it through TDC. You obviously had something pinning a valve open??? The first time you tried to start it, could you find TDC? Or was it only after you got it started? When it fired, were there any odd noises coming from the barrel. Like whatever had the valve pinned open, banging around. The compression release cable could have been tight and frozen and caused this??? Might want to check the routing and lubrication??? If can really trust the guy your brother bought it from, consider the bike ok. If not pull the head. You may want to do this any way to check for damage to the valve seat. Put a little gas in the combustion side of the head and blow compressed air through the intake and exhaust ports. Look for bubbles in the fuel sitting on the valves. This will identify any damage to the valve seat. Vetwfo'er [/QUOTE]
