Hello all, I need some expertise to determine what is causing metallic bashing sound from my cylinder head. My bike is TDM -94 with 50000km (30000 miles) ridden (probably a lot more than that but according milometer
Here's the background for my problem:
Cylinder head gasket started leaking, I removed cylinder head and took it for machining and valve adjustment, inserted new cylinder head gasket, inserted cylinder head and cam chain => Cam chain did not line up totally correct (see picture. The angle of the picture lies a little bit, the 'E' is actually in line with cylinder head): https://www.dropbox....jxmi/O3N2q5brce
I assembled all bits and pieces and started the engine and there is this metallic sound like one valve is bashing somewhere (or valve adjustment totally wrong?). So I killed the engine and now I'm wondering where to start fault tracing. With my limited experience I have came up with the following scenarios:
1. Valve adjustment wrong with some valve (work was done by professional company but everything is possible, right?)
2. Cam chain timing is wrong. Can anyone say from the pic if this is the case (it's app. half tooth wrong)?
3. Cam chain jumped a tooth while starting the engine
4. Cam chain tensioner not working correctly => can this cause sharp metallic sound (or more like rattling)?
5. Exhaust pipes were damaged during dissasembly (torn under the flange) => exhaust fumes escapes directly from the cylinder head => does this have any affect on the valves?
Can you help a fellow TDM driver?
