This quiz is now closed.  In the picture below there are 5 things wrong.  Answers and explanation of how it happened here.

T80 engine with arrowed faults

So what faults do we see?  You can zoom in on the photograph to better see the detail.  (To zoom in in Windows hold the Ctrl button down and press + on the number pad a few times.  Ctrl and minus to zoom back out.)  I've indicated the problem areas with the red arrows.

    1. The crankcase broke just below the joint with the barrel.
    2. The carburetor fell off probably due to the top of the engine moving upward, forcing the carburetor into the tank and breaking the inlet stub.
    3. The exhaust pipe has been forced off the exhaust stub.
    4. The tappet clearance is huge.  The barrel has moved and the pushrods jump out.
    5. The plug cap is dislodged.  You can see that the HT lead is pulled straight.

The engine in the photograph above was built and raced by Tony Harris.  You may remember that Tony came along to a club night and gave us an entertaining talk about the bikes he had raced.  (He can remember at least 38 but there were probably more.)  Tony did a lot of vintage racing. 
He had bikes for the larger classes and decided to build a bike for the 250cc and 350cc races.  Tony and his father had lots of Triumph Tiger 70 (250) and T80 (350) bits they could use.  They built a 250 engine that was OK but a bit fragile.  The first 350 engine went quite well and although a T80  would do thousands of reliable miles in normal road use, under racing conditions the crankpin would only do a few races before breaking.
The engine in the photograph above is the MK2 engine that would hopefully get around the problem of the crankpin breaking.   Unfortunately, as is often the case, you fix a weak point and the destructive forces move on to find the next weakest point.  In this engine it was the crankcase.
The blow up happened at a vintage meeting at Donington Park.  Tony remembers he was just coming under the Dunlop bridge (not there any more) when mayhem broke out.  He looked down at the engine to see what was happening and actually caught one of the pushrods as it jumped out.
Tony used his engineering skills to use stronger components. e.g. Velocette connecting rod and crankpin.  The MK3 engine had a modied crank to reduce the stroke to give near to square dimensions.  This third engine was reliable, quick and won several races.
