After it taking Morgan 5 weeks to get the Stage 1 kit to my dealer they tried to fit it today.
The left hand pipe is over 1" too short so when the bobbin mounts line up the front of the pipe doesn't fit to the headers.
There is no mounting for the heat shield
And the coup de grace - the mounting bracket for the bobbin has about 1/2" depth which is less than 1/2 that of the bobbin thread. So the bobbin would need cutting to fit.
We didn't bother to look at the right pipe - they are on the way back to Malvern.
On the up side the air filter alone seems on first impression to make the engine a bit smoother.
