The engine plates have been fitted and drilled and the gearbox has been put in place to start the fitting of the new primary chain case.
The front of the new primary case is much smaller than the old case and the long term intention will be to mill out the webbed area that was the mounting point for the original primary case, however we didnt want to split the cases as the engine has recently been rebuilt so in order to fill in the area that would otherwise be a mud trap, we decided to make a circular plate to fill in the space until we next have the engine apart, when we can mill out the excess ally casting that is not required (see the middle picture).
We can now build the engine back up and leave it complete in the engine plates so that is can be put in and taken out of the frame as a complete unit without having to disassemble again.
