The engine break-in went well and the engine now feels like it is supposed to.. so it’s time for some adjustments. After completing the break-in procedure, the engine oil and oil filter were replaced to get rid of any metal particles, dirt or gasket bits that may have been left in there during the assembly. No matter how meticulous you are, there will always be some dirt left in there and changing the engine oil is a MUST after running in the engine for the first time.

The next task on a boxer engine like this one is to check timing and valve clearance, the timing had been set to 0 degrees TDC to make sure the engine would fire up quickly and the valve clearance was set to 0.20mm for the break-in (rather too loose than too tight for the first run). Now that the lifter and cam have settled, i reset the valve clearance to 0.15mm using a feeler gauge and the machine feels a lot quieter. These figures are the same as used on a type-1 engine, the reason for this is because I am using a type-4 cam with solid type-1 lifters instead of the OEM hydraulic lifters.
