Drive it hard, but do not thrash it.
I also recomend having the oil changed at 3000km, use a good quality full synthetic oil.
For the oil to be a full synthetic it must be a 100% PAO or Ester oil, it wont be cheap but in the long run will save with; better fuel consumption, less internal wear, more power, longer drain intervals.
This is extreme http://www.mototuneusa.com/break_in_secrets.htm but a good read, I reckon he goes to far & forgets about other parts of the engine, like bearings & thrusts. But some people swear by it, I would not. |
Agree, but don't know if I'd change to synthetic oil that early - my BA felt pretty tight at 3,000 km. The fuel consumption is still improving at 12,000 km, which is probably a good measure of how well run in the engine is.
I think that main thing when running in is to vary the load and revs - don't just sit at 100 km/h on a straight, flat road but find some back roads with corners and hills. Also drive it hard at some stage once the engine's done a few thousand kms.
