Depends what you want it for.

Do you just want a stock reliable unit or do you want something with a bit of poke?. Street use or for use on the strip etc?.

Whats it going in, bug, van, square, fasty etc?

TBH none of them were 'great' engines. 3 bearing crank, poor oil filtration, poor head port design. They were however super reliable & remarkably simple.

Which is best? The 1200 is a smaller lump (1300 & 1600 share the case) & has agruably better airflow around the cylinders but has less power than a sandal. The bigger units are still mega reliable.

If you're thinking 'hang on - they can't be that reliable because the damn things are always littering the hard shoulder on the M1' - they fail for 2 reasons, either poor oil pressure at high rpm caused by worn crank / bearings (due to lack of maintenance) or a fire due to perished fuel hoses leaking(again, lack of maintenance).
