How do Harley Davidson Turn a sportster 883 into a 1200cc machine?
Answers:
The very first answer is right, Larger jugs & pistons, Simple job and not all that expensive. You will be waisting time & money with a lot of the other answers.
The bottom end stays the same. The piston size and the cylinders increase the diameter. You will notice a big difference if the job is done right. It is a relatively easy process.
They will take the cylinders and bore them out to 1200cc and
put in new cylinder linings, replace the pistons and possibly uprate the carb for more fuel flow to a larger engine.
you might be cheaper getting a secondhand 1200 lump and droping it in yourself
punch it out
Bigger ,Pistons,cylinders and heads. The 883 and 1200 top ends are interchangeable.If you want some real power look into S&S top end,probably for the same cost as H.D.

Bore it out, switch out the pistons and some other stuff up top, and leave the bottom alone.
