Once you have initially warmed it, get out there and give it some at moderate to medium high revs to get the ring to bore seal settled in.
Whatever you have done in the first 30 minutes or so is all you are going to achieve so dont baby it around. Get into it! keep the revs up but dont scream it
Change your oil early on in the peice.
Then, just drive it like you ordinarily would.
Enjoy your engine.

Im not a complete idiot, quite a few parts are missing....
its a 1916cc with an engle 120 so im assuming it be good for close to 7000rpm and i got told not to take it above like 3000 rpm for the first like 800miles, im assuming now that it is wrong, so, say take it out once warm and give it a few 5000 rpm changes and see how it goes???

My advice: Just drive between 2000 and 4500rpm, don't lug it up hills,use 'normal' acceleration and avoid city driving where the car is idling etc. After about 600km then start increasing your rev points at gear changes e.g. 4800rpm. then at about 800kms move this up to 5200. You don't need to change at these revs all the time, just make this your upper limits.At 1000km you should give it a full service. Then after 1000kms give it bursts to peak revs (I suggest you refer to your engine builder for this). Then just drive it however you want!!!!
Remember oil is cheap, so replace several times during the 1000km period.
