First off, use the oil you will always use and as I have always said, warm it up and drive it............

When breaking in the engine, alow it to idle untill it gets warm and then drive it........
It has nothing to do with oil getting to the top.........

What about breakin with new jetting? Say, you just rebuilt your bike, have a general idea of the jetting, so you throw that in, start the bike for the first time, let it idle, then go take it out and you have a bog somewhere..... keep running it with the bog to break it in, then fix/adjust? Or cut the motor and adjust jetting...? Get it running well then break in.... ?

run it at no less than 3000rpm for the first 15 minutes, then ride it for 5hours change the oil, then ride it for 10hours change the oil adjust valves if needed then ride it like you stole it.

Really, Ive never thought about it like that.. It makes 100% sense to me.
After a rebuilt i allways let it warm up and cool off compleatly, do that one more time than run the s*** out of it..

so what do yall think? run the hell out of it or easy break in? Also my questioin what if im building a bike from the ground up and i havent jetted my carb yet? I have to properly jet it or it will run like crap. Wouldnt that mess up the method that he described?

Yeah I'm confused on this myself I am in the middle of my build. New clutch,big bore,kibblewhite valve springs, and a stage 2 cam. With a full DMC exhaust. I have done my research I have a good idea on the jetting. But my question is this the break in for the cam is different from the break in for the rest of the engine so how would u properly break that in??? Thanks guys

So the break for the cam really don't matter then??? Its all about the pistonbreak in
Get the engine to operating temperature and then drive it the way you should, I wouldnt hold it full throttle for the first couple of top speed runs for more then a few seconds though............
