X7 4 stroke oil question

I just got my thumper x7 and I was wondering if I should replace the oil in the crankcase.If so any suggestions as to what kind to replace it with.I have not even started this bike yet is there any thing different to breaking this in as opposed to a 2 stroke?

There is more to break in on a 4T engine.
Heat it up to operating temp.(hot) then let it cool down. Do this a couple of times then change the oil(use petrolium based oil not synthetic yet). Start it up with fresh oil and ride it without tearing it up(reving the engine too high to achieve an adrenaline rush) for 2 tanks of gas.Basically treat it the same as a 2T but only run the initial oil for the first start up! Run regular motorcycle 4T oil for the first 2-3 tanks to achieve optimum breakin. Then change to a Synthetic 4T oil from then on! This should get you into a long lasting 4 stroke engine. Change the oil whenever you think it looks like its getting dirty! I could tell you every 3-4 hours of use but it all depends on what kind of use it is! Don't let the oil get dirty and your engine will out last the bike!
