Question
hello i am worryed about my yfz 450 engine. I let it sit for 2 years without any oil in it. Is there anything i can do to make sure theres not corrosen in it?

Answer
I doubt that there would be any problem unless you believe there was water in the case.  I'd just add some oil and with the spark plug unplugged, crank it over several times.  If everything feels okay, then I'd start it and let it wamr up then change the oil.  The other day I started a 125 Honda that had been sitting outside under a tarp for about 15 years and no problems at all.
