Okay, here's my problem...  I pulled the cover off of my Savage after a long winter, rode her once and decided I was going to change the oil and the spark plug.  So, I changed the oil, filter and plug, did nothing else to the bike.  Started the bike up the next day to take her for a spin and about 15 seconds after I started her up she starts puffing out a whittish color smoke (kinda like starting a 2-cycle motor with to much oil in it).  Didn't really smell like oil burning and it quit after i revved the motor a few times.  But the past several times I have started it after setting overnite it does this.  What's the deal??

Let me clarify "quit after a few revves".  I should have said it quit smoking after a few revves and never smoked again throughout the day until I let it sit over nite and started it again.  Draining the gas and putting fresh in it would probably be a good idea though.
