Old oil filter

I just got the carb all cleaned up but I forgot to pick up an oil filter to replace the old one when I was at the dealer. Does anyone know how bad it would be to try and start the bike with the old filter installed ? The oil in new but the filter is aBout 8 years old which is the last time the bike was ridden. The dealer wont be open till Monday but I really want to see if the bike will run . I won't ride it just see if it starts. I promise . What do you guys think???
