cloudy oil?

[uncle niceguy]

Let me start by saying that I don't know much about mechanics so please forgive my ignorance.
I just had a 50mm bbk with head installed(at the local scoot shop), and it has about 250 miles on it. I've just changed the oil for the third time and the oil seems cloudy...I'm not sure if this is normal or if there was something wrong with the install. It seems to be running great the differance is night and day after the upgrade. It's a jonway yyq50-6 with a #95 main jet and #34 idle jet...it does bog down for a split second when I wot, but #88 jet seemed to be running lean, and I've read that that will mess up the valves. Everything else is stock. Any thoughts would be greatly appreiciated. btw i tried installing a # 38 idle jet but it flooded the carb. Thanks again, I'm new to scooting and love it, and love to tinker but i need all the help i can get.
