Hey guys just installed a 218/218 blue racer crane cam into my VN SS, The car runs excellent and sounds real nice. I have noticed that it blows a bit of white smoke now, mostly seems to be on start up. What could be causing this? could it have anything to do with the break in lube being used or anything like that?
Cheers guys

white smoke you say? white smoke is generally unburnt fuel.
could it be grey smoke? oil?

white/blueish is burning oil, n black is unburnt fuel could be running rich or maybe just valve steam seals and its burning oil.

Could be running rich. Bigger cams are not as efficient at low revs as the standard cam and will run alot richer. See how you go in a couple days

black is burnt fuel whilst overfueling.
white is generally unburnt whilst overfueling. blue/grey smoke as mentioned is usually oil.
