I have a 2000 FLHTCUI with stage1, Samson pipes and a Power CommanderII. When I got the bike out this spring it is running rich. Rich enough that I can smell raw gas and there is black smoke coming from the exhaust. I pulled the plugs and they where black and wet. The bike was running fine when I put it up last winter. What should I check? Should I unhook the PC and see if that helps?

 

Vacuum leak,maybe?
