More often than not my FLSTFSE will not fire up when hot without a slight grind noise and sometimes buleish puff of smoke comes out of the air cleaner that smells like oil smoke.After it fires up all is good.When starting cold this never happens.It is a beautiful bike but this issue causes it to appear to others that could be watching to be somewhat lame.Is their anything I need to check?
