2006yz450f smoking

I just did a top end, piston, rings and cylinder, everything seems fine but riding today usually kinda only letting off the gas Id get a nice puff of smoke seemed blue of that makes a difference. Also 45 pilot jet 170 main won't idle to well and annoying bogg of idle, no idea where the fuel screw is haven't checked and haven't messed with the idle screw either. Any ideas?
