I have a 06 streetglide with motor work done , and it is smoking on decel, I have had new rings and seal in this motor twice now. The bike is also using oil. Can anyone help?

 

Hard to say without doing a compression test and a leak down test. Sounds like you are definatley getting oil into the combustion chambers which is not a good thing.

 

Sounds like bad valve guides to me. Sucking oil into chamber.

 

valve guides have too great a tolerance or the valve seals leak...possibly got smooshed by too big a cam with coil bind on the springs

 

The valve seals on stock-style 05 & 06 heads SUCK!

I would bet on the seals! More than likely, if you pull the throttle-body, you will be able to see oil weeping down into the intake port. I have an pair 05 heads in my shop right now that has "supposedly" better than OEM 05/06 style seals and they BOTH leaked!

Someone like Head-Quarters or GMR can work those heads over and replace the valves, guides, & seals with the tried & true setup that won't leak.
