I'm guessing by the title that you have an Ultimaker 2?
If so can you take a photo of the nozzle assembly so we can see if there is anything wrong with how it was put together? Did you also change the PTFE coupler?

gr5 ->>>>> I have Ultimaker 2 I lowered the speed to 80% and seems to be working fine I am going to repeat the same test if it works again what do you thing could cause
That strange I just repeated the same test but I dial back the speed to 100% and seems to works great. Probably It was just anomaly. I had similar glitch when I tried to print large object.
Partial clog?

That looks like severe underextrusion. Assuming that's the side of your model.
There's many possible causes. What printer do you have UMO? UMO+? UM2? Other?
Did you replace nozzle with another .4mm nozzle or a different size?
It's important that the shell thickness is an exact multiple of the nozzle width - if not you get this kind of thing. This kind of underextrusion is most often caused by printing too cool or too fast - but first - what kind of printer? And secondly what temp, layer height and speed did you print at?
