That Unifilter kit is looking like a must-have.

Has anyone done this? If so, can we get the results?
^^^^^^^^^^^^^


It's obvious that the air intake design is a significant departure from other KTM bikes that I'm familiar with. Until I see one live, it's more difficult to determine if there could be a problem with the seal of the box or if the problem lies in how the filter mounts and seals in place. Every air intake on every bike determines the ford height for water crossings. I wonder how much impact the tube system has on that, probably not much. Finally, before being convinced that there is cylinder or valve damage, the leak down test along with compression values should be reported. It is entirely possible that some bikes were poorly shimmed from the factory and KTM seems to have acknowledged that problem. A disagreement with the design team who implemented the airbox design is another matter, IMHO.
I think there was a legitimate request to activate this thread over this issue and I did not get any information or response when posted to the 1190 thread so I'm going to make it an issue here..............
